This microwave door 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. If your microwave will not turn or heat properly, there could be an issue with the door switch. 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.

Broken door micro switch. (unit does not start heating)
Unplug the unit before servicing. Need phillips screwdriver. Open door. Use step ladder to access and remove 2 small screws from top of the room air diffuser at top of unit. Slide diffuser slightly to the left to align the diffuser's plastic tab on the left side to rotate toward you. (The wires for the front control panel are at the far left side of this difuser, but difuser is slotted for easy removal). Once the difuser is removed you will see 1 screw at the top that secures the pannel cover on the left side of the unit. Remove screw and slide this panel slightly up and out. This exposes the plastic frame that holds the upper and lower door switches. To locate the door switches and observe how they work, close and open the door and watch the door (bayonets) open and close the micro switches. Do the (red) buttons on top of the switches move up and down when the door bayonets push and release? If the buttons do not "pop" up when opened the switch is defective. The switch frame is secured with 2 screws. Remove screws and rotate the unit out for easy access to the micro switch(s). The internal (spring?) on my unit that is suposed to allow the red (visible) button on top of the switch to "pop" up when the door is opened was broken. Carefully pry the switch outward while being careful to lift the plastic holder-piece that holds the switch in place. Be careful, there is a small pin on the frame, so rotate the switch OUT toward you while lifting (carefully) the plastic holder-piece (you will see it on top of the switch). You can use an ohm meter to test the continuity of the switches. But if the buttons don't "pop" they are defective. Replace switch and reassemble. Read more...

The relay switch may also be known as the door micro switch and is a part for your microwave. The function of this part is to monitor the door latch and communicate whether the door latch is open or closed to the electronic control board. Before making this repair, you will want to make sure to unplug your microwave and discharge the capacitor. Your microwave capacitor is able to store electricity in large quantities even after it has been unplugged. The most common reason for replacing your relay switch is if the microwave will not turn on but your timer still runs..

Timer would run but the microwave won't start
I first removed the top plate above the microwave door (3 screws), then I removed the plate containing the buttons and clock. The microwave has 3 relay switches and they are in a little holder. The holder was too difficult to remove so I just removed the bottom switch and replaced. The microwave started right up. Read more...

Installation Instructions
Jacob from Ludowici, GA
Microwave would not turn on
To determine which switch was bad, I removed all three switches from microwave. I used a D-cell battery taping two pieces of wire to the POS and NEG ends. Tape the POS end of wire to a flashlight bulb's bottom tip. Tape or twist the NEG end to the bottom of the switch. Connect another piece of wire to the top of switch and touch the side of the flashlight bulb with the other end of the wire; the bulb should come on. Depress the red button on the switch and the light should go out. The switch is good if this occurs. If light does not come on or the bulb does not got out once the red button is depressed, the switch is bad. Now you have determined which switch to order for replacement. Read more...
