ACO1860AC - Instructions

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

Lifted out old support put new one in. Fixed in less than 30 sec.

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.

well I unplugged the microwave one day prior to working on it. shock precaution smart way to do this job. very easy pullout the screws behind the unit pull off the outer casing. minor screws inside the unit you have to remove a couple things out of the way. unplug the magnetron and remove first gives you more room to work on the side panel to replace the micro switches. I only replaced one the bottom micro switch. only one bad, but since I was in there I clean the bulb and changed the magnetron any ways. I read other reviews and made my choice to do so. it works perfectly now. Thanks PartSelect for having parts.

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.

Turn off power supply at breaker . Replace old bulb with new bulb .

screwed in new bulb

removed old covers which were cracked and dirty.
the repair part looked exactly like the original but did not fit correctly. i had to do some changing of the size to make it fit. it does not clip in place as it should but we are living with it as it does cover the light bulb. the grease filter is perfect

I thought that if I went one more time to visit my son, and the microwave tray was still gone (due to their having broken it), I would just order the part MYSELF!! So, that is what I had to do. They have been without this for at least 3-4 months........ Well, it was sitting at my door in less than 48 hours after I ordered it! Easy, easy, easy..........thank you!

Microwave vented up toward the ceiling discoloring it. I positioned the charcoal filter over the vent holding it in place with scotch tape. It keeps the ceiling clean and dose not affect air flow from the exhaust vent. I change the filter every year.

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

Access is via RT. SIDE Panel as you face microwave. There are three screws on the bottom right edge to loosen. After that the side panel slips down and off. the fuse is located in the rear near where the power cord comes in. It is the white ceramic tube 1/4" in dia. and 1-1/2" long. Pull it out like any fuse and replace with new one. Reassemble and you are done!

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.

Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together
