I have a PB820FB. It is aprox 3 years old. The auger will not feed pellets. I took it apart and the auger is clean and not jammed. I ordered a new motor and installed it. When I turned it on the large fan came on and what pellets that were in the burn chamber ignited and it started to smoke. But the motor did not start up and attempt to turn the auger. Could the control board be bad? Should I check the voltage to the motor? Thanks for any help. Hopping to have it working for Thanksgiving.
