The other night smelt burning plastic. set off smoke detectors. Killed the stove aired out the room.
Now if I power the stove on both blowers run auger motor does nothing. Also it's not going through the test
mode when I go from off to on. Have the unit ripped apart I don't see any damage to the board. But I'm not going
to remove all the wires until I have a replacement. Anybody think there could be something else other than the circuit board?
 
How does the auger motor look/smell. Does it turn freely, and have you tried jumping power to it to see if it isnt whats cooked?
 
doesn't smell. moves freely. Didn't jumper it. Dealer had the board. Thought I would have to order it and wait a week.
 
It wasn't the circuit board. So i jumped the auger motor it works fine. need to see a schematic
 
I bypassed the low pressure switch same symptoms. Disconnected the esp probe. jumped the connector. Auger ran.
I'm thinking now maybe a piece of bag fell in the hopper got pushed through the auger. caused the smoke higher heat
of burning plastic took out probe. Probe still might be good. Think I will replace any way. Anyone know what the low pressure sensor is for?
Maybe keeps the auger from running if the door is open
 
cleaned sensor with steal wool. Have it on Turbo right now My basement is getting warm. Tomorrow get to clean the advance.
