The Hood Damper Assembly is an OEM part for GE microwave ovens. This part controls the flow of exhaust air to minimize odors and smoke from cooking. This damper opens to allow air to vent outside during microwave operation and closes to prevent outside air from entering when the microwave is not in use. Causes of a bad hood damper assembly can include mechanical failure such as a stuck or broken damper, deterioration of the linkage or springs that operate the damper, and blockage caused by grease or debris accumulation, which can impair its functionality. Symptoms of a bad Hood Damper Assembly include: Ineffective venting of smoke or cooking odors External air leakage into the microwave system Unusual noises during operation indicating a damper misalignment or obstruction This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.WB06X10436 (AP3206294) replaces 942574, AH651224, EA651224, PS651224, WB06X0388, WB06X10133, WB6X10133, WB6X10436, WB6X388.
