Microwave not turning on. All other functions operate
DISCONNECT THE POWER CORD and discharge the capacitor Leave unplugged overnight Remove vent grille by removing the 2 philips screws Remove the LED panel by removing 1 phillips screw Disconnect all connectors that plug into back of the LED board completely Remove the wires from the switches (3) at the inside edge of the microwave door Gently remove each switch housing and test all three switches for continuity Carefully replace non-functioning switches and reassemble the panel GOOD LUCK
No heat. No unusual noise. Appers to function other than no heat
Multimeter checked/confirmed switches, sensors, and fuse first. All good. High power diode was bad - Replaced. Still no heat but now loud "MMMMM" noise when running. This means either the capacitor is also bad and/or magnetron.
Remove the top of the microwave, regular phillips screws on sides, torque screws on back. Lift up back and slide off cover. Light bulb socket is easily detached and bulb unplugged and replaced. Slide cover from back lifted slightly so lip will slide into front of microwave, than replace screws. Be sure to unplug microwave before you start.
Googled problem, removed diode, checked with meter and it was open, ordered new diode, checked new diode and it read open, installed. Any way, it didn't work. Went and bought new microwave!!
After reading reviews that there was no power what so ever and a fuse replacement will solve the problem, I tried it. Replacing the fuse is very easy (and I am not handy at all). All you have to do is remove the microwave cover from the top by removing two screws, slide the cover to the left and pulling the cover off. Then remove the grill in front of you, by removing one or two screws. The fuse is in front of you, use pliers and be firm but gentle. Replacing the fuse is easy but it did not solve my problem.
Open the microwave and remove the glass turntable and rotating ring assembly. Close the door and flip the unit upside down. Remove screws that are used to attached the bottom cover of the microwave (you will not be able to remove one of them because it is a brad or some other type of screw...no worries...not necessary to remove). Remove one screw that holds the synchronous motor in place and unplug it. Plug in the new one, align it with the notch and screw hole and re-insert the screw that holds the synchronous motor in place. Re-attach the screws that hold the bottom in place and turn the unit right side up. Inserted new rotating ring assembly onto stem of new synchronous motor. Put the glass turntable back in place. Plug in the unit and wait about 15 seconds for it to get to the point where the message on the display instructs you to set the time. After you do that, you are ready to test the unit.
