Quadrafire mt vernon ae it's a 2007

[zinger827]

I picked up a 2007 Qaudrafire Mt.Vernon AE it starts and runs from cold 10-20 minutes then Combustion motor just loses power?
The rest of stove has power?
Would a bad control board be the problem.
I tried another new wall controller and another new combustion motor same results?

Could be tripping out. Are you getting a fault?

No fault codes.

When I open door or hopper lid or have low fuel it shows all them on wall control so them sensors are working.
Just crazy how the motor stops getting power and just stops basically right after it's start up mode it seems?

Could be a bad connection. The motor shut not shut off. Like you say, could be the control card.

Edit - You would think you'd get a fault if you lose vacuum.
Editv-that one has two boards - you could check your voltages on the power supply board.
I guess everything is direct wired. There is no schematic ?

Power supply has 120v on ignitor side the DC side is at 15 dcv.
I also noticed today messing with it that after it gets to manual High it's pretty warmed up when it shuts down the exhaust motor the wall controller goes to ready then it will say autoclean but the autoclean moves really slow and only move about 1/8th " at a time takes forever? then says ready again and does nothing till it cools down and has been unplugged and plugged in again.

I get no error code when combustion motor stops wall control just goes to ready and does nothing.

Sounds like it thinks it's in shutdown mode. If it were in run mode, and lose vacuum that would be a fault.
I don't know much about that stove and self clean mode.
Is there another mode you can try?
