My 2008 Classic Bay started making a godawful clicking noise from the feed motor housing, then decided to stop feeding pellets. I have opened it up and made sure there was no pellet blockage in the auger, etc. Checked the snap discs - okay. When the stove is turned on, the exhaust blower starts up, the pellet red light on the control box comes on, the fan speeds up, but no pellets drop into the hopper. The auger does not turn. Am I correct in assuming that the auger motor has burned out and needs replacement?
