Orv,
I agree with you about the frost level showing the amount of liquid propane in the tank. That is why I don't think Jon had run out.
I have a propane heater that I heat my garage with, and sometimes the tank freezes up causing the heater to starve for fuel. If I pick the tank up and shake it around, the heater works normally for a few minutes, then back to starving. If I change tanks, the heater works normally until the new tank freezes up, by which time the previous tank has thawed, change back to the first tank, and the heater works fine again. This is why I suggested turning off the tank with the frost on it, leaving the other tank open to run the furnace. This may not be the problem at all, Jon is having, I just suggested it as a starting point.
