Both were easy to replace. I followed the instructions in the users manual which came with the microwave. On the grease filter, I removed the 2 Phillips head screws which hold the grill plate in place. I had to open the microwave all the way to remove the grill plate. The grease filter was easy to remove and replace with a new one. I then put the grill back in and secured it with the 2 screws. Easy Peasy!

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

Take cover off microwave. Check door switches to determine which one was faulty.Remove and replace faulty switch.

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

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.

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.

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.

Easy, and the microwave still doesn't work.

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

Cleaned area, installed new cover secured with plastic revit.

removed screws from the bottom cover, installed the new motor and reinstalled the cover. The turntable is still not working. wonder if the power supply for that motor is not working. I noticed the internal microwave light glow and then burn out at about the same time as the turn table stopped working. Could that power supply provide power to both the motor and the internal light? can't find the schematics for the location of the power supply so i can test for output power.
