JES1033WB - Instructions

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.

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.

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

I went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.

To remove the outer cover of the microwave you have to unscrew 7 or 8 Phillips screws but most of them have "secure" type heads, so you need a driver with a hole in the middle, to fit over the pin on the screw head. I had one of those already, so it wasn't a problem. The metal cover is slid between rubberized strips on the front face of the enclosure and needs to be lifted and tugged out quite firmly in order to release it. Once the cover was removed, the bulb can be seen attached to the main frame of the microwave by a soft metal lug that can be bent back by hand to release the bulb and its integrated holder. The wiring harness simply pulls off of the bulb prongs and there you have the charred remains of the original bulb! I tried every appliance store and hardware store in Bismarck, but nobody had this part. When I typed in the serial number on the bulb, Partselect's site came up with exactly what I needed. Replacement was a simple reversal of the process, making sure not to over-tighten the sheet metal screws on the cabinet. Voila! We have light beams again. Thanks Partselect.

removed the outer case - this was the most difficult part because the microwave is large, heavy, and cumbersome.
once the outer case was off, it was simple - easy to see where the old part was and the replacement was an exact match
it was then just a matter of disconnecting the old burned out part and replacing it with the new one
then wrestling the outer cover back into place and re-fitting the screws.
Microwave is fine now and hopefully good for another 10 years!

get microwave out of cabinet. Took two people because it was very heavy. Used special hex drive socekt because of dimple in the female nut.

unplug oven from power
remove glass turntable
remove cabinet housing
remove burnt out bulb
order correct part
reinstall new bulb
reattach cabinet housing
install glass turntable
plug into power outlet
confirm light bulb on

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.

DISCONNECT THE POWER CORD and discharge the capacitor
Leave unplugged overnight
Remove vent grille by removing the 2 philips screws
Remove the LED panel by removing 1 phillips screw
Disconnect all connectors that plug into back of the LED board completely
Remove the wires from the switches (3) at the inside edge of the microwave door
Gently remove each switch housing and test all three switches for continuity
Carefully replace non-functioning switches and reassemble the panel
GOOD LUCK

I removed the broken wheel and replaced it with the new one. No tools or assembly needed. Took about 30 seconds. The part arrived in about 2 days.

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

-unplug
-remove top and front covers
-unplug wire connectors from heating assembly
-remove heating assembly from metal stand and push out of the way
-remove metal stand from dry
-pull out heating assembly
-install new one in reserve order

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.
