The Whitfield 12056010 is a direct-replacement exhaust combustion blower motor engineered for select Blaze King and Whitfield pellet stoves. Running at 3000 RPM on 115V/60 Hz, this motor maintains the precise draft and combustion airflow your stove needs to run cleanly and efficiently. If your stove is shutting down on high-limit errors, producing excess smoke, or the combustion blower is noisy or seized, this is the motor to replace it with. Also cross-referenced as NBK Parts 20137.
The exhaust combustion blower is one of the most critical components in a pellet stove. It pulls combustion gases out of the burn pot and exhausts them through the flue, maintaining the negative pressure that keeps smoke from entering your living space. When this motor fails or weakens, the stove's control board will typically trigger a fault or shutdown to protect against backdrafting.
The Whitfield 12056010 restores factory airflow performance to the combustion chamber. It is a Class B insulation-rated motor designed for the thermal environment of a pellet stove exhaust path, and it draws only 0.29 amps -- consistent with the original specification for these model families.
Designed to swap directly into compatible Blaze King and Whitfield stoves. No modification required on supported models.
Rated for the elevated temperatures typical of pellet stove exhaust blower service. Built to last in sustained high-heat operation.
Matches the factory motor spec for proper combustion draft and exhaust evacuation on supported stove models.
Also sold under NBK Parts number 20137, making sourcing and verification straightforward for service technicians.

Common symptoms that point to a failed or failing combustion blower motor include:
Before replacing the motor, confirm the exhaust path and flue are clear of ash buildup and obstruction. A restricted flue can cause the same fault codes without any motor failure.
