Keep your pellet stove venting safely and efficiently with this direct-replacement exhaust (combustion) blower motor. The FAN12003 restores proper draft and combustion airflow in a wide range of Kozi, BayWin, and Winrich pellet stove models -- one of the most common service parts for these stoves.
The exhaust blower motor is the hardest-working component in any pellet stove -- it runs continuously during operation, pulling combustion gases out through the flue. When this motor slows, seizes, or fails, the stove loses draft, throws error codes, or shuts down on high-limit. The FAN12003 is the factory-spec replacement that restores full 2700 RPM output at 115V AC.
This motor ships under the Kozi part number FAN12003 and is also catalogued as NBK Parts number 20142 -- the same motor, same specs, different catalog reference. If your parts lookup returned either number, this is the correct unit.
2700 RPM matches the original motor speed required for proper combustion draft in compatible stove models.
Class B rated insulation handles sustained high-temperature operation -- appropriate for pellet stove exhaust motor duty cycles.
Runs on standard North American household current. No special wiring or adapters needed for compatible stove models.
Listed as Kozi FAN12003 and NBK 20142. Cross-referencing either number confirms this is the correct replacement unit.
This exhaust blower motor fits the following stove models. Verify your model number on the rating plate (typically located on the back or inside the door frame) before ordering.
Pellet stoves use two separate blower systems: the room air (convection) blower that circulates heated air into your living space, and the exhaust (combustion) blower that pulls air through the burn pot and pushes flue gases out the vent pipe. The FAN12003 is the exhaust/combustion blower -- not the room air blower. Make sure you are ordering the correct motor for your specific failure.
Replacing the exhaust blower motor on these Kozi, BayWin, and Winrich stoves is a common DIY service job. The motor is typically accessed from the rear or bottom panel. Disconnect power before beginning any service work.
