My Mt. Vernon ae is eight years old, and until now I have been able to fix every problem. My stove will run normally for a cycle or two--igniting and heating up to thermostat setting and shutting down. Then it will ignite and shut down with convection jammed error code. I can then unplug it, re-plug it, and the error code goes away and the stove fires up. I replaced the convection blower but it's still doing the same thing. I'm stumped. If the snap disc were bad, wouldn't the stove not fire up at all? Sure would appreciate any helpful feedback.
