I got the new solenoid from HWH off of their web site, new one was identical to the old one including the plug. unplug the hot wire, unbolt the ground to the solenoid and take the bowl off, it has a screw collar at the top, and work on it on a bench instead of cramped in the basement Quote Selected 1 Likes
Re: compressor "cycling" every two minutes Reply #26 – December 06, 2017, 10:23:37 am Roger that. I take it I would need a 1/4" plug for the solenoid. How about if I remove the glass??? Can I operate the compressor without the glass/solenoid combo. And WHERE does the solenoid dump the moisture?? Into my storage area?? How come there isn't a puddle of water? Or a big rust area? You guys are very helpful. I'm learning a LOT!! Quote Selected

That compressor only supplies pressure to bags and slides when engine compressor is not running and pressure falls, so not that much water is trapped. Mine will evaporate every day. Drill an hole and run a hose out of compartment if it bothers you. Quote Selected
Re: compressor "cycling" every two minutes Reply #28 – December 06, 2017, 10:52:39 am It vaporizes a very small amount of water relative to bay volume, as we duscussed and Jim noted in this thread. Not a problem. As we discussed, unplug solenoid to make it cycle, see if fixes hot vaporizer as first step on it, check glass cylinder for leak using soapy water if you cannot feel a leak with your hand. Helps to crawl up in the bay to more easily see this.Have you done those and found these not your problem? Think you have but i have not gone back thru thread since we talked to be sure. Those were the first options for leak after you isolated the slide bladder, which I trust you did with the valve cutoff and credit card? There can also be a check valve failure on this model coach that causes problem but that less likely than the first troubleshooting....we can talk of that if you find cylinder not leaking. There is also an option for a leak on the block but it too less likely.I would add a air pressure gauge to the aux, monitors the third air tank. Been great for me to monitor pressure and rate of change in psi. Also lets you monitor the solenoid settings for turning compressor on (65 psi) and off (85psi). Add rocker switch so can turn off the compressor. I count this as important for couple of reasons. As for compressor failure, at one time I was going to replace the compressor with model that comes on later coaches. Was told by tech I did not have good idea, fix what have....it is pretty strong, turned be good advice. Did not even require a rebuild and we have 150,000 miles on it but if overheat too much too often I am told can deteriorate some internal parts need to replace.I am concerned for you....you making progress on this or need something?

Re: compressor "cycling" every two minutes Reply #30 – December 06, 2017, 02:18:32 pm All the threads are pipe threads, "NPT". Would take the solenoid with you, mine is 1/8". If bowel is leaking, take entire separator to home depot and have someone there give you pipe fittings just to bypass it until you can get the right part. Quote Selected

Re: compressor "cycling" every two minutes Reply #33 – December 09, 2017, 05:31:25 pm The sun is finally out. I sprayed the solenoid area with bubble solution, fired up the aux compressor and watched a lot of bubbles get made. I can feel air being blown downward. GOOD news, I guess. We are moving Monday, so I will wait to work on it for a couple of days, as long as I can pull in my slide and move the coach without any problems. I have read on a concurrent thread " HWH Auxiliary Air Issue ", that someone bought a solenoid from HWH ( for $120 ??wow ) . Then someone got a replacement glass from MOT?? Is there a way to purchase BOTH from one source, should I need it?? I will try to take it apart and fix it, but might need a replacement. The wires will have to be cut. I have a MALE connection on a black wire with a tag that says " To Water Trap Solenoid " , but there is NO FEMALE part to hook into ?!!!! Anyone know what's going on here. BTW....should the two threads be combined? They seem to be dealing with similar issues ?? Quote Selected

If there isn't, the valve is open and that is why air is leaking when compressor running. Quote Selected

Re: compressor "cycling" every two minutes Reply #36 – December 09, 2017, 05:59:04 pm Actually dc coils are not polarity sensitive. As long as you have power to the coil, it should work. Believe hot lead comes from pressure switch and other should go to ground. Solenoid valve on bottom of separator bowl will close when compressor running and open when compressor stops if wired properly, Hold a screwdriver next to coil when comp. running, if wired correctly should be magnetized.

