JVM1540DM4WW General Electric Microwave - Instructions

Removed the original synchronous motor and replaced it with a new one. It turned on and rotated for about 1 day and stopped. I tested the motor for continuity and it was good. I need help in further trouble shooting.

I unplugged the appliance first. It was an over the range microwave so I only opened the front part where the buttons are, and behind it there’s a set of 3 door switches, carefully took out the burned down one and replaced it.

I used a flat screwdriver blade to push out the rivet. Then used the screwdriver to loosen the fan cover and gave it a little twist. It came out with no problem. There was some grease build up on the aluminum fan, so I cleaned it. I placed the clean fan into the new fan cover and put it back in place in the microwave. There are several notches to match up, and then I gave it a slight twist to secure the notches. Then, the new rivet was put into the hole and pushed to make it secure. Finished!

Removed top bar and control panel. Checked fuse with multimeter-it was fine. Checked bottom two door latches with multimeter-fine. Went to check top latch and discovered that the spring loaded “button” which is depressed by the door extension had lost its springiness. Ordered new one. Replaced it. Works perfectly.

Another company said the new plate would arrive in mid-March, this company seemed to be faster so ordered the tray here, and it came in less than a week. I put the turn button back in the center hole, set the wheeled ring on the bottom of the oven, fitted the new glass tray onto the turn button.

Placed the new tray into the oven.

Used Google to locate parts dealers for GE.
Ordered from Partselect.

Part arrived a few days later and I easily put it in.

I thought the cost of this part was out of line but all others sold it for about the same.

Turntable shaft was worn and out of shape likely due to heat. Simply remove rotating glass and damaged plastic shaft underneath. Replace with new shaft.

Son was able to remove the melted part and install the new one with no problem.

I followed the recommendations listed on the GE website for my model.

The cause of the fault was listed at 65% probable. I followed the suggestion, and yes it turned out the subject Interlock Door switch was my problem.

Working just fine now.

This repai me couldn’t have been simpler! I noticed that the stirrer fan cover on our microwave had melted areas. My husband suggested we just buy a new microwave. As the handywoman of the family, I searched online to see if it was a fix that I could handle. I ordered a part for less than $20 and fixed it in about 30 seconds! All I had to do was pop out the plastic screw, put the fan in the new cover, and pop it back into place!

Took control panel off . Unplug plastic protector took off old put and put new one on... very easy and quick... same alot of money by doing it mtself.

For this under cabinet wall mounted unit you will need two people to remove it. There are two mounting screws inside the bottom of cabinet. Remove the two screws and lower the cabinet. Place it on a flat surface and remove the 8 screws
From the bottom of the cabinet. Then remove the two screws from turntable motor. Reverse the procesdure and the job done. Don’t forget to turn off power. Good luck!

I opened it up, found there is sparks on the diode when cooking, I replaced the diode first, still no heat, I found all the switches and thermal stats were normal, there is 120V AC input to the transformer, so I tried to make a good guess and bought a Magnetron from Partselect, after I installed the new Magnetron, there is heat and the microwave is working.

Pulled inner panel loose, removed screws set new handle replaced the two screws.
