Parts arrived, and I installed new 'Thermocouple and Cover' and stove having same behavior. FYI, Thermocouple is positioned extending about 1" over the burn-pot, and the Thermocouple is touching the inside end of the ceramic cover.
Stove starts up, pellets drops, ignitor lights pellets in the pot, but then pellets STOP dropping. Fire goes out and stove shuts down. Whole cycle takes less than 10 minutes. Again, this Mt Vernon is a very 'early' OE model and has NO trouble-shooting lights at all, so working in the blind !
Again, I have replaced Snap Disc #2 that controls the On/Off to the feed system. The red Reset button on this Snap Disc never tripped, so it appears to be working fine. FYI, the Convection blower never came on. I removed and checked the Vacuum switch 'hose' and it was clear no obstructions !
Confused now on next steps to trouble-shoot, and very concerned that the issue may be related to the control box ?
Any feed-back will be greatly appreciated !
