Recurring Furnace Issue

Thanks, Tbirdkeys. If is stops working again, the motherboard may be the answer, but it's still working after several weeks. Fingers crossed!

In my experience Cougars have problems with propane regulators. I had exactly the same problem you describe, turned out to be a faulty propane regulator. Furnaces are your heaviest draw on propane systems. Quick test turn on 2 stove burners then try your turning on your furnace there should be little to no change in the flame on your stove, if the flame drops way down, goes out or changes to a yellow color your prop[ane regulator is either faulty or set to low. In my case the regulator adjustment scew had actually moved due to heavy vibration. I soend 90% of my time on backroads

I had the same problem with my 2018 Outback. The first time I called out mobile repairman. He removed and replaced wire connectors to the sail switch and it worked. 1 month later we were elsewhere and it failed again. I looked up part no. in owners man. and went and bought new switch. Took out old one and it was way different than one I purchased. Put old one back in and has been working fine for 2 yrs. Called Keystone after new switch was wrong and they sent me the right one for no charge. Now I have extra for next time it fails. Good luck fixing your problems.
