Whitfield Renaissance not feeding pellets

[Maciej]

Hi! I have a Witfield Renaissance that is not feeding pellets. Bench tested the auger motor-seems fine. Bypassed pressure switch-no difference. The blower works fine. The light for the auger comes on for a fraction of a second, and the motor spins (maybe 1 rotation), but the auger does not move. The auger is not jammed. The board was rebuilt 4 years ago. Any ideas about what might be the problem? Thank you in advance.

Is the stove clean of all ash from air intake to exhaust termination?

I hope so. I cleaned the firebox and auger tube and removed the cover above the air exchanger to vacuum everything. Am I missing something that needs to be cleaned?

Re-plugged all the wires. Possibly, it was a dirty connection for the high-limit switch because it seems to be working fine again. I will go back (during daylight) and properly clean all the spade connectors. Fingers crossed.
