propane switch problem

[bandmbrown]

over the past week or so i have posted several questions concerning a propane problem with our coach. originally thought it was air in the line...then bad propane. but now i got it figured out.
it's the on/off switch located next to the fill valve.
turn it on/off/on and i get propane under pressure and everything works great.
after a few minutes the pressure is turned off. go mess with the switch and it happens all over again.
i guess i have a switch problem...or could it be what the switch attaches to.
i'm not really sure how this whole thing is rigged.
thanks

a little research indicates the switch is attached to a electric solenoid valve that turns the propane on/off remotely.
anybody ever have to replace one.
thanks

Believe that is some cases that switch is tied to a leak detector to shut down. Would check to see if that is the case or if it is just a safety type item manual operated

That solenoid valve is part of the older style LP detector system, tht required the detector to shut off propane if its sensed a leak. You can get replacement valves, e.g. at PPL Motorhomes Part Dept.

Or you could remove it - they are no longer required by the fire code.

Check your LEAK DETECTOR RE-SET SWITCH, it should be located inside the motorhome. Just last week I wanted to run my (2) furnaces before winter to make sure they were in good order, and neither would lite. I could hear the fuel valve activating but no flame. I then checked the stove for possible air lock, and it would not lite. As the last resort, the water heater would not lite either, telling me there was no gas flow. I then re-set the detector swith and WALLA, everything is normal. Ours is located close to the floor in the kitchen area, just a good safety item. Good luck, Happy trails & travel safe.
