SCA1001KSS LG Microwave - Instructions

Turned out the issue was easily solved by replacing a single, inexpensive fuse.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

Turned of f the circuit breaker to the microwave. Unscrewed the cover (1 screw!) popped out the old bulbs and plugged in the new ones, using the bubblewrap as a handle to be sure my skin didn't touch the light bulbs so the oil from my hands didn't damage or shorten the life of the new bulbs. Turned the circuit back on. That's it!

Unscrewed the light cover beneath the microwave with a phillips head screwdriver. The bulb is very tiny and has 2 straight parallel prongs that slide into 2 small holes. Grab bulb from both sides with each hand firmly and slide STRAIGHT out (no twisting or pushing). Don't worry about breaking even though it may take a fair amount of pressure to pull out. New bulb arrived within a couple of days. Due to high shipping cost, suggest buying 2 or more bulbs at once. Bulb is often used as a kitchen night light so that is probably why I only got 9 months out of it.

The old fuse is perfectly good. The new ones arrived within a day.

Well first of all I thought I ordered the wrong light so I called and ordered the Halogen light. When the Light came in I went to change it out and realized the first bulb I ordered was the correct one. The Parts select customer service was extremely helpful and made my mistake easily resolved. At any rate, changing the bulb was a piece of cake! Just unscrew the plate (1 screw) and take out the old bulb screw in the new one. Presto, it was done. However my glass cover plate for the light somehow broke, so I ordered a new one with the help of customer service. I replaced the plate which only took about 5 mins. To replace the plate you just unscrew the one screw and on the metal frame the glass plate sits on a metal frame which has prongs that you pullup and then slide the glass out. Once the glass is out you slide the new one up and push down the prongs. Lift the frame back up and screw it in.

1. turned off electricity -- unplugged the unit 2. removed 3 screws on top of top vent, removed vent screen then I located the little white cylindrical fuse and popped it out with a table knife. Then I popped in the new fuse. Replaced the vent screen and screws -- plugged in the appliance and it is working again.

Unplug the unit before servicing. Need phillips screwdriver. Open door. Use step ladder to access and remove 2 small screws from top of the room air diffuser at top of unit. Slide diffuser slightly to the left to align the diffuser's plastic tab on the left side to rotate toward you. (The wires for the front control panel are at the far left side of this difuser, but difuser is slotted for easy removal). Once the difuser is removed you will see 1 screw at the top that secures the pannel cover on the left side of the unit. Remove screw and slide this panel slightly up and out. This exposes the plastic frame that holds the upper and lower door switches. To locate the door switches and observe how they work, close and open the door and watch the door (bayonets) open and close the micro switches. Do the (red) buttons on top of the switches move up and down when the door bayonets push and release? If the buttons do not "pop" up when opened the switch is defective. The switch frame is secured with 2 screws. Remove screws and rotate the unit out for easy access to the micro switch(s). The internal (spring?) on my unit that is suposed to allow the red (visible) button on top of the switch to "pop" up when the door is opened was broken. Carefully pry the switch outward while being careful to lift the plastic holder-piece that holds the switch in place. Be careful, there is a small pin on the frame, so rotate the switch OUT toward you while lifting (carefully) the plastic holder-piece (you will see it on top of the switch). You can use an ohm meter to test the continuity of the switches. But if the buttons don't "pop" they are defective. Replace switch and reassemble.

This is the second time that this lamp hase gone out. It is located in a small space in the top of the microwave and you need to remove the top front pannel, then take a screw or two out of a metal shield and bend the shield up to get your hand into the compartment where, if you know how, you can reach in and lift out the reflector shield that the lighbulb is plugged into and remove the old one and plug in the new one. The first time was hard to figure out how to do it but the second time wasn't bad because I knew how to do it.

*Remove Two Phillips head screws from the top of vent slide the vent left to remove it. Take the charcoal filter out then the metal cover underneath the filter. It also has a phillips head screw. bulb socket is on right facing down. Squeeze the metal clips and remove socket from bracket. Installation is the reverse of removal.

After removing the screws holding the 2 cover plates in position, I removed the halogen light bulbs with my fingers. Then I placed a paper towel around the first replacement bulb and lined up the two wire connectors with the two holes in the receptacle. I pushed in, but the bulb's probes did not slide into the receptacle. I spent five minutes aligning and pushing but to no avail. Then I removed the filter screen on the side of the receptacle, shined a flashlight beam on the receptacle, and with an improved view of the two holes in the receptacle, slid the bulb in. The second bulb was inserted in a few minutes, and the job was done. Whoever designed the halogen bulb was not as bright as Thomas Edison.

This did not fix my problem. I've ordered a new microwave.

Had to remove microwave from the wall. Then disassemble entire top assembly to get to the part. Easy enough to replace after that. Then just reassemble and reinstall. About 2hrs. total

Went to onlin source, found a couple youtube videos then went to the GE site which had a not-too-easy that find trouble shooting guide. It was extremely helpful as it described a fuse as a fix 80% of the time for touch paid failure. I really didn't believe it would b a fuse, but it was the cheapest fix, $8. I got the fuse and was surprised to fine there are two of them on this model. I took a guess and replaced the top one ( neither fuse was black or burned to indicate a failure but the top one was a bit mor greyish). put it all back together and it works fine.

took off upper grille and touch pad and removed the old line fuse and replaced with a new fuse ...turned on it is working fine...sources of help: UTube and GE manuel

Remove microwave and set on flat surface. Remove all screws on top. Remove all screws around back edge holding top on. Finally remove the screws on botton holding top on and remove top. On left side on top, remove 6 screws holding black channel in place. Also remove 3 screws holding metal top in place. Now lift black channel up and unplug 2 wires on cutout. Replace cutout and reinstall everything in reverse order. Worst part is taking microwave down and reinstalling.
