My microwave works but doesn’t heat, what part do I need to fix it?
For model number LMV1760ST
Hello Roberto, thank you for reaching out. If your microwave runs but doesn't heat, the most likely culprit is a faulty magnetron. The magnetron is the core component that produces the microwaves that heat your food. If it burns out, the microwave will appear to be running normally but will produce no heat. The part number is PS3517729. We hope this solves your problem!
After watching a few youtube videos, I used a phillips SD to take controll pannel off to access the switches that sense when microwave door is closed. Swapped out all 3 switched and mocrowave works like new. $20 fix (shipping included)
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.
