Heater Not Working

I have a new 38 PFS and all has been fine the last few months. This morning I woke up early cold. A cold front came through the night before. I had the furnace running all day with no issues.

This morning when I was awaken being cold I thought the propane gas had run out. So I checked the stove and the flame was low and yellow in color. I went outside to switch the regulator over to the other bottle. Came inside and checked the stove. All good there strong blue flame.

Went back over to the thermostat, which I did not turn off or change during the bottle switch. And no furnace running. I went through the cycles, off, fan, AC, furnace and it did not kick on. I raised the temperature and still nothing. I checked the circuit breaker box and all the fuses were on.

Any ideas?

Turn off the thermostat AND remove the 15 amp fuse.
Wait a minute; plug the fuse back in and turn it back on.

When you run out of propane, the furnace has a safety system that prevents the system from running the "sparker" forever when there is no gas.

It will try to flush and light the burner just 3 times before it shuts off permanently. You need to remove power from the furnace to reset that safety system.
