Help - Harman Accentra Insert combustion blower

[Steve T]

I have an accentra insert that I cleaned today. When I went to restart it, the combustion blower spun for a second and then started to hum without turning like it was blocked. I pulled the unit out and can see the fan blades which are moving freely. I fired it up for a second and they moved and then the blower started to hum again and the stopped moving. Any thoughts on fixing this?

Try the Test mode and see if you get any status blinks on the LED.

The combustion light comes on and stays lit in test

Well I'm stumped too but then I'm no expert. The next thing I would be inclined to try is to hook up the combustion blower to a set of 120V test leads to see if it operates independent of the stove electronics.

Hopefully, one of the guru's will jump in and offer better advice.

Did you try wiring the blower directly to 120 Volts? Or, if you have a multi-meter, measure the voltage at the blower when it should be running.
