LMV2053SW LG - Instructions

Unplug the unit before servicing. Need phillips screwdriver. Open door. Use step ladder to access and remove 2 small screws from top of the room air diffuser at top of unit. Slide diffuser slightly to the left to align the diffuser's plastic tab on the left side to rotate toward you. (The wires for the front control panel are at the far left side of this difuser, but difuser is slotted for easy removal). Once the difuser is removed you will see 1 screw at the top that secures the pannel cover on the left side of the unit. Remove screw and slide this panel slightly up and out. This exposes the plastic frame that holds the upper and lower door switches. To locate the door switches and observe how they work, close and open the door and watch the door (bayonets) open and close the micro switches. Do the (red) buttons on top of the switches move up and down when the door bayonets push and release? If the buttons do not "pop" up when opened the switch is defective. The switch frame is secured with 2 screws. Remove screws and rotate the unit out for easy access to the micro switch(s). The internal (spring?) on my unit that is suposed to allow the red (visible) button on top of the switch to "pop" up when the door is opened was broken. Carefully pry the switch outward while being careful to lift the plastic holder-piece that holds the switch in place. Be careful, there is a small pin on the frame, so rotate the switch OUT toward you while lifting (carefully) the plastic holder-piece (you will see it on top of the switch). You can use an ohm meter to test the continuity of the switches. But if the buttons don't "pop" they are defective. Replace switch and reassemble.

ordered on the part select web site, came quickly, order was correct

I replaced the whole component with all three switches in it even though only one switch was bad . Taking out one switch out of the holder unit would probably have damaged the unit that was holding the switches. Easy install and it works great again .

Assisted experienced and knowledgeable local repair shop technician. Had no issues during repairs. Microwave worked properly after repairs were completed.

Watched a couple of repair videos on Youtube by searching for the model number. Found out what to do in order not to get shocked by the powerful capacitor.
Ordered the two switches (To be sure, I could have ordered a third switch as suggested in the videos.)
Bought a tamper-proof star bit to get the cover off. Followed the directions to replace the switches. - I broke the harness and had to use some super glue, but it's all good. I should have removed the harness instead of trying to get a switch out while it was still in place.
It's all back together, and the wife is happy!!

diagnosed defective 'door-shut switch' in the switch holder assembly. rather than replace switch, replaced entire locker holder assembly which made for a very simple and easy repair...not to mention very inexpensive.

Unscrewed one screw that held the bulb cover over the bulb. Removed the cover, removed the bulb, inserted new bulb, replaced cover, replaced the retaining screw.

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

TOOK OUT ALL SCREWS FRONT OVER DOOR AND AROUND FRONT FRAME, LIFTED FRONT FACE OFF, FIRST CKD FUSE, BUT FUSE HAS A WHITE GLASS SO DIDNT KNOW IF IT WAS GOOD OR BAD, NEXT THING I SAW WAS THE HIGH VOLTAGE CAPACITOR, BUT CKD YOUR PRICES ON THE PARTS AND THEY WERE TWO OF THE CHEAPEST TO REPLACE, IT WAS REALLY GUESS WORK ON MY PART, SEE I USED TO WORK ON OVERHEARD CRANES IN A FACTORY, I LEARNED WHEN THEY OUIT WORKING IT WAS USALLY EITHER A FUSE OR A CAPACITOR, SO MY GUESS WORK WAS IN MY FAVOR, AND MY MICROWAVE CAME TO LIFE, I THANK YOU FOR THE NICE EMPLOYEES YOU HAVE WORKING AT PART SELECT FOR THEIR HELP AND GREAT SERVICE, DARRELL INGLE , HOUSTON TEXAS

Not knowing which of the switches to replace I ordered all three in the assembly. Replacing the full assembly was easy, first unplug the microwave. Then remove the top cover to access the screws that hold the control panel in place and let the control panel hang. There are two screws that hold the assembly in place - remove those. I used needle nose pliers to pull the wires off of the switches and immediately put the wires on to the new assembly so there was no confusion on what wire went where. Place the assembly back in position, replace the two screws to hold it in, put control panel in place and secure screws. Replace top cover and plug in.

Took old ones out, threw away and put new ones in easily.

unscrewed the bottom of the microwave and unplugged old part then took the screw out and put new one in. Super easy!

All I needed to do was replace the bulb in our microwave. But, the bulb for this unit (Kenmore Elite, which I traced to being manufactured by LG) was one I had replaced before, several times, with the closest thing I could find at the local big box stores. That bulb type matched (pin size) but wattage was a little lower which I didn't think would be a problem. However, those bulbs burned out in a month or two. So, I ordered bulbs from PartSelect that were OEMs that exactly matched the original specs. So far so good. Be aware if you are replacing a microwave bulb & are not finding an exact match at your local hardware store.

picked up turntable plate (glass), removed broken part, placed new part
in position and replaced the glass plate.

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.
