we're in Texas in this cold front and I'm not ale to get the gas furnace - which has been working fine until today- to light. I have two full bottles, the indicator bubble comes up into the green , but when the heater tries to ignite, it throws the indicator back to the red zone.
getting the second bottle filled today, the propane guy said that he's had several people with rv's in and they were having heater issues also. Said that water in the propane could from inside the regulator and creaqte a small ball of ice that would bounce around until it blocked the gas, shutting the whole thing down. He said you could pour warm water on the regulator to unfreeze it. I tried this but still fo ignition.

Any quick ideas as the sun goes down ??
