Title: fridge problems
Post by: corndog254 on August 19, 2014, 11:01:23 am
The Dometic RM7832 in my 98 U320 is not cooling well.  It has never done very well in hot weather and as I move south now it is really struggling.  I will be in Nac in Sept and called to get estimate of cost to replace with some kind of residential fridge.  Labor estimate was 22 hours.  Seems like a lot but window has to be removed to get the old one out so maybe justified?
Questions are:
Fridge is about 32x59.  Ideally would like to replace it with something same size but after looking over some of previous threads on this topic I didn't see where anybody had found something like that.  Samsung sounds good but I would prefer not to lose the cabinet space under the current fridge. 
So I believe my options are to lose the cabinet with a full height fridge (like Samsung) or drop back to 24" wide which I think can be found in the height around 59".  I would like to get suggestions, with current model numbers please, of fridges that people have either used or have found something they think would work.  I'm in a limited internet area and searching is a relatively slow process.
Next question, if fridge doesn't make it until I get to Nac does anyone have any suggestions as to where to go to get this work done?  I'm currently in eastern Montana, headed through NorthDakota, northern Minnesota, Iowa and then to Texas.  I read where some folks got theirs replaced for much less labor cost than 22 hours but don't know if their installations are a valid comparison with mine.  I do want to get a good job done.
Thanks

 BJ, I would suggest that as  a one person driver/user you will get by very well with a 10/11 cu ft fridge as we do and there are 2 of us (as others do too) We have the whirlpool unit that seems tough to source for some reason and uses very little power.
This model does not require a window out too which makes it cheaper to install along with the minor cabinetry changes needed. I do not know of any place for installation as we are in BC and I do all my own. I DO know that the prices charged by all are astronomical in my mind, having done it 2 times myself.
Sorry I cannot be more help, but if you change direction and head west then I can help!!

John,

Agree that some labor charges pretty high, but $800 at Parliament for R and R and cabinet modifications was real reasonable for a guy that wold struggle with the install myself (like getting old out and new in using forklift through the side window opening...

So if you are near St. Petersburgh FL, consider calling Chris in service at Parliament.

I paid $800 at Parliament, not $2200...full install - r and r and cabinet cut down. Â Plus ref rig was cheap. Â have $2K total, and I have french door full size counter depth

different strokes I guess

Had my Samsung 24 cf house type frig installed at Baytown, Tx, (Rudy Leggett's connection), the Lowes price at time was about $2,100, install $1,100, stayed in RV, in the garage, 1.5 days.  Feel they did a good job, yes, fork lift & thru slide window, 3 men at times.  If ever had issue requiring removal, would try to have them do the remove part.  No signs of that YET.

Yes, lost the space below the frig, but gained more usable space in frig, so net gain for me.

Not all floor plans work well for this installation and installer can make a huge difference.

Remember me if you pull the refer as I need the lock mechanism if the refers scrap.

If you turn the compressor on the whole refer gets way colder in ours at the #3 setting.

Uses a fair amount of battery power but does run off the inverter over several nights without sucking too many amp hour out of the bank.

Or try the #4 setting.

But I am not in a hot area so your results probably will vary

We also had out refrig replaced at the factory for $2200. Let me say, I stood outside the bay door the entire time they were working on the refrig. They spent about half that time actually working in the rig and the other half of the time getting called for help on other rigs. What I found is that most items you ask for to be done, big items, is $2200. We had this same number quoted to an air conditioner problem in the front dash, which is another story on our past Nimbus Foretravel. I have seen and clocked that what you pay for in labor is an over payment of the actual work done. I gues they need to cover their overhead which all companies need to do these days. I will say that the work done was great and the refrig looked great.

They worked three days on my fridge and had two guys too. They changed 18 hours but had over 30 in it that I could see.

They pulled all new fuel lines for me too. They had four guys on it for a full day and part of another and it was 23 hours.  I do not have an issue with the time and the one thing I had an issue with in remodel was brought to their attention and was cut in half.  I have to say that I have not had an hours issue with either the factory or MOT in years.

