JNM3163DJ3WW General Electric Microwave - Instructions

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!!

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.

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

Part Select sent the wrong part I did not realize it until prong broke off one of the bulbs. They sent 130v instead of 120v. Return bulbs awaiting resolution.

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!

Our Microwave’s Halogen Light Bulb burned out.

We looked in our manual and were able to take the cover off to get to the bulb, but we were unable to unscrew the builb and the bulb in the manual did not match the size of the one you offer (size and part number were different)

We called 1-888-738-4871.

Gentleman who answered was very knowledgeable: answered all of our questions (PULL THE OLD BULB OUT) and assisted us by ordering replacement bulbs.

We (more importantly my wife) were very pleased with the result.

change bulb

took out cover by removing cover. pulled out light bulbs replaced with new bulbs. replaced cover and tighten screw. very easy

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!

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

Unscrewed the grill, removed old filter. Inserted new filter. replaced the grill, screwed it in. The end. Oh washed the grill before replacing.

Placed the new tray in the microwave.

Inserted a kitchen knife between the cover and the inside top of the microwave. Pry out the small plastic keeper pin located in the front of the stirrer cover and save for reinstallation. Twist the cover and gently remove. Remove the metal fan and insert it in the new cover. Reinstall the cover and twist to align the hole for the keeper pin. Reinstall the keeper pin and push the cover and pin up tight against the inside of the microwave.
