JNM1541DM1BB General Electric Microwave - Instructions

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

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.

I went for the cheap things first. Ohmmeter showed one of the thermostats in the magnetron compartment was open. I ordered and replaced all three thermostats. Still no heat. I took the unit off the wall (aaarrgh!) and checked the oven cavity thermal cutout. It said 7 ohms. I tested by shorting the wires together, but still no heat. So, I ordered the magnetron and diode cable. When replacing the diode cable (be sure to discharge the big cap!) either I broke it, or it was already damaged. It came off in two pieces. The new diode cable was re-enforced with thick heat shrink tubing, to prevent such breaking. You need a very short screwdriver to replace the magnetron. Now, all fixed! ~$150. A new one lists for $2000, installed in the overhead. My wife thinks I am a genius.

the problem was the mounting bracket that was installed when the house was built ,was not the bracket that came with the microwave. It was used to step the microwave out 3" in front of the other cabinets for the style that they were using then. so when I was installing the new cabinets I didn't want that style, so I ordered the original mounting bracket. It was a perfect fit and the install went great

. The part arrived in acouple of days and the repair to minutes. Good work Jim.

Replace the fuses

Ordered the part on Monday, it was delivered on Wednesday, only paid for standard shipping. All I had to do was put it in, right part, back to new!

Replaced the fuse. Result; did not fix the problem.

Once I figured out how to access the attachemnt points, the replacement was easy.

First unplugged the microwave, took top grill off, took control panel off, took wires off and used color coded tape to make sure they went back in right places, took fuse out and replaced it and put every thing back and it all worked fine and to top it off my wife did it all. So it was pretty easy.

Unpacked glass plate from cardboard box and placed atop rotating spindle inside oven - done.

bought a fuse but that didn't solve the problem. Guess I need a new microwave

Took item from sealed box and removed protective bubble wrap. Placed tray in microwave, aligning tray with turntable sprockets. Perfect fit, perfect match! And the part arrived in three days and was very competitively priced. What more is there to stay? Will use PartSelect for other replacement parts. No brainer!

Removed cover, diagnosed problem, ordered part from Parts Select, received part in 2 days, replaced part, tested and replaced oven into built in space.

Placed the new tray in the microwave.
