Broken door micro switch. (unit does not start heating)
37 of 68 people found this instruction helpful.
  • 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.

The fan cover in top of the cooking area was burned.

  • Mike from PINEY FLATS, TN
  • Really Easy
  • Less than 15 mins
  • Pliers
The original cover was burned and actually caught on fire. Research informed me that food can splatter and stick to the cover. The particle will get hot enough to ignite the plastic cover. I ordered the cover and included the fan since it was so cheap, Replacement was super easy. Done in 10 minutes and made my wife happy. She was ready to buy a new microwave because she thought something was wrong with ours but food splatter was the cause. Parts were less than $10 + $6 shipping. Keep the inside of the microwave clean!!