Post by: Carol Savournin on August 19, 2014, 07:08:02 pm
I agree with John.  We watch pretty closely when our coach in in the factory for repair In the past we have had issues like a slide bladder replacement, interior renovations and lengthy "punch lists" with myriad small jobs.  The techs may come and go as they are needed to help lend a hand at another coach, but we have never had an issue with what we considered to be excessive labor hours billed.  I am NOT a fan of their "restocking fee" in the cases of a part being ordered and then the issue turns out to require a totally different item.  Their percentage calculation seems entirely excessive in that area, especially when the part is not electronic in nature and has obviously not been used.  But THAT is a different conversation!

quote  " restocking fee" in the cases of a part being ordered and then the issue turns out to require a totally different item. "
That to me would also be a problem as they designed, built and sold the coach so surely they should know what is required to fix a certain problem and not hand you some cost of their mistake or just to throw parts at it and hope? I was in business for 35 yrs and could never have justified that tactic.

I would say you were very fortunate to have had great service. We too had great service up until this last past year. We had a air conditioner unit that is mounted under the front dash go bad. Apparently, the solder joints were not good. This was on our past 2007 Foretravel Nimbus. We were billed $2700 to resolder the fittings including labor and told that there would be no guarantee on the work. If the unit failed, then we would have to live without dash air since Foretravel used a vendor that was no longer making this unit and no other unit would work. It was up to us if we wanted them to try to repair it with the understanding that it might not work. Well, to make a long story short, it did not work, out $2700 and no front air conditioner for the driver area. That was the day we placed the coach up for sale.

My norcold propane fridge (don't have model) was replaced in my u270 2 years ago by previous owners. It works great, even in 90+degree weather and keeps my icecream frozen well on 3 or 4 (of 10 being coldest) setting.

I don't understand all the effort to replace with a residential fridge that sucks lots of electricity and requires extensive mods. I boondock a lot.

edit: want to add, no cooling fans or extra accessories either.

I recently replaced the cooling unit in the RM7832 that is in my 1996 U320.  I installed a condenser cooling fan kit at the same time. The refrigerator works great and I live in the Houston area where 98 degree days and 95% humidity are common. I am going to install a fan kit on the refrigerator of my 2005 coach as soon as I get the coach home.

If'n your fridge dies I would consider one or maybe two small portable units until you can get to NAC or where ever you chose. 

Perhaps a small freezer in the basement and a small fridge in you living area.  Inconvenient but would give you time to do a proper replacement.

The Dometic that came with our coach was dead when we got the coach. We had already decided that when replacement time came we would replace the RV refrigerator with a residential one. The old refrigerator came out through the door fairly easily. We spent quite a bit of time hunting for a replacement that would come in through the door and fit in the available space. We couldn't find one that would sit on the shelf, although we found some that would come close. The Whirlpool we bought is 11-12 cubic feet and is good enough for the two of us. It is about half the size of the one we had in the S&B, though, so we're having to learn some new habits. When the S&B finally sells we'll make an appointment at Nac for Dave F. to put in cabinets around the new unit. Until then we're talking about what we want.

I would look at getting a marine fridge. They are usually the same size as motor homes so they should bolt in and i believe there would be more room
in them as there is no propane and they use a compressor. They are more expensive the household fridges but the savings would in the instal
Title: Re: fridge problems
Post by: corndog254 on August 21, 2014, 10:44:49 am
Thanks to all who offered comments and suggestions.
The current status is that the fridge failed shortly after the initial post.  I called a service rep and he told me to look for yellow residue which indicated the ammonia was leaking out.  Sure enough that was the problem.  I think it was a slow leak which would explain why the fridge was not cooling well for quite awhile beforehand.  If I had known to look for that earlier I probably would have spotted the leak some time ago.  But I'm probably lucky that it failed finally without causing a fire.
So I'm in Bismarck ND going shopping today for a small dorm type fridge to keep me going until I get someplace, probably Texas, where I can get it replaced.  Right now I'm leaning toward the smaller but narrower one that would fit in the space above the cabinet.  John Haygarth's installation with the shorter fridge and the cabinet alongside looks great.  Would love to have something like that.
From what I've seen here on the forum I think there is a Whirlpool and a Haier model that might fit, so I'm looking for current model numbers that are available at this time.
Title: Re: fridge problems
Post by: bogeygolfer on August 21, 2014, 11:21:42 am
We used the Haier, and have been happy.  See my prior posts (with photos) on this if you're interested.  I don't yet have the side sliding pantry, but will some day.

