JES735WD - Instructions

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.

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

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.

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.

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

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.

Part just snapped into place and wires were reattached.

Removed outer cover, Cash with for Phillips screws as I recall, Then remove six or eight safety screws with Phillips special bit. Pulled bulb, cover back, removed, and replace bulb, back together all set

I used a phillips screw driver and a special type bit to undo the screws from the cabinet and found the light bulb and took the old one out and put the new one in and put it back together.

tested cap. with ohm meter which showed a short. A new HV cap., a fuse and it is working fine again.

I assumed light was burned out and got a replacement bulb.
Removed back and side screws with slight difficulity.
Was not able to remove cover. The top front would not loosen. I tried every trick in my 80 year repertoire. I gave up and put it back together.
I emailed PartSelect last week explaining the problem. So far no reply.
I am sure I have the right model # and others seem to have little trouble removing the cover.
I paid $85 + tax for the oven and it has worked well for about 8(?) years.
From what I read here, I figured I could handle the bulb replacement.
I'm just out the cost of the bulb and shipping and the oven still works. It would have been nice to have the light work again but we will just wait until it quits working and buy another inexpensive unit.

unplugged power
removed main black cover.
located part WB24X10047 and replaced

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
