The Microwave was completely dead and wouldn't run, light up or anything.
I followed an old appliance repair forums post from 2008 that discussed this exact common issue with this LG model. It took me quite a while to find the info. Then I used the schematic diagrams on your website to find where the part was located inside the microwave. I removed the outer cover. I tested all components including the thermostat for continuity with a multimeter. I discovered there wasn't any continuity in the thermostat so ordered the part and replaced it. Everything works like a charm! Thanks for the great, fast service.
I had broken the clips that hold the vent in while cleaning it.
I ordered the part from this site (which was a little lower cost than another site but was described as a genuine GE part), and I looked up the instructions in my manual. It took about a week to get the new grille. There are 2 philips head screws attaching the grille. Just remove the screws, discard the old grille and put in the new grille with the same screws. The description on-line calls it a snap on grill which is a little misleading. It is attached with screws. I was fearful that it would not fit but it is identical to the old one. I am very pleased I did not have to replace the microwave even though it is 11 years old, it works.
I removed the main cover ( torx security bit required) and tested the magnetron, capacitor, diode and door interlock switches according to instructions found on the internet. The capacitor and diode tested good but the magnetron looked burnt and corroded on the tip. The magnetron I received was an exact replacement for the original. It was easy to replace the magnetron which arrived in 2 days standard shipping. I also cleaned the fan while I had access to the inside area. Hoping to get another 18 years use from the microwave!
Unplugged the microwave. I opened the door. I used a butter knife to pop the bezel off the inside of the door. I pushed the locker up and to the left and used the butter knife to pry it loose. Disconnected the locker from the spring, and reversed for the installation.
Microwave door would not shut completely and would not activate switches
After checking all three switches for continuity I determined that the plastic door lever had warped or gone out of wack. After shutting off power at the breaker box I removed the door, the inside trim piece around the inside of the glass. Removed the black two prong door lever, reattached the new door lever and then reinstalled the trim piece and all screws. Works fine now. Easy fix just make sure your switches are all ok then replace the door lever.
Frost build up on bottom to ice bin and delivery chute in door creating ice blockage
Remove the ice bin. Turn the ice maker selection to "OFF" Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one. Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug) Move the selector from "OFF" to "ON" Replace the ice bin and close the freezer door
The Microwave was making a loud sound when the vent was turned-on
I removed the microwave from the wall and observed where the sound came from, I then removed the part that was held by two screws, then I order the part on Part Select it took three days to receive the part and in 5 minutes I installed it.
When removing a non-working door switch, you will see a hooked piece of plastic on the holder locker that looks like a latch. If you try to pull it back in order to either remove the bad switch or install a good one, it will likely break. Instead, you need to pivot the switch (It pivots on a little post which is fitted into a hole at the corner of the switch) out of position so that it is not held back by the 'latch'. Then lift the switch out. If you have to use lots of force anything, you're doing something wrong. Reverse all this when installing the new switch.
