Faulty Propane Gauge?
Went to a camp site this weekend and the temperature dropped into the low 20s. I have two 30 lb tanks. One was somewhat used up already and the other was still full and unused. We emptied the low tank.
I switched the regulator over to the full tank I couldn't get it do do anything. I opened the tank very slowly so I don't think it was the safety feature kicking in to restrict the flow.
I do have gauges that show the level of the tanks. Those happen to not be all that functional. They really just go from "green" to "red" very quickly and frankly you could just pick up the tank to identify "empty" without a gauge. The full tank was showing "red" as if empty. I closed the tank, removed the gauge, reconnected my propane line, and then slowly opened the full tank again. This time, my stove and fridge had no issue turning on.
Question --- Should I assume that the not so useful gauge also managed to somehow freeze up in some way such that I couldn't get anything out of the full tank? It seems to be the thing that was stopping the flow because 1) it was reading empty and 2) once I removed it from the equation the tank worked fine. BUT... how does that happen? Propane doesn't really freeze unless the temperature drops below the coldest of ice age temps. Some frozen water vapor / moisture in the gauge somehow??? Could that have been the issue?
I'm back to working normally but just trying to understand what could really have caused the problem.
