RE Furnace Model : Atwood 79 - 16 - II
On occasion, my furnace fails to fire in my '06 Bambi.
When I call for heat, the cold air starts
blowing, the igniter starts clicking, but the furnace, she a don't fire. It will attempt to fire again automatically, but when it doesn't, it seems to go into a "safe mode" ( ? ) and stop trying.
When I remove the cover looking for a reset button, I see a red light behind the circuit board flashing 3 consecutive times, pause and flash the 3 again.
Next I go to the fuse panel and remove & replace ( it's not blown ) the 20A fuse that goes to the pink wire marked Furnace / Water Pump / Heater - Range Hood ( thinking I am resetting something ) and the light then changes to a single repeated flash.
The furnace still does not try to fire however until I shut the thermostat, and then turn it on to call for heat. It usually fires on the 2nd or 3rd try. Disheartening to say the least......
Are those flashes calling out a code telling me where my problem lies ?
What next ?
