My mom's Kenmore built-in microwave oven die recently.
My understanding is that the two common causes of microwave oven failure are a blown fuse and and a failed high-temperature sensor.
Didn't see a fuse in this one, though maybe there is one way in the back, would a built-in typically have a separate fuse or just rely on the house circuit breaker like most other appliances?
I removed the temperature sensor from the top of the oven. This is the high-temp safety switch, not the food temperature sensor. Am I correct to assume that if it is functional it will be normally closed?
As they say on the net, thanks in advance.
