Harman P68 Distribution Blower

[silverfox103]

My 18 year old P68, which has given me great service over the years. As far as I can remember the only repair is replacing the heating element.

Now, I've got a little issue with the Distribution Blower. I discovered it wasn't functioning, not sure for how long. I determined it was locked, so I ordered a new one. Installed it today. Gave it a good cleaning while I was there. It's lookin good. So I fired her up and got her up to temp. The red indicator goes on for the blower, but not the fan. I ran it through all options still nothing.

Tomorrow, I will pull it down again and test for voltage. The motor is free spinning. I also have it run through a thermostat, just in case that was causing issues. I disconnected and no change. I also am a retired electrician, so that may come in handy.

An one have any tips or thoughts.

Thanks

Check the temp snap disc and hopper lid safety switch

If the light does not come on it could be the control board. Possibly the ESP probe.
