A direct-replacement exhaust motor gasket for select Whitfield pellet stove models. This 7" round gasket seals the joint between the exhaust blower motor housing and the combustion chamber, preventing flue gas leaks that can reduce stove efficiency and trigger nuisance shutdowns. Manufactured in the USA to OEM specifications.
Over time, exhaust motor gaskets on pellet stoves compress, crack, or burn through, allowing combustion gases to bypass the flue path. A compromised seal can cause the stove to run rich, produce excessive ash buildup near the motor housing, or trip the high-limit safety switch prematurely. Replacing this gasket at the first sign of heat discoloration, cracking, or exhaust odor near the motor is straightforward preventive maintenance.
Whitfield part 61050041 is the factory-specified gasket for this position on the covered model range. It is also catalogued under NBK Parts number 20123, a common cross-reference used by stove service technicians.

Inspect the exhaust motor gasket annually, or any time you perform exhaust blower motor service. Replace it if you notice:
Before installation, clean the motor flange and mating surface of any old gasket material, carbon deposits, or adhesive residue. Ensure both surfaces are flat and free of warping. The gasket seats dry on most Whitfield applications -- do not apply high-temp RTV unless specifically required by your model's service documentation, as sealant can make future removal more difficult.
