Micro Switch
★★★★★
★★★★★
(10)
PartSelect Number PS3522738
Manufacturer Part Number 3B73362F
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.

Installation Instructions
JAMES from BILLINGS, MT
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...

(8)
PartSelect Number PS3530415
Manufacturer Part Number 6912W1Z004B
This is a light bulb and it is a part for your microwave. This bulb uses 30 watts, operates on 125 volts, and is an incandescent lamp. The function of this bulb is to illuminate the surface underneath and inside of your appliance while the door is open, and during a cooking cycle. You will need to replace this part if your door is open and the light is not activated. We recommend that you unplug your microwave and leave it inactive for some time before making this repair. Proceed with caution as the capacitors in a microwave can hold dangerous electrical charges for long periods of time even when the appliance has been unplugged.

PartSelect Number PS12713651
Manufacturer Part Number 5230W1A012E
This is a single grease filter manufactured for a microwave. The microwave grease filter filters the exhaust air and traps any grease flowing out of the appliance. It is important to keep the filter clean and intact by cleaning it regularly and replacing it when needed. A clogged air filter can cause your appliance to run inefficiently and possibly alter the taste and smell of your food. This filter is approximately 7.5 inches wide and 5 inches deep. This part is sold separately. No tools are required for this repair, the filter simply slides in and out using the easy-pull tab on the filter.

Grill Vent Broken Tabs
Piece of cake. Grill arrived quickly, was easily installed with a Phillips head screwdriver, needed for the two upper screws which most folks don't think about - Hence the need for this part, since the charcoal filter is behind the grill and most people don't think about replacing this. Easy installation of all filters. Thanks! Read more...

Vent Grille tabs snapped off
Repair was easy but you have to remove the screw at the top of the microwave (top left) in order to secure the far left tab with the hole in the tab. Place the grille in place, push to the left and then secure the screw you removed. Just remember that the mounted screw will need to be removed the next time you need access in order to replace the charcoal filter. Read more...

Manufacturer Part Number 6912W3B002K
Installation Instructions
G Michael from PORTLAND, OR
Interior bulb was burned out, turntable internal gear was stripped, and turntable ass'y wheel kept falling off
Motor was simple. Just snip out the bottom cover plate, disconnect the electrical connector, and unscrew the motor. Reverse to reinstall new motor. Rotate the cut out cover plate 180 degrees, fit tabs through slots, and screw back into place.

The bulb replacement required the side/top/side shell be removed. Only surprise was that some of the attachment screws were tamper-proof torx, so I had to buy a set of tp torx bits to take it apart. They are readily available online for < $10 for a set. They look like a standard torx bit, but with a small hole drilled into the center to accommodate the tamper-proof pin.The bulb assembly has a roughly diamond shaped attachment flange, and you need to use a screwdriver to press plastic spring tabs at each end to release the bulb.
