How to Fix a Noisy Oven - When Shaded Pole Motors go Bad

This is a short demonstration of how to replace a noisy fan caused by a seized shaded pole inductive motor in an oven. The details of how this very common motor works and its design limitations are discussed. The oven shown is a Kitchenaid Superba oven, which I believe is made by Whirlpool. However the technique shown applies to many electric fans and motors.

The other video showing how to tear down the oven to replace the thermal shutdown fuses is here

If you decide that you only need to replace the shaded pole motor, there are many options including Ebay. A classic older style design was the EM670, which may be a helpful search term if your motor has no specific markings.

This is an amateur demonstration, offered for free but with no guarantees as to safety or accuracy. Never trust any one source for critical information. Before doing any home repair, you need to decide whether you are willing to accept inherent risks that are inevitably intertwined with such repair. Any misadventure you encounter if you decide to accept those risks are your responsibility.
