Micro Switch

Part #6600W1K001D
The door switch, often referred to as a primary interlock switch, provides power to the various components in the microwave when the door is in a closed position, and interrupts power when the door is open. This door switch is approximately 1 1/2 inches long, and has 2 metal prongs called terminals that extend from its body. Common symptoms related to a faulty primary door switch include: microwave will not turn/shut off, or the microwave will not heat properly. You can check the switch for continuity using a multi-meter. With the actuator button depressed, you should see continuity between these terminals. If there is no continuity the switch will need to be replaced. NOTE: Before you begin this repair, first make sure your microwave is unplugged, and that your capacitor is discharged. A capacitor stores large amounts of electricity even when your microwave is unplugged.

Part #6549W1S011B
This AC synchronous motor is a genuine OEM replacement part specially made for microwaves. It operates on an alternating current, and it is responsible for rotating the turntable to ensure even heating of your food. The motor can fail due to physical damage or malfunctioning internal components such as the bearings. If your turntable is not rotating, you will need to replace the motor. You can find it underneath the microwave cavity, near the center. Disconnect the microwave from the power source and remove the cover. Turn the microwave over and remove the bottom panel to access the motor. Disconnect the motor from its mounting location, and then insert the new motor in its place. Ensure the new motor is securely attached before reassembling the appliance.

Part #6912W3B002K
This incandescent lamp is sourced from the original manufacturer, for use in microwaves and ovens. It illuminates the interior of the appliance cavity allowing you to view the food as it cooks or heats. It is typically located behind a panel or a cover inside the microwave/oven. Like any light bulb, the lamp can simply burn out over time. However, it is also possible that the lamp socket or wiring may be damaged resulting in an electrical failure. Before beginning any replacement, ensure that the appliance is unplugged. Remove the old lamp from its socket and inspect the assembly to ensure it is in good condition. Insert the new lamp in the socket and make sure it is seated correctly before repositioning the panel/cover. Plug the appliance back in to verify that the new lamp is functioning.

My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No tri p to home depot today.