Post by: corndog254 on August 21, 2014, 11:51:23 pm
Couple of questions for Bogeygolfer and John Haygarth.  I notice from the nice pics you guys posted that John installed on the left of the opening and Bogeygolfer on the right.  Any particular reason for those choices?  Also noticed that the fridge sticks out a couple inches in both.  I'm presuming that is to clear the hinge so the door can be opened?  Which way did each of you choose to swing the door?
Bogeygolfer, I think you had yours installed at Cutting Edge in Houston?  Did you have them do the whole job of removing the old Dometic and install the Haier, and how many hours of labor did they charge you?  Might be worth a trip to Houston.
I think I will be getting this done pretty soon so I'm trying to get some of the details nailed down that I will need to decide on. 
Went to Lowe's in Bismarck today to get a small fridge to get me through until I can get the new one installed, so I also looked at the Haier HA10TG20SB that was there (actually it was a HA10TG30SW) for $378, but I was disappointed to see that it had a can rack in the door instead of a shelf.  I don't drink sodas at all, so that is totally wasted space for me.  Haven't been able to find a version that has a shelf instead.  I did find that they had a 10.7cf Whirlpool model available for order (WRT111SFAW) that looks good on paper but is a bit larger so I'm not sure whether it will fit.
Title: Re: fridge problems
Post by: bogeygolfer on August 22, 2014, 01:38:51 pm
Sorry for the late reply!  Yes, we had our done at Cutting Edge in Baytown upon the recommendation of Rudy Leggett and we were very pleased.  I really can't say enough good things about our experience there - they helped me fix a couple of other problems that had been impossible for others to fix. 

Our invoice reads as follows:

"R&R Refrigerator, removed window for refrigerator exit point, stain and install wood for trim....6 hours"  the piece of walnut was an additional $75.

As for the position: I think the right side just allowed the doors to swing open fully.  Not being in the coach right now, I can't remember exactly, but I think if it was left-justified there was some problem with the doors opening all the way.  Also I looked at Rudy's (he has a sliding pantry built in to the left of the fridge) and just liked how everything worked.

We, too have the soda holders in the door and we use them; but yes, I agree that shelves  there would be much better overall.  I think one of the only regrets I have about the residential is that there are fewer specifically-designed spaces for RV-type use.  For example, the original fridge had nicely-designed shelves that would hold things in place while traveling.  This one has much more space, but unless you have it packed pretty full things will probably move around in the big space inside.  Well worth the tradeoff, in my opinion.
Title: Re: fridge problems
Post by: John Haygarth on August 22, 2014, 03:17:27 pm
 Reason for left position on ours was I figured the pantry would be used more than fridge during day so closer to sink/counters etc. The door does not open full 90 deg + but good enough to get crisper tray out for access and cleaning. Door swings to left so you can get in it from cook top side. The finished install is not a problem for use even though the door is comprimised a tad. I would not change decision if I had to do it again. I was on my own doing job other than a neighbour helping to carry old one out the door, and figure I had it done in 3 days(fridge & cabinet) but waited a couple weeks for the pantry door to be made to match others.
Good change from original. Our fridge door has milk etc shelf at bottom and an upper rack for other things.

See below the containers we found and modified, for the inside of our Whirlpool fridge to keep items in place and to make better use of the fridge. We also put spring bars on each shelf before we travel to prevent items from falling out when opening the fridge door after we stop. (We also put spring bars on pantry shelves for the same reason).

I just got finished replacing our RM 7130 with a Samsung 18cu ft model. The Dometic was heavy. Window removal was a breeze. Rented a hand cranked lift ($40/day) to lower old unit from window. With all doors and shelves removed, the Samsung was easily lifted thru the window by 3 guys. Window reinstall was a breeze. Really, the most complicated part was the cabinet preparation. only think left to do is trim it out. Going to use the matching wood panels from Dometic to make trim. Will post some pics.

