Used fingers to pull damaged cover away from microwave interior body. Used fingers to snap replacement cover into open slots.

Cover snap right into special slots.

Replace (after testing w/ohm meter) diode and locker holder. My door often would not close properly. Microwave let know by saying not shut properly. When disassembled found the top screw mount was hollowed out resulting in it moving on occasion when you close door. First remove casing (special safety torx head) needed for rear screws. Onc e removed all parts available to view or work on. Diode is on the capacitor so caution is needed when removing. Serious shock hazard if touched. Use insulated pliers to remove from capacitor and a phillips on the ground. Test with ohm meter Should have resistance on way and non the opposite. Replaced mine bad. Next the holder 2 phillips screws and its yours. Unplug each switch and remove. Take note to what wires go to what switch and what switch mounts where. Mine had 3 switches. Removed from old holder and put in new. Screwed holder back in place and left scrws loose till re wired. Once wired set the holder by lightly tighting the screws. Try the door till it seats properly ensuring that all 3 switches are working properly. If so thighten screws. If all seems to work as advertised, safely plug in and test unit if heats up un plug and put cover back on micro. Your all set. Happy heating.

I had a son put in the new light bulbs. Rather simple

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 went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.

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.

Easy, and the microwave still doesn't work.

After reading oven manual , used screwdriver to remove appropriate screws from behind vent. Slid vent out then cleaned vent with dish liquid. Removed old filter by simply sliding it out from easily accessed position. Inserted new filter. Replaced vent with screws. Could not have been easier, no more than fifteen minutes to complete job.Very pleased to have received replacement filter in four days.

Pro tip! Check how many bulbs you need before ordering. Mine only needed two. I got two. I suspect I’ll buy a new microwave before new bulb burns out again. Ordering/delivery was fast. No need to have spare on hand.

Unscrewed glass panel, removed old bulb, cleaned glass panel and installed new bulb. Screwed panel back into place.

i unplugged the unit,unscrewed the outer shell so that all the wiring and internal components were visible.starting at the first of three micro switches i removed the slip on terminals installed the alligator clips too the wires so the switch would now be bypassed.i made sure the wires and clips were not touching anything plugged unit in and it worked.i then installed the new switch and closed up the outer shell

Pop old one out and replaced it with new one.

Cleaned area, installed new cover secured with plastic revit.
