Has anyone else had problems with their solenoids repeatedly failing to open? I am on my second constant solenoid and yesterday, when getting the coach ready to come home - the jacks would not retract - yet again http://irv2.infopop.cc/groupee_commo...s/icon_mad.gif . Well, a good whack with a hammer closed the contact, but it is scary to see the coach heading for your head as you lay under it, not to mention a pain in the a** getting down & up again.

i have had relays fail. solenoids leak. jacks leak, but i have never fixed anything with a hammer. could you describe where the part is located and where to hit it. i am always looking for new ways to avoid going to an rv garage??

Hi Doc,if the solenoid is activated with 12VDC,
is it getting the full voltage? Can you start retracting while still on shore power or after starting the engine.

Mark, I went through several solenoids on the Essex, I swore it was because of the way they were mounted and lo and behold I received a TSB and a bracket to turn them on their side...

I'm not familiar with your rig,but if your solenoids are mounted with the lugs facing straight UP and they're subject the weather, I think that's someplace to start...

The solenoids on the EXDP are mounted in front of the right front tire and directly behind the front cowl.

Hi Mark! Make sure your solenoid has been modified and turned sideways. If not get the update kit from Newmar. It solved our problem for awhile. We then had a bad ground connection under the HWH assembly up front. When that was fixed all of our problems cleared up. Paul

Something else I thought of and it'll depend once again on where your relays are located...

I had investigated the possibility of relocating the solenoid/relays over into the first compartment on the driver's side and all it would've taken was some 12V wiring...
That was something I was going to do, had I kept the EXDP...

Now owning the LADB, I have a bazillion more of those little buggers in addition to the HWH system....I now have a "fill" water solenoid to fill the water tank AND a "feed" water solenoid, which takes care of the water softener, keeping it from regenerating and filling the gray tank.....SHEESH!!

My situation is that the jacks will not go down. The road tech from North Trail thought it was a solenoid problem and he replaced it with a "sealed" unit. Did not fix my problem and HWH is sending a new touch pad and a complete new control unit. There is some guessing going on at this time as the exact problem has not been pin-pointed. But the key to some of your problems may be the sealed unit which prevents water from entering the unit regardless of the mounting position.

rebelsbeach 03-18-2007 12:40 PM

John, the remount kit is used even in the case of the sealed relays...
Nothing more than an "L" bracket that turns the relays on their side...

Sounds like Terry from North Trail is staying pretty busy,as another friend of mine over in Cypress Woods is waiting for him to do an awning repair BEFORE he can move his coach...

Brand new TS Select Limited and it's awning caught a microburst and flipped OVER the rig.

Hi John! I thought we got all the bugs out? See what happens when I leave Florida. http://irv2.infopop.cc/images/scared.gif When you say sealed unit do you mean just the solenoid, or did they come up with a fix where both solenoids and wiring are now sealed form the elements? Paul

rebelsbeach 03-18-2007 01:45 PM

Paul, he is referring to the solenoid itself being a sealed unit..

They've not made the determination that the entire shooting match needs to be out of the elements, although I MADE that determination with respect to the Essex... http://irv2.infopop.cc/images/oboy.gif

Hey Guy's
Read about this problem when we first got our coach.
The easeist solution is to buy a can of undercoating spray from your local auto supply store. Spray it all over that little thing.
For some reason, they mounted it in the gen dept right where all the water and grime from the road would get all over it! Over the right front tire.
Also, NAPA has a sealed one you might want to keep around. Part #ST85.

Generally those soleniods, the valving, the wiring and motor will survive the elements as they are used in under the hood applications such as snow plowing. I believe they are made by Fenner Stone.

Mark & Sheila,

My rig is older, but a few weeks ago my jacks wouldn't retract. I crawled under and checked some contacts and had Patty push the store button. I know what you mean by the coach comming down http://irv2.infopop.cc/images/scared.gif. But the problem came up again, and I couldn't even get them to manually retract by opening the solenoids.

A call to a friend told me it was a bad "shuttle valve". He told me to open a nut on top of the HWH manifold. I heard a metallic click, pushed the store button and up they went http://irv2.infopop.cc/groupee_commo...on_biggrin.gif. I thought I had an electrical problem too. I called HWH and they confirmed.

Check to see if your new unit has a shuttle valve.
