PSB2200NWW01 General Electric 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.

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.

Unpluged power cord!! Removed front control panel to expose electronics (need to remove top horizontal vent cover to expose mounting hardware). Unplugged leads to control panel board. Removed magnetron with Tstat (3- phillip heads, need stubby). Installed new parts and control panel, plugged it in tested. Done.

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

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.

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

First and most important - unplug AC power 24 hours before service.

I removed the vent cover above the main door, then I removed the screw which holds the control panel in place, unplugged the main connector on the control panel so I would have enough room to work, removed grounding screw from the DIODE ASSY, pulled connector off the CAPACITOR with pliers, installed new DIODE ASSY.

After installation of DIODE and the control Panel, I plugged in the AC power and allowed the CAPACITOR to charge - this takes about an hour or so, then test. Works perfect!

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.

The spacesaver is mounted over the stovetop. I removed the oven, then removed all the screws from the cover. Removed the cover and located the TCO and removed the wiring and the TCO. Ordered the part VIA internet and replaced it . It helps a little that I was Radar tec. and taught Electronics for 10 years and repaired lots of Microwaves. However anyone could do it just watch what you remove and replace in reverse order.

This is the second time replacing this fuse, last time was exactly one year ago. The first time I replaced it, I removed the oven from the wall & disassembled a number of things to reach the culprit. This time I left the oven mounted & was able to access the 2 grille mounting screws on the top of the grille & remove it. Next comes the black plastic air deflector held by two screws & is mounted in front & on the right, it is shown on the parts list just above part #1434. After removing it, remove the two silver cover screws in the front, this cover also doesn't have a part # but is shown to the right of part #1410. At this point you can lift this cover enough to access the fuse which is on the left & held in place by one tiny screw through the clamp at the top, (careful not to drop it when removing). PS: Don't forget to cut the power to the microwave before starting!

This was the second time I've had to open up the microwave. 1st time display would blank out but system would continue to operate. Found solder connections on board to LED display were defective. Resoldered and unit was fine. This time I found the connection to the oven cavity temp cut-off was bad, plastic connection cover melted. When unit operated bottom lead and wire would heat up. Couldn't measure a Discernable distance so either wire or connector connection surface was not sufficient to carry the current. 1st replaced sensor still wire heated up. Replaced connector and there was no sign how heat from resistances.

One small Phillips screwdriver and one fuse puller (I used cord). Unplug unit. Remove the two screws on the vent face plate. Remove the one screw on the panel assembly. Gently let hang. Pull the fuse located on the upper left wall. Replace fuse. Reassemble.