John and Bogeygolfer - thanks for the replies with the additional information on your installations.  Photos are a great help.  Sounds like Cutting Edge was a good outfit to work with.  Did you make any changes to the fridge outside access door?  Or the vent going up?  I guess it still needs vents for cooling but the big access door would also let a lot of dust in.
John, did you install a Whirlpool, and if so what model?  Maybe I could still find one someplace. I'm trying to avoid the can rack that is in the Haier.  The Whirlpool Lowe's can order now is  WRT111SFAB which is maybe a little too big?  Has anyone successfully installed one of these without having to mod cabinets?

 BJ, it is a Whirpool and will later send model#. I have not changed lower vent but did take off roof vent and close it off, but then drilled the added piece  and installed one of the Whirley Bird type vents. My old one was breaking up (rotting). I will see how it (new vent) fairs in Jan in Mexico heat as to weather I change it for something else or??

I am having a custom marine refrigerator installed, but most of this still applies.

The installer is keeping both side and roof vents open for air flow.  The sidewall vent has a galvanized sheet added to keep water spray and wind driven rain out.  The roof vent has a thermostatically controlled 12V fan added to improve airflow when needed.
Title: Re: fridge problems
Post by: Paul Smith on August 25, 2014, 01:23:27 pm
Yeah, Tom, as you know I have a marine refrigerator, too.

If I recall aright, you have two compressors, one for freezer, the other for refrigerator.

I'm not sure if your compressors are remote from the freezer/refrigerator box, or if the boxes are seperate.

I have a single compressor for a 12cf box. Its on a shelf next to our freezer/refrigerator box. I did it this way to have more cf in the freezer.

Foretravel roof and side freezer/refrigerator vents are open.

Even in very hot weather the freezer/refrigerator maintains a cold freezer/freezer/refrigerator box as we go down the road.  No fan needed. Typically right now even parked the freezer is at 11F and freezer/refrigerator 40F. Ambient today here in the SF Bay Area is 64F at 10a. Ambient will climb once the sun burns thru the clouds.

While parked I keep  a close eye on ice buildup. The easiest way to tell I've forgotten to defrost is to see the freezer temp start climbing.

Like you I run my freezer/refrigerator on DC. (Eliminate the middle-man ;o) I do have the AC option.

All in all I'm very pleased we went marine freezer/refrigerator. It just does what its suposed to hour after hour.

I do turn the fridge down when we go to bed. Around here it will only be up to 45F by morning

best, paul

Mine is ready to pick up, but me getting out to pick it up is day by day.  DW has health issues, keeping me from getting out of the house long enough to go and get the RV.

I went with the two compressors built into the box, taking some room away from the refrigerator.  I posted the build sheet a while back, the total is around 14cf, plenty big enough and bigger than the Dometic it replaces, and this is with four inches of insulation on all sides but the door.

I bought a wireless refrigerator/freezer thermometer with separate senders for the refrigerator and freezer so I can monitor the actual temperatures without opening doors.
Title: Re: fridge problems
Post by: Paul Smith on August 25, 2014, 04:24:36 pm
Yeah, I have those wireless thermometers in the box, too.

I have the compressor outside the box so it could be worked on/replaced without pulling the refrigerator into the hall.

I hope the health issues go to the better side.

best, paul

BJ,

I don't know what your refrig is like regards the installation.  I'm talking about the distance between the back of the refrig and the outside wall.  The floor plans for the 98 320 36' shows the back toward the side wall.  I replaced mine with as close to original as possible when it was about 12 years old so I didn't have worry about a failure on a trip.  I did take out a window, not real difficult if you are handy.  I also borrowed a flat bed truck at the storage yard to stand on outside the window.  Take the doors off the old and new units first.  Helps to have a low sturdy table the height of the bottom of refrig cabinet.  Installation instructions said the back wall should be close but not touching the back of the refrig, so I built a false wall to close up the space.  It worked okay in Vagas in July.  If you are not handy do not attempt.  Hope the link to my old post works.  The cooling could something as simple as a dirty flue stack, ie mud daubers, etc.
Foretravel Tech Talk / Re: Refrigerator not Cooling ???  Didn't work so adding this.

