Myy unit had been working fine until the capacitor went. Had it replaced in November. Then, in Dec. mu unit would run, but no heat. The technician came out and said we didn't have enough gas in the propane tank. It was on 25percent. We had our tank filled, but now, sometimes the unit is running, but no heat. We have to go outside, pull the fuse out, wait @ 1 minute, the put it back in. Heats fine.

This is a Bryant unit, @ 8 yrs old.
