Micro Switch – Part Number: 3B73362F

Micro Switch

Part #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.

The fuse-time delay may also be known as a line fuse or a microwave fuse, and it is a piece for your microwave. The function of this part is to shut off the microwave if there is a power surge, in order to protect your microwave from damage. You should consider having a service technician install this part as the high-voltage capacitors in a microwave can contain a very harmful electrical charge, even when the microwave is unplugged and has been inactive for some time.

The motor is normally held in place with a retaining screw and will have two wires attached to it as well. If the motor is making a grinding noise it will need to be replaced.

Broken door micro switch. (unit does not start heating)

  • JAMES from BILLINGS, MT
  • Very Easy
  • 30 - 60 mins
  • Screw drivers
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 l eft 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.

  • Randall from ARCADIA, CA
  • A Bit Difficult
  • 1- 2 hours
  • Pliers, Screw drivers
Watched a couple of repair videos on Youtube by searching for the model number. Found out what to do in order not to get shocked by the powerful capacitor.
Ordered the two switches (To be sure, I could have ordered a third switch as suggested in the videos.)
Bought a tamper-proof star bit to get the cover off. Followed the dir ections to replace the switches. - I broke the harness and had to use some super glue, but it's all good. I should have removed the harness instead of trying to get a switch out while it was still in place.
It's all back together, and the wife is happy!!
