Smart Bed Issue

[Jerry Burns]

My first smart bed on the curb side will creep out about an inch after setting for three or four days. You can hear the pressure release from the valve when it is fully closed. Nothing happens for two or three days then it will be slightly open. Any ideas.

Mine front one on the PS side does it after about a week. I live with it. If HWH and I ever meet up at a rally, I will have then find the errant solenoid and replace it. The vanity slide creeping in is what bugs me the most, we just leave it in, because it never stays out, cannot figure out how to determine which Solenoid it is, but HWH knows about it, and it going to be fixed once we head south at a place recommended to me on this forum in Medford, OR.

There may be a timing issue involved here. We've had the main slide want to creep out after sitting for more than a week in the RV garage. Carrier & Sons has identified the issue as a solenoid. Their assessment is that the issue is not time critical, but that in time the solenoid will require replacement. What they've added to the conversation however is that when they need a replacement solenoid from HWH they're now told that they are no longer is stock, and that each replacement solenoid needs to be manufactured separately to fill an order. It is both time consuming and apparently more expensive -- but there don't seem to be any obvious options.

Old & RVer's- I believe both of you have extra solenoid valves. Toward the end at least, WRV was ordering 4-wide solenoid manifolds only to save on stocking multiple manifolds, and then wiring up as many solenoid valves as needed for the coach under construction. A 4-slide coach w/4 SmartBeds takes 8 solenoids for extend/retract of slides and 8 more for E/R of beds, total of 16. On my rig (only 2 slides, but 4 beds, need 12 solenoids) I had 8 solenoids on front manifold and 2 are not wired to anything. One of the 2 started to leak, so I called HWH for a plug to replace it (don't need an expensive solenoid valve just to fill the hole) and they don't make one; they only sell solenoids to fill holes on the manifold. There is another manifold on ceiling of basement; I believe (haven't checked mine yet) w/4 solenoid pairs. A 2 slide + 4 bed coach uses 12 total solenoids, 3 slide + 4 bed coach needs only 14 solenoids, a 4 slide + 4 bed coach uses all 16. If you have less than a 4-slide/4-bed coach, any extra solenoids can be replaced w/a plug. To check if you have extras, follow the wires out the back of each solenoid valve to see if the plug connector is connected to a mating wire harness; if not, Voila! you have a spare pair waiting to be (I hypothesize- begging to be) liberated and then used.

I had a machine shop use a valve end to make a plug conforming to the HWH thread/O-ring setup, and that is now installed on my manifold in the previously leaking but unused valve position. BooYah! No leak. Installs w/a 1" socket & extension after taking out the unconnected solenoid.
So if you want a plug to liberate your spare solenoid valves, I am having the machine shop make some extras. PM me for the cost & details.

Owner of an 07-40' 3-slide confirms he's got a spare HWH solenoid pair (4 beds & 3 slides = 7 slide contraptions, 14 solenoid valves, with 16 solenoid valves installed). Don't know how early in WRV's build history the OEM spare program started but it appears was before Monomoy. Might apply to Apexes w/less than 4 slides & 4 beds also.
