Thanks. Put the tank back in the rack and sloooowly opened the valves. Seems to be working. Switched the auto valve left and right and seems to work in both positions.
What would cause the automatic valve to shut down after working for two weeks? My gas usage has been for the refrigerator (Or, does it operate on electric when in a full service camp site?), hot water heater and occasionally, the oven. I use a 1500w ceramic heater to keep the trailer warm at night, so no furnace and no gas for the furnace.
Thanks again.
