We replaced our original Sharp convection microwave model with a new Sharp model. The original microwave was still working just fine and over the years we have fixed a fuse holder (would not run) and replaced convection thermistor (convection overheated), but we figured we were in the right place to update our microwave. We prefer Sharp convection units as they have a good repair history and work well when installed right against a side wall because the door hinge is 1-3/4" from wall and there is no door handle sticking out. It comes in several colors, but black matches our Whirlpool electric refrigerator, which is next to microwave.
We have microwave power plug on a switch so it is disconnected from shore power when not needed, to help prevent damage from unplugging shore power or starting generator, etc. And Sharp does not require a clock set after power has been removed.
In the past, we had taken our original unit out to replace thermistor, so we knew what we were up against in lifting it out, but we were not sure what it was going to take to install the new style wall mounting plate.

Barry,
Did the wall mount come with it or did you have to order it separately?
Thanks,

I just put in a GE to replace my sharp.
Pictures........:-)
Have the GE, NAC in spring, new electric cooktop, out with Propane, in with more batteries!
Will take a few as soon as we are done.
Wall mount does come with new microwave. Nothing but new screws are needed.
Barry .... Thanks ... Jimmy
Looks like Home Depot has the best price. $428.49

Greetings,
Just installed a Samsung - not meaning to interrupt your topic..
I saw that yours was an 850 watt is that the original? Since mine dumped, just wondering.
I put in a 1000 watt, still within inverted capabilities.
Thanks
Thanks Barry & Cindy for the step by step directions. Thanks Ken for the pricing. Ours is on the way.
Grant & Betty
My coaches previous owners, Richard and Betty Bark, installed that same unit in my coach. Works well even with my old non full wave inverter. Thanks for the nice work.

We have the new Sharp ready to install but haven't been able to remove the existing microwave (Sharp R-1831B). Try as we might, the locking tab/levers won't release, in fact they won't come down more than 1/4". The microwave has no movement at all (back, forward, up, down). We've taken out the screws at the top front Barry mentioned and removed the plastic covered screws securing the locking tabs.
We are wondering if anyone else has run into a similar problem?
Grant, I don't know if this will help... but a couple of years ago George installed our new Sharp R-1875T. However, our old unit was a Sharp-1870, not an R-1831B. But, just in case, here's his procedure for removal/installation: Removal of Microwave (Sharp R-1870) (http://www.foreforums.com/index.php?topic=13433.msg78725#msg78725)
Yep, thats all the rear tabs come down 1/4"or so, believe me they are unhooked.
John H told me to keep looking for screws and guess what found one behind the top right void space, in my u280.
Grand there are screws in the sides also. 3 were in my spice rack. Sorry I didnt see your coach type.
Success!
One last screw, through the wall of the cabinet over the sink and into the side of the microwave, the screw head was hidden behind a light switch cover!
Thanks John, Pat/George and Barry/Cindy. Also, good idea to use the ottoman.
Grant
Grant... glad George's post helped (as did the ottoman suggestion! :)) ).
I was a little startled by the readings from your refrigerator/freezer thermometer (we have the same Chaney unit, and mount it on the side of the microwave, too!).... until I realized it was Celsius! :o :P :P
Good eyes!
George and Grant,
Thanks to both of you. I had read George's account earlier but I somehow missed that sneaky side screw. I had tried to remove my microwave some time ago for some backsplash work and could never get it loose. I knew I was missing something but never figured it out till now.
@Grant thanks for the pics! I tried to pull mine last year sometime and while I got the rear support undone the microwave still wouldn't come out. Just checked my cabinet and see the same switch cover.
Looks like baby is getting a new microwave!
see ya
ken
Thanks to the instructions from Barry & Cindy and the help from Patricia/George & John - we now have our new Sharp R-1871T in place and working!
Here are a few more photos. However, other than the one hard-to-find screw ( :facepalm: ), we can't add anything to the instructions Barry & Cindy posted earlier.
Thanks all!
Grant & Betty
Yes, on the older models they sure hid those screws as it took me a while to figure out it was hiding behind the halogen plastic protection cover. That is why I told " foureye" to keep using them (eyes). His was in same place as mine.

John H,
You da Man, saved me; U280 microwave replacement, full of detailed photos AND that pesky screw. ^.^d
We have our microwave/convention replacement scheduled for this weekend. This thread is VERY helpful! Quick follow up question.
Q) What type of screws should I use for the new mounting plate? Metal? Self tapping? Wood? Length?
Are you going with another Sharp microwave? If so, there's a good chance you'll just be able to reuse the existing mounting plate.
Sorry this doesn't answer your question directly. You're likely not going to get a stud where you need it, much less multiple, for the mounting plate so you'll have a thin layer of wood (1/4"? need someone to confirm this) and then foam to work with. So it'll be a matter of quantity over quality. Much of the weight of the my microwave was actually held by long wood screws that went into the cabinets from above the front faceplate.
I used the new mounting plate but the old one would have worked just fine. If you do use the new plate, try to use the old screws, in the same location as the old plate.

We found that the "1996/97" Sharp microwave used a different bracket system than the replacement Sharp we installed. We could not reuse the original metal bracket.
Seems that the internal wall space behind the microwave is probably a solid thick piece of wood, so the bracket can be securely mounted.
Sharp has the advantage of having door hinges not located at edge of microwave, allowing a better door opening when microwave is mounted flush to the left side wall.
Based on the model numbers and everything I am seeing from the threads, the existing and new mounting plates are different. I will try to use the same/similar screws from the original mounting plate.
On a positive note, we have already put the same Sharp convection/microwave in our stationary home kitchen so we've got experience putting in the new one. ;D It will also be nice to have the same unit in both places.
The new unit (Sharp R1874TY) does have two large screws in the TOP that go up into the cabinet above to hold it in place in addition to the mounting plate on the back. I have not seen that in the replacement threads.
When I replaced our Sharp microwave for a Samsung, I used the same plate on the wall and drilled new holes in the upper cabinets and inserted the holding bolts for the main weight of the microwave. I have probably replaced well over 100 microwaves in my remolding years! Been hanging there now for well over 2 years of travels and no issues. Would I buy the Samsung again? Yes and no. I like some of the features and some I don't. I tried to purchase the Advantium by GE, but could not locate any at any store. Still can't, but it seems that Newell and the new Realms are installing these. Would like to know where they are getting them. I did check with FOT and was not willing to give the add on price they were wanting to charge for such. Now, wish I had bite the bullet, as the Advantium, in my humble opinion, is the best of the best out there! Let me know if anyone found one at a HD or Lowe's, as I have searched over many states.
Best Buy shows one on their website.

Not sure you have those were you are but I'm sure they would ship it to you.
Try ABT in the Chicago area. They deliver all over the USA and are a stocking dealer for many brands.
They have great prices and are fantastic to deal with.
Best prices come from calling and talking to a rep.
I put in the Samsung MC17T8000CS and have been very happy with it.
Pacific sales, which is owned by Best Buy here in San Diego has them.
When we upgraded ours the new one required the new backing plate, it had lots of hole options, some lined up with the steel framework, reused the existing mounting screws. Drilled a couple new holes in the plate to match the old one. Lots of options. Sorry but I don't remember the exact size and type of screws, I just reused the old ones.
Multiple wood screws into the wall on the backplate should work fine as the majority of the weight is supported by the front bolts that go up into the cabinet above.
Hate to change out a perfectly good microwave now, but good to know. Could not find any at the time and even with a call to GE, they stated out of stock and not sure when they would put in production again. Thanks for the links!
