LMV1813SW (CWHELGA) LG Microwave - Instructions

Removed the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

Read the troubleshooting section on this site. Figured it was an interlock problem because the food was not getting hot (magentron not turning on) and the carousel was not turning. Did not think both the carousel motor and magnetron failed at same time, thus indicated an interlock problem. The interlock switches are actuated by the door latch. Replaced the assembly locker piece with all three switches (only a $20 dollar part) and microwave was fully operational again. Wife and kids think I am a hero.

Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.

Removed outer cover

removed lower door switch

installed new switch

Wa La!

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

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

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.

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.

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.

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!