Re: compressor "cycling" every two minutes Reply #37 – December 09, 2017, 06:43:52 pm Thanks Tim, will do. Jcus... didn't mean to mislead you. There ARE two wires coming off solenoid. One goes up to a small green board and seems to be the ground I have to trace the other. I w\Have to dismount the compressor to get to the bowl. My hand can't fit behind the compressor otherwise. The two wires were wire tied to the support. I will cut them free and trace them. I have NO IDEA what the coil looks like. Also, people keep saying they remove the fuse to stop the compressor from running. I cannot see any fuse. I disconnect the red hot wire to stop it from running. I will probably install a switch, as was recommended by Michael and Jackie. I don't see how or where to install a gauge, but am searching past threads for info. Quote Selected 1 Likes

The coil is the round thing with two wires coming off of it on the valve on the bottom of the glass bowl on the separator. This is what closes the valve when the compressor runs. Go back to the link I pasted with hwh filters and bowels and you can see it. It should be magnetized when comp running and if it does not leak when comp running, don't worry about it Quote Selected 2 Likes
Re: compressor "cycling" every two minutes Reply #39 – December 09, 2017, 07:36:45 pm OK. IF I get this right, I am trying to see if the solenoid is doing it's job by putting the screwdriver on the end if it while the compressor is running?I KNOW I have a leak between the glass container and the solenoid. When I can, I will disconnect the two wires from the solenoid and unscrew the glass by turning a black ring at the top of it. I will then look at the connection and try and find the leak. Hopefully, it is some type of "O " ring.I am new to all of this, so I must ask, once again:Will the silde/ bladder operate without the aux compressor?? My main tanks work fine, lots of pressure. We are leaving Monday. I will work on the aux compressor when we next stop. Thanks, all of you. Quote Selected 1 Likes

I will go under tomorrow and try and locate the inline fuse. Didn't see it this afternoon.Yes, that should have a female connector, it is obvious that the valve is leaking air when compressor is running, because it needs power to close. Your main engine compressor will supply the air you need for slide bladders etc. Suggest you start main engine before you move slides so you are sure you have enough air pressure for them, if tank pressures below 90 psi.

Re: compressor "cycling" every two minutes Reply #42 – December 09, 2017, 08:01:17 pm We purchased this coach last January. Full timed until first of June. No problems with aux compressor. I may have noticed short cycling this summer. Not sure. We have been full timing since first of October. How can we have missed this, AND Wayne at OTM miss it when I asked him about short cycling last month?? How can I fix the wire problem?? Can I splice into another wire on the compressor?? Which one ?? Feeling a little uneasy about now. Quote Selected

If leaking from top of bowl, might be able to clean up and teflon tape, But solenoid valve has to have power to close or it will stay open and comp will not build up enough pressure. You can run without aux compressor. Suggest you level with engine running then shut off hwh system. If you do not have bag/leveling valve leaks, you should stay level. Aux compressor is for slide seals and leveling when engine is off. It will help you to troubleshoot, if you learn the names of the components in your system. Quote Selected 1 Likes

Re: compressor "cycling" every two minutes Reply #47 – December 10, 2017, 12:01:37 pm Quote from: GleamB – December 10, 2017, 11:16:07 amI will look at it more closely today, and take it apart, since I don't need it to pull in / extend the slide. Will let you know what I find. Think of it as a type of "filter", when compressor is running, air is compressed and goes through separator and water is "filtered" out and drops to bottom of bowel. A long as compressor is running, solenoid valve at bottom of bowel is closed and water will build up in bowel. When pressure switch [gray box with wires coming out] sees that pressure is proper, it shuts off power to compressor and to solenoid valve. This valve will now open and allow water to drain out, because it is normally open and only closes when the solenoid valve, [coil is electrical end of valve] sees power, as when compressor is running. The coil is just an electric magnet that closes valve, that's why a screwdriver will stick to it if it has power. The solenoid valve does the same thing as your manual tank drains do, but does it electrically. Quote Selected
Re: compressor "cycling" every two minutes Reply #48 – December 10, 2017, 12:53:17 pm This post is way out of order but wanted to note:The Pitcock in my posting of a couple of years ago was placed there by our previous owner. One of the solenoid wires was not attached to the coil on that solenoid so the PO attached that pitcock to control air flow. I would open every few days and empty the glass bowl. With the assistance of a fellow FoFum member I was able to disassemble and repair that solenoid and removed the pitcock. Quote Selected
Re: compressor "cycling" every two minutes Reply #49 – December 10, 2017, 02:59:06 pm I was under the coach again to get a better look at all things. I ran the compressor and it was leaking where the plastic bowl and the solenoid meet. I traced wires that are in question. The two wires that go from the solenoid below the leak both go to the small " green board ". One wire seems to connect to a post. The other goes thru a connector like the one I am missing part to. It also goes to the board, but looks as if it is soldered in. It is tagged " to exhaust solenoid ". The wire that has male only is tagged " to water trap." It goes to the green board where it looks soldered in. No female for it anywhere. I tried to release the plastic bowl so I can determine why it is leaking. I could not figure out how to release it. There is a black ring at the top of the plastic bowl, but I would have to get a channel lock on it.....IF I SHOULD TURN IT. If I have to turn the clear bowl, and leave the black ring alone,I fear that I can easily break it. So....how do I get the bowl out and what should I do about the disconnected wire. Quote Selected
