Harman P68 auger trouble

rayhough · Oct 31, 2014

I have a 6 year old Harman P68. I tried to light it this fall and all the lights looked normal but the auger would not turn. I jump the switch and the auger would turn. I blew out the line to the differential switch, replaced the differential switch, both gaskets on the ash door and fire box door. The auger still will not feed, any other things to try?
Thanks, Ray

Is the stove and vent clean? Is the combustion blower running as it should? Look at the combustion blower fan itself, is it clean? Is the auger jammed? You can pull the auger motor and see if the auger turns freely. Sound like you are not getting the airflow needed to pull in the vacuum switch, especially if it works when you bypass the vacuum switch. Hope this helps.

Verify the hopper lid seal is free of debris and closes tightly. Check the fines box cover for the same.

There must be an air leak somewhere. I even connected a tube to the differential switch and sucked just a little and the auger ran fine. I just can't find the leak.
