Furnace help
On a short shakedown trip last weekend we had issue with furnace staying lit.
Atwood AFM model. Not sure of number as I have not removed outside access cover yet.
It lites but will go out after about 3 seconds. Lites and goes out 3 times and then has to be reset by turning off and back on. Takes about 3 times resetting before it will stay lit and function properly. After that it will run fine and restart when temp drops below thermostat setting normally!
I did turn on stove and ran that for 30 seconds or so but doesn’t seem to make a difference.
Once it lites and stays lit it functions normal.
Is there a thermocouple on these units that may need cleaning or replaced.
I know I have to clean the one on my home furnace once a year.
This is acting just like my home furnace when thermocouple needs cleaned.
Any thoughts or suggestions on what to try?
I will probably dig into it tomorrow.
It’s on a 2017 Vegas. Atwood AFM furnace.