Follow up to my previous post in this thread.  Installed the new refrigerator and it worked.  Replaced the Norcold 682 with a Norcold N841.  Removed the window at the kitchen table to get the old one out and the new one in.  Storage yard owner backed his flat bed truck up to the window so a couple of helpers could stand outside the window.  Removed the refrig doors and they went in and out with the door opening down.  Not very hard at all, nothing got scratched up.  Had a furniture blanket on the window opening and table.  I didn't have to do any trimming of the cabinet opening to get the new one it.  It fit perfectly. 

After removing the old refrigerator, I was somewhat appalled that Foretravel did not follow the installation instructions for the old refrig .  Usually they are very good about that sort of thing.  The area above the refrigerator was not blocked off and there was too much space behind the refrigerator.  Apparently that is important as the airflow in at the bottom and out at the top works somewhat like a chimney does.  Before I picked up the new one, I built a baffle wall to reduce the space behind the refrig.  Just a couple of pieces of wood fastened to the wall with screws and piece of thin aluminum sheet metal fastened to the wood.  I did put some fiberglass insulation behind the aluminum.  Stapled some insulation to the ceiling above the refrig and added a piece of aluminum to block off that area.  The ideal installation seems  to have the refrig as close to the back wall as possible without touching it.  Up to 1" space is okay; 1 - 2" add a couple of baffles; more than 2" build a baffle wall.  The old instructions do not mention a baffle wall, but the new instructions do.  Foretravel insulated the sides of the cabinet, a good thing, also the fit is very close on the sides which is good.  I added some metal on the side wall near the burner exhaust where the foam was melted.  It doesn't extend along the side of the refrig though as that would transfer heat into that area.  The trim around the front of the new refrig is not quite as wide as the old trim.  The wood outside the old trim is darker than what was under the old trim.  Didn't look good, so masked off a small strip down the sides and painted it black.  Needless to say both the old and new refrigerators went in and out of the cabinet several times, before everything was correct.  This would have been a real problem without the little table level with the bottom of the opening.

Started the refrig at 10:30 am with the temp setting at 5 (range 1-9), shut off the generator and air conditioning and went home.  Returned at 7 pm 8 1/2 hours later; coach interior 106 F, outside 99 F, Freezer 0 F, Refrig  39 F.  At 10:30 am the next morning coach interior 91 F, outside 87 F, freezer -2 F, refrig 37 F.  I think it is working okay.  I have no fans, but nothing was in the refrigerator and the doors stayed closed.  The temperature shot up to about 50 F in the refrig shortly after opening the door. 

There are some differences between the old and new.  Some of the plumbing on the back is different but the major parts are in the same places.  An overheat sensor has been added near the burner area.  There is supposed to be an audible alarm for door open, no flame, no ac, etc  I haven't heard it, but the visual indications work as advertised.  The manuals are rather hard to use, all the illustrations are on the last pages after the french section.  The wiring diagrams have lots of numbers and letters that have to be looked up in the middle of the book.  Finally printed out that page from the website to make it easier.  Norcold does have a manuals section on their website. 

Inserts for the door are purchased separately and the old ones are not wide enough for the new doors.  I made my own from 1/4" oak plywood which is 7/32" thick, still too thick as 3/16" is specified as the correct thickness for an insert.  Plywood will work though if the edge thickness is reduced with a belt sander on the back side.  There is still space between the panel and the door in the middle area.  I choose plywood over plastic as it is has slightly better insulating qualities.  Sealed both sides with 2 coats of thin dewaxed shellac and 3 coats of Miniwax satin finish polyurethane on the good side.  Light sanding between coats.  Shellac is not water resistant, but it does slow down the movement of moisture in and out of the wood.  The color match with what is in the coach is very close.

BJ,

No, we didn't change either the roof vent or the lower access door. I just replaced the roof vent a year before, and figured since it was new that I'd leave it. Also, I used VHB tape from 3M to attach it, so I'm not looking forward to removing it. I thought some circulation might help as well. 

I also did nothing to the lower vent door. I think it's just fine as is, and I've noticed no bad effects from it.
