The temperature sensor, also known as an oven probe, helps measure the temperature within the oven cavity. If your oven is too hot, not heating evenly, has little to no heat when baking, or flashing F3/F4 error messages on your control board, you may need to replace this part. This part measures 6" long and is made of metal. Please make sure to disconnect the power to your oven range before starting this repair. This temperature sensor is a genuine OEM part.
