Hello,

I am looking for help with my Harman P38 control board upgrade. I bought it a year ago and I am finally getting to install it and I am hung up on the wiring to the feeder/auger motor.

I went to install the upgrade kit and I am stuck when it comes to the wiring for the feeder auger motor along with the low pressure switch.

The new wiring has a female crimp connector on the white wire at pin 6, trying to connect this to the white wire going to the feeder auger motor will not connect because the crimp on connector is also a female crimp on connector on the cable coming from the feeder auger motor.

I have the wiring diagram.
I also don't know if I need to use the optional Blue Jumper for the pressure switch.

Does anyone know if there is a video of installing the wiring. I have everything else wired except for the auger and the pressure switch.

Thank you
 
Hello, just sending an update.
I talked to the Harman dealer in Brookline NH (Stove Keepers) where I purchased the stove. They were very helpful. I was correct the black and the white AC wires going to the pressure switch and the auger didn't matter which way they were wired. One power wire goes to the pressure switch and the other power wire goes to the auger/feeder motor.

The other issue that I saw was that the crimp on connector coming off of pin 6 of the board did need to be changed from a female to a male connector. The technician at the dealer said he ran into that many times.

Thank you,
Frank
