Harman Exhaust Fan Blade (5" Single Paddle): 3-20-40985-OEM
This 5" combustion blower fan blade is a single-sided impeller used on the Harman Accentra-Cast, Invincible Insert, and the PC45.
If any of the petals (fins) are bent, your stove may vibrate. To fix this, you can sometimes bend them back to help balance the motor. It is suggested to replace the impeller if the metal is corroded, if there is metal missing or if the impeller is unbalanced through wear and tear.
If you are replacing your combustion blower motor for any reason, it is suggested to also replace the impeller. Impellers are made in 3 different sizes which is why they are not included with the combustion blower motors.
