Hi, new to the forum and impressed by all the advice I see here! I have an 8yo Accentra insert. It worked fine until this year, and I clean it annually (use about 1ton/year). Now the auger won't turn when I try to start it up, but all the motors (including the auger) work fine when I go into test mode. I tried bypassing the pressure sensor, with no luck. I read that another cause of this would be the hopper lid switch, but for the life of me I can't find such a device on the stove. Any suggestions for how to debug this?
