Good morning everybody, I bought a used Harman p38 in need of work. I upgraded the circuit board to 3 knob control design with black esp probe. I also installed a new combustion blower motor & auger motor. The auger only turns on for a second or so & does not feed enough pellets to keep the burn. Could someone help me with dimswitch settings or offer advice on what i could do please? Thank you. Circuit board part #3-20-06142, black ESP probe.

Welcome....I have the same board and don't recall changing the dim switch setting. I would check door gaskets with a dollar bill, the vacuum switch, vacuum hose, or remove the 2 wires from the switch and connect them together (120Volts ), to by pass it, and see if that works.. When you put it in test mode the auger motor work OK ??

yes I have bypassed the pressure switch. No the auger does not work properly in test mode< it might turn on for a split second. Now the owner of the stove (my friend) has tried changing dim switch settings around due to frustration, and i dont remember where the factory settings were set at!
I will do that today, thanks very much for your help so far, any idea where i could find out factory settings for the dim switches?
