I have a 2006 Mt Vernon (not AE) that is consistently shutting down after about 20 - 25 minutes of operation. It will start (often requires 'reset') , exhaust blower runs, fire starts up, it warms up, convection blower kicks on then the unit will shut down after short period. It appears the auger stops feeding?
I jumped the vacuum switch (no effect), pulled auger to ensure it is not jammed and cleaned everything top to bottom. Problem persists.
Some information suggests snap disc replacement needed or control box replacement.
Any troubleshooting tips and/or suggestions as to next steps are greatly appreciated.
