I came home today to my stove's burn pot not looking so good. The stirrer was not turning. I pulled the side off to inspect the motor and the motor was fine. A large diameter clinker was stuck in the burn pot and stopped the stirrer. This in turn caused the set screw to spin on the shaft of the stirrer . Cleaned everything up and tightened it all and back together. Still running like a champ. Englander makes it so easy to do maintenance.
