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.
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.
Removed cover, diagnosed problem, ordered part from Parts Select, received part in 2 days, replaced part, tested and replaced oven into built in space.
When trying to run, intermittently, the light would come on but the tray wouldn't rotate or cook. When the door was open, the tray would intermittently rotate.
I pulled out the unit and found 2 interlock switches that are depressed when the door closes. After cycling the door open/closed I found that one of the switches occasionally would stay depressed. The repair was easy (after I took off the panels so I could get to the switch) I simply removed 2 screws that attached the interlock switch assemblies to the main unit. Then I popped out the defective switch and popped in the new one. This did indeed fix my problem.
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.
Microwave would only heat food items to a warm condition
Removed microwave cover using screwdriver and anti tamper bit available at local hardware store. Megnetron had broken magnet making discovery of deffective part easy. Removed wire connector and three screws attaching magnetron to case, removed magnetron and installed new item in reverse order. Installed cover and made popcorn for operational check of microwave. Happy days..........
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.
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.
Timer, light and control pad worked. Turn table and heat did not work. Oven would not start up.
I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.
