Hello, Quadrafire 7100 wood insert was installed in 2018. Last winter the fans randomly shut off a few times after it had been burning at temp for awhile. I took the fans out and they turn smooth as can be. When it stops it doesn't matter if I turn the switch on. It will eventually kick back on. Wouldn't think the snap disc has anything to do with it since its burning at temp when it stops and flipping the switch does nothing. It may work for a month with no issues and then the fand will randomly shut off. Any one with this stove experience this?
