My 30" Kitchenaid oven blower is excessively noisy. Likely the blower? or is the mounting loose? Is there a history of bearing failures or imbalance in Part Number 4449888 (AP3109908)?
ANSWER Madcir, Like any motor, the more usage they encounter the noisier they get. In most cases, the fan gets noisy due to mishandling and or improper installation, and this occurrs fairly early in the usage. Your issue is most likely due to age and usage, When you replace the assembly, make sure you use the foam pad(s) and the fan assembly is installed level in both directions and the mounting screws are not overtightenned. Thanks
