Need help trouble shooting a Ussc M/N- 5660 bay front pellet stove

Circulation fan not coming on when starting cycle is going then flame goes out. And while flame is down fan at times kicks on. The blower motor will run I have already tested.
Any input would be greatly appreciated before I spend the money on what I believe may be the circuit board being bad. Thanks

Sounds like a snap switch not working. Most stoves have one to sense when the fire is going in the appropriate time in case of a start failure or fire out to keep the feed auger from continuing to feed. And another to complete the circulation fan circuit when the stove gets to temp. Not very expensive and a fairly common issue

Thank you for the reply. Would the switch be the one at the exhaust fan/pipe , or the one that is above the circulation fan same side as the circ fan. This switch has what looks to be a reset (red) button on it . I have not had to reset this. I do have a manual but it is very vague on what switch does what function.

I would guess the switch that's on-near the exhaust is the proof of fire switch and the other controls the room fan. You could temporarily jump around it to see if that resolves your issue. Good luck
Don't attempt the jump with the stove plugged in as a oops short could fry the control board, so unplug and do the jump and plug back in. Many here have attempted to do similar while hot and have had expensive results

Thank you I will try that

The switch that has a reset is your high limit switch that shuts the stove down if there is an overheat issue. POF is by your combustion blower like bio said

Thanks for the info , I intend to try jumping the switch later on when I get home.
