AH combustion air motor replacement - Pluto - 05-23-2025

Hello all,

Our AH has been getting louder during operation, so I decided to replace the bearings using a 5 year rebuild kit for the burner that I found on heatmyrv.com.

I've gotten everything apart and the bearings are nice and smooth but the combustion air motor is very "notchy" when I spin it. 

My first instinct is to replace the motor, but I wanted to double check with you all first.

The shaft on the motor turns fine, but feels like I'm turning a knob that has a detent for different positions.  Idk I'd that makes any sense but I don't think it should feel like that.

Thanks!

Tyler Phillips

I went ahead and replaced the bearings and other parts that came with the rebuild kit.  I'm probably going to order the motor before putting the burner back in.
