LMV1813SW (CW1ELGA) LG Microwave - Instructions

Both new parts were installed simply by snapping them into the holes used by the old covers. What I did need was the single round headed push pin used to hold each cover in place after they were snapped into their respective mounting holes but, none were supplied with the new covers. Luckily, I was able to secure the old pins from the damaged parts that I had held onto and used them to secure the new covers. New pins should have been supplied with the new covers.

Just snapped out the old one and snapped in the new one

purchased a new one...thank you

USE PHILLIPS HEAD SCREWDRIVER REMOVE TWO SCREWS AT TOP OF MICROWAVE. REMOVE THE OLD GRILL, CLEAN THE AREA BEHIND THE OLD GRILL AND DEGREASE THE CHARCOAL FILTER. INSTALL THE NEW GRILL VENT AND REPLACE THE SCREWS.

I received the part and my son put it in where it belonged and no problems

WHEN ARE YOU FINALLY GOING TO GET AROUND TO SENDING MY PART? HOW CAN I REPAIR THE MICROWAVE WITHOUT THE $35 PART I PURCHASED FROM YOU? PLEASE SEND MY PART IMMEDIATELY BEFORE I PHONE BBB AND JD POWERS.

Used a Motor cycle Jack to remove both unites combined. Removed side panels exposing internal working parts. Removed nonworking Magnetron and replaced it with new Magnetron. The process was completed in about 1 hour.

Needed to raise the part to match the ring. I used peanut butter to hold plastic shim while replacing to hold it in place. Built in Oct. 2009.

I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.

I want to preface this review by stating that I do some DIY from YouTube, but have no experience in electronic repair. The microwave is over the stove with the extendavent. First I unplugged the microwave, removed the vent and started to unscrew the microwave from the mount. I used a power drill to speed things up. I was able to remove the microwave on my own. I unscrewed the lid on the microwave and took the lid off and there is the magnetron. I opened up needle nose pliers to have each end touch the terminals of the capacitor (holds the power, Dangerous). I made sure to keep my hands on the rubber handles and avoid touching the metal part of the pliers. I used the pliers to remove the plug of the capacitor to the magnetron as well. The magnetron has 4 screws (2 top, 2 bottom). There is a magnet that can hold the screws to keep from falling but I’d still recommend a screwdriver with a magnet on the end. The magnetron has another set of wires connected by a metal bracket like a holder, not really connecting any wiring to the magnetron itself. I had to unscrew 1 screw to removed that. Adding everything back on was easy, same steps back. I plugged in the microwave and tested a cup of water before I mounted it back above the stove. Voila! I did need my wife’s help to hold the microwave on the hinge while screwing into the mount. It doesn’t take a lot of muscle for the help. $85 for the part and ~40 mins to fix a $400 microwave!

Pulled off band unscrewed old handle and screwed on new one replace band

Removed the phillips screws from the base.

Using a # 10 secure driver, remove the motor. (I recommend obtaining a secure star driver set to be sure you have the right size)

Replace the spacer, which is a separate part from the motor.

Reinstall the spacer and motor.

Reinstall the bottom panel.

Enjoy!

I verified I had 120 volts going into transformer when the microwave was supposed to be running. The capacitor and HV diode both tested good. Be sure to discharge the capacitor before working in this area. This isolated trouble to either the transformer or magnetron. The windings of the transformer measured good. So ordered a magnetron. It was very easy to swap. There were 4 screws and one connector. This fixed our microwave.

Just replaced the inner turn table glass tray

I opened the door and slid the tray into place.
