Propane System Issue

[David Hanvy]

Recently upon returning from a trip, I had my propane tank filled at a
FlyingJ and then left the coach in my storage building for a few days.
Today as I was packing to leave again, I find that I have no gas flow
to the inside of the coach. I can only conclude that a solenoid
activated cut-off valve is the reason. Is it possible that the propane
tank could have been over-pressured and possibly damaged the pressure
regulator ? However the gauge inside the coach reads 3/4 full as it
should. The gas detector located below the refrigerator appears to
have no power or is not working either. If anyone has any suggestions
or knows the location of the solenoid activated shut-off valve, I
would appreciate your input.
