To heat a cup of coffee, user entered "10:00" instead of "1:00". Mess! After cleanup, microwave ran, but would not heat. While running, it made 2 or 3 time the noise volume as before.
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.
I'm writing because I have never in my life had such an easy time finding a part, ordering it, and receiving it! Your service is truly unbelievable. I still don't believe it and I experienced it. Nothing went wrong and it could not have been easier. Please don't go away.
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.
Glass rotating tray cracked and broke when cooking
This is the tray the glass cooking tray rest on and rotates the glass during cooking. The metal tray was installed upside down. The rotating glass tray was not properly installed. The oven was at a very high temp. and the weight of the utensil on the glass was not supported correctly. Result, big " pop " and broken glass tray. Note this is the second glass repaced. The first one dropped while removing it from the oven. It stuck to the bottom of the cooking dish and then fell to the floor. Pop, big breakage. Maybe you can learn from my mistakes.
PartSelect had helpful repair instructions on-line which made the repair easier and faster. Unfortunately, there were other problems with the oven that immediately blew the new fuse I had just installed. It was then determined that additional repair would most likely cost almost as much as a new microwave.
