I am getting a loud squeek from my Englander 25pdvc. I am assuming the motor that runs on timed intervals is the upper auger, if not please let me know what is making the motorized hum. Any way the squeek begins as that motorized sound is comming to an end. The reason I am unsure if that sound is the upper auger motor is because when I looked in the hopper the auger would turn at a different time as the timed motorized sound. In other words I hear the motor and the auger is not turning, the motor stops and the the auger turns. Could the auger be spinning inside the motor? Or does the motor have a flat spot on the shaft making this impossible? This all my sound confusing but that is because I am confused at what is actually making the motorized noise at timed intervals. Thank you
