Door Interlock Switch Failed
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.
Very easy you just have to make sure that the tray is in the groves for the wheels :)This is the best place to shop as I have used them on all kinds of appliances and they have never let me down when it comes to price and delivery time!
glass tray cracked and broke and the rotating ring did not rotate
Easy-easy-easy...just took out the old broken tray and installed the new one. We did the same with the ring. The service from this company was excellent!! Ordered on a Saturday and received it on Tuesday....
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.
remove the glass, remove the rotating ring, install the new ring, replace the glass and my wife fixed it in 30 seconds.thanks for the providing the part.Ed
Small explosion inside unit blew out the flame sensor
Unit was painted inside recently, but apparently some paint fumes still lingered so that when the unit was turn on, there was a very small explosion that took out the flam sensor thermostat. This thermostat interrupts the white leg of the AC input and cuts off all power.Performing a continuity test on the flame sensor showed it was permanently open (no continuity). Turns out I had a similar part from an old coffee maker and when I installed this part, the microwave turned on just fine. So I order the correct sensor from Parts Select. Part installation involved removing the TT20 Security Star bits (4) and the right/left side phillips screws. Now the top/side unit cover comes off by pulling the cover backwards and up and out. The flame sensor is in the middle of the front section underneath the top cover, and comes out easily with pull-off connectors. There are also bendable pins that hold the sensor down flush to the top of the unit.
unplug the unit then pull down , lot of screws are on top. open the cover . you could see the parts that need to replace on the right hand side (heavy side). disconnect wires then test the parts that need to replace by a tester to make sure that it's really broke .then unscrew part and replace .
I went on line, put in microwave repair and watched a video on repair. I then took the oven down from over the range and took it apart. I could see were the magnetron had burned out. There was a hole with obvious burn marks. I went on line looking for the needed part. I clicked on PartSelect and order the magnetron. I received the part within three days, regular shipping. As I had not put the oven back together it took only a few moments to save 150 to 200+ dollars. I put it back together and happy, happy me, it worked.
I ordered a new one by calling the 800 number, gave them my model number and ordered a new one on the phone and paid with my credit card. It was shipped the same day and I received it on the second day by Fed-X.
Microwave Function Not Working but Speed Cook Okay
Used diagram on the web-site and a screw driver to replace the fuse and just one of the 2-Terminal Micro-Switches. When I looked at the three micro-switches one of them had a brown connector and you could see it had been burned. I just replaced that 2-Terminal Microswitch and the connector and the Fuse. Now the Microwave is working fine.
Microwave failed to head and light, fan, and turntable failed to come on.
Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.
