72183 - Instructions

I followed an old appliance repair forums post from 2008 that discussed this exact common issue with this LG model. It took me quite a while to find the info. Then I used the schematic diagrams on your website to find where the part was located inside the microwave. I removed the outer cover. I tested all components including the thermostat for continuity with a multimeter. I discovered there wasn't any continuity in the thermostat so ordered the part and replaced it. Everything works like a charm! Thanks for the great, fast service.

Un-wrapped the basket......Installed with NO tools......

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

Opened the box. Removed wrapping. Washed the new part. Unloaded old basket. Removed old basket. Set in new basket. Loaded new basket. Closed the door. Even an 80 year old can do it!

The repair was an easy replacement. The problem was the LG part was no longer available from LG or any of the other places I tried. The PartSelect customer service representative was a true professional and did an outstanding job of helping find the correct part (LG's diagram was unreadable) and cross-referenced it to find the the part that PartSelect actually had in stock. I had the part in four day. The best customer service I have had in years. I lost his name but the order was 13449146. He deserves a raise!

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

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

Removed the old one and replaced with the new.

Removed 4 screws then removed ice maker unit. Unplugged the old unit. Checked and verified the inlet tube was clean and not blocked. Plugged in the new unit. Placed unit into proper location and verified it was properly in place. Replaced the 4screws. Turned on the unit closed the ice door and it started making ice maybe an hour later by morning the ice bucket was full. Super easy.

I just popped out the broken bin and slid the new one into the slots on the door.

The fix was easy. I appreciate the expert advice on which part to purchase, as that was difficult to figure out. I received a prompt response to my question and the replacement part came quickly.

Removed ice dispenser and display with small screwdriver from front of the fridge. Pried out the whole piece slowly. This exposed the motor that activates the chute. Plugged in the new motor before any removal to verify the motor was the problem. When it worked, removed old and installed new. 3 screws. Piece of cake.

I want to preface this review by stating that I do some DIY from YouTube, but have no experience in electronic repair. The microwave is over the stove with the extendavent. First I unplugged the microwave, removed the vent and started to unscrew the microwave from the mount. I used a power drill to speed things up. I was able to remove the microwave on my own. I unscrewed the lid on the microwave and took the lid off and there is the magnetron. I opened up needle nose pliers to have each end touch the terminals of the capacitor (holds the power, Dangerous). I made sure to keep my hands on the rubber handles and avoid touching the metal part of the pliers. I used the pliers to remove the plug of the capacitor to the magnetron as well. The magnetron has 4 screws (2 top, 2 bottom). There is a magnet that can hold the screws to keep from falling but I’d still recommend a screwdriver with a magnet on the end. The magnetron has another set of wires connected by a metal bracket like a holder, not really connecting any wiring to the magnetron itself. I had to unscrew 1 screw to removed that. Adding everything back on was easy, same steps back. I plugged in the microwave and tested a cup of water before I mounted it back above the stove. Voila! I did need my wife’s help to hold the microwave on the hinge while screwing into the mount. It doesn’t take a lot of muscle for the help. $85 for the part and ~40 mins to fix a $400 microwave!

I verified I had 120 volts going into transformer when the microwave was supposed to be running. The capacitor and HV diode both tested good. Be sure to discharge the capacitor before working in this area. This isolated trouble to either the transformer or magnetron. The windings of the transformer measured good. So ordered a magnetron. It was very easy to swap. There were 4 screws and one connector. This fixed our microwave.

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.

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.
