I looked in the back during the cool down process and found that the combustion fan wasn't running. Later when stove had cooled down more it came back on. Once it was completely cooled down I turned the fans back on and everything was good. Obviously something is causing the fan to slow/shut down once the stove gets hot. What's the best place to start for chasing electrical?
OK the thermal on the combustion blower is being tripped, please tell us all about your vent system.
Or the bearings are old and worn. My old Englander I got last year was like this. I oiled it and it helped. But in the end, there was to much play in the bearings and it would slow down or even stop a couple times. New combustion blower fixed it.
Not saying to buy a new motor, just make sure the bearings are o.k.. No freeplay or wiggle. If you spin the motor, does it "feel" o.k.?
Very possible its a thermal shutdown. Just another observation that I have had personally.
Yes that is one thing on the list. But if that blower is sucking air through crud in the stove or out through crud in the vent from the blower on out it will get very hot where it is. At 475 degrees most combustion blowers say take a hike and there goes your vacuum and pellet feed and the stove heads for shutdown.
