LMH2235ST LG - Instructions

I removed the filter and replaced it then screwed in the the screw to hold it in

Just replaced the inner turn table glass tray

I opened the door and slid the tray into place.

replace grille and replaced charcoal filter

Simply set new tray on microwave rollers and insured glass groves fit on roller .

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

Part ordered was not at all what was expected. The part was inexpensive but with tax the cost was outrageous. I waited forever to get the part and it had nothing to do with the part I needed. When the part arrived I threw it away. It was a total waste of time and money. Extremely disappointment. All I needed was the black plastic square covering inside over the screw that holds the handle in place. While cleaning the inside of the handle the black square little piece broke. Now my handle is loose at the bottom. I have to open and close the microwave being very careful by using the top of the handle.

Originally called it "grease filter" until I found very small print "air filter" on damaged original. Part #PS3527528

Slipped into place with ease -- right bottom of microwave

Change gasket

Simple remove one screw, remove the little broken plastic and then replace the entire filter cover with the new one and tighten the one screw on the top.

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

Easy, and the microwave still doesn't work.

I UNPLUGGED the microwave and removed the cover, using a phillips and a Torx screwdriver for the machine screws. I set these screws aside, so as not to confuse them with the later encountered screws. I photographed the magnetron to assure proper placement of the 6 phillips machine screws involved in reassembly (marking the the locations on the old magnetron would do as well. I marked the old magnetron "old", to avoid later confusion. I removed the two screws holding the shields to the magnetron. I removed 3 of the 4 screws holding the magnetron to the microwave, leaving one of the top screws. I held the magnetron securely and removed the last screw, pulling out a the part of the magnetron that penetrated the microwave. I installed the new magnetron in reverse order. One problem I encountered was locating one of the six screws, which had been pulled into the old magnetron by magnetism.

very simple

Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.
