My microwave was running for about 5 min, doing a baked potato, and when it was finished it lost power. The outlet has power so its definately the microwave. I listed the microwave model number above and through my research I think its something in the control board. I thought it was a fuse problem but I dont see any fuses listed in the parts manual.
Answer Hello Pauly,
Be absolutely sure to unplug the unit as the component you are accessing has 120Vac supplied to it, even on one side if the part is bad.
The problem will be the cavity thermostat WB27X10909. If you remove two screws along the top edge of the unit, you will be able to shift the grille to the left. This will enable you to remove the grille and access the inside of the unit. If I recall correctly, there are two black wires leading to the cavity thermostat, which will be clipped into a retainer which holds the thermostat against the outside of the cavity. It is important to get the new thermostat back into this configuration to prevent a situation that could cause fire. Also, I must mention that most people want to bypass this thermostat so they can use the unit while waiting for the part. I have to interject that if this is done, you are endangering not only the other high dollar components inside this unit, but the chance of a fire is increased substantially. Do not bypass this thermostat for you own safety!
