SCA2000BAA - Instructions

With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

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.

removed micro from cabinet, took off top piece and bottom piece, took off top and side piece to get to bulb. Removed bulb, replaced. Like someone said the engineers at GE should get an award for making an easy job very difficult.

Phillips screws out of the side; torx screws out of the bottom/back and slide the cover off of the back. The light is not visible but not hard to find: on the top left side mounted on a black plastic base with 1 phillips screw & stud holds other side. You can tell what the base looks like from the new part. GE probably wants you to call them to make the $-ha. Stay clear of any capacitors (shock) or chips (short) & touch the chassis to ground or if a tech, wear a ground strap.

Part just snapped into place and wires were reattached.

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.

It was really easy. I am not a handy person but I followed a video and got it done quite quickly. It saved me a lot of money. The local appliance repair service charges a minimum of $75 just for the visit plus parts.

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

removed broken latch connected to existing spring done in less than two minutes works better than new

Unplug power source.
Took off plastic panel partially on inside of door with door on its hinge.
Removed latch and spring.
Reinstalled new latch new spring (new part)
Reattached plastic panel to door.
Plug in power.

Easy slip in to 2 hinges

Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.

Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.
