JVM1640SJ - Instructions

The burned remnant of the coupler was a bit difficult to remove. I did so with a pliers and also used the pliers to clear out some burned fragments of the coupler. With a flashlight I determined that the slot for the coupler was now clear. I matched the configuration of the slot with that of the new coupler and it slid immediately into place with no difficulty whatever.

picked up turntable plate (glass), removed broken part, placed new part
in position and replaced the glass plate.

Read the troubleshooting section on this site. Figured it was an interlock problem because the food was not getting hot (magentron not turning on) and the carousel was not turning. Did not think both the carousel motor and magnetron failed at same time, thus indicated an interlock problem. The interlock switches are actuated by the door latch. Replaced the assembly locker piece with all three switches (only a $20 dollar part) and microwave was fully operational again. Wife and kids think I am a hero.

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.

Removed some cosmetic panels. Removed the assembly with micro switches. Examined the faulty switch by checking the clicking action of switch. Two others were ok by this method. Replaced the switch with new one. Works fine so far. Thanks to web site and YouTube videos.

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.

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.

I had already removed the old grease filters. Unwrapped the new grease filters and popped into place. No tools were necessary.

After checking all three switches for continuity I determined that the plastic door lever had warped or gone out of wack. After shutting off power at the breaker box I removed the door, the inside trim piece around the inside of the glass. Removed the black two prong door lever, reattached the new door lever and then reinstalled the trim piece and all screws. Works fine now. Easy fix just make sure your switches are all ok then replace the door lever.

I removed the main cover ( torx security bit required) and tested the magnetron, capacitor, diode and door interlock switches according to instructions found on the internet. The capacitor and diode tested good but the magnetron looked burnt and corroded on the tip. The magnetron I received was an exact replacement for the original. It was easy to replace the magnetron which arrived in 2 days standard shipping. I also cleaned the fan while I had access to the inside area. Hoping to get another 18 years use from the microwave!

Unplugged the microwave. I opened the door. I used a butter knife to pop the bezel off the inside of the door. I pushed the locker up and to the left and used the butter knife to pry it loose. Disconnected the locker from the spring, and reversed for the installation.

Wanted to see the instructions before I install it.

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

Used Google to locate parts dealers for GE.
Ordered from Partselect.

Part arrived a few days later and I easily put it in.

I thought the cost of this part was out of line but all others sold it for about the same.

I removed the microwave from the wall and observed where the sound came from, I then removed the part that was held by two screws, then I order the part on Part Select it took three days to receive the part and in 5 minutes I installed it.
