furnace ignites heat for 5 min then only fan
This happened once in the early spring and again on the last trip.
I set the thermostat to heat and auto set the temp. The furnace turns on and ignites. The furnace stays on and we get heat for about 5 minutes then the furnace shuts down and the fan continues to run with no heat. Turn off thermostat and back on and the same thing occurs.
I have good airflow and tried some other trouble shooting steps I found good propane flow to all other areas. stoves and water heater, with good constant flame. So far it worked to fix the problem both times if I shut off the furnace, unplug shore power and disconnect the batter. Reconnect everything fire it up and again so far this fixed the problem and it functioned as it should.
Anyone have this problem, know how to fix it the right way?
