Hi Guys,

It's been a while. Been using my Quad Mt. Vernon now for about nine years without any major problems, but now I might have one. I noticed this morning that the stove was not lighting, burn pot was overflowing with pellets. On further inspection I saw that the autoclean mechanism had stopped functioning. I can hear the motor turning, but the linkage mechanism does not move. I think the linkage got stuck, and something might have stripped, popped or disconnected near the motor. The linkage itself looks fine.

Is this something I should tackle myself? Anyone done this? I am pretty handy, and the soonest service call I can get is December.
 
You can see the auto clean motor sticking out on the under side of stove. Taking left panel off and removing a few things, clears the plate that is screwed over its area. Can also get at some things by removing fire pot. And you can see things by pulling the ashpan and looking in there. kap

Thanks guys,

I will take some more parts off but most of the views mentioned just show the linkage assembly, which is fine. I will have to spend some time on youtube tommorow!
 
If you put a magnet on the door sensor, it will think the door is closed and you can watch auto-clean run, to help diagnose things. I know of one guy that the hole in linkage got wore so it wouldn't work too. kap
 
Update:
Started taking things apart!
removed the autoclean mechanism, did the magnet trick (Thanks Kap). If I hold the motor lever during the autoclean sequence, I can feel the lever alternating between tight and then suddenly loose, which seems to confirm my prognosis. I think I need to get access to the motor area and see the connection, no idea how to get back there. No videos I found go that deep either. Any ideas guys? I am taking pics, so I can do a writeup when done to help others out. Thanks for any advise

As I stated in previous post, take left panel off. You will see a silver plate over motor area. You have to remove things to get at it. kap
 
How did you get such a good shot of that area?
 
Not suppose to remove chamber floor. Make sure you reseal it real good.
 
Front by window has gloss tape on it
 
Late in following up, but it turned out to be what I thought...the set screw had come loose on the linkage to the autoclean motor.

Lots of digging for a loose screw. kap
