PSB2200NBB - Instructions

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.

the main issue I had is the appliance manual stating that the bulb should be "unscrewed". when I first read the manual, before I received the bulb on delivery, I tried "unscrewing" the bulb, which actually is a PLUG IN bulb. small wonder that it didn't come out! luckily I didn't break the connections off in the socket!

the online instructions were ideal - just unscrewed the right-hand screw (the only screw) and replaced the bulb by inserting gently but firmly)...getting the old bulb out was a pain, b/c it shattered in my grasp (with little bits of glass all over the stove!), but that has nothing to do with the purchase and installation from this site - all a very good experience

Watched a couple of repair videos on Youtube by searching for the model number. Found out what to do in order not to get shocked by the powerful capacitor.
Ordered the two switches (To be sure, I could have ordered a third switch as suggested in the videos.)
Bought a tamper-proof star bit to get the cover off. Followed the directions to replace the switches. - I broke the harness and had to use some super glue, but it's all good. I should have removed the harness instead of trying to get a switch out while it was still in place.
It's all back together, and the wife is happy!!

1) Removed 4 screws securing the microwave to the cabinet.2) Slid microwave out, unplugged and placed on a work surface that allowed lower trim to hang over. 3a) Removed two screws and removed the cover on top of the oven. 3b) Unplugged high voltage plug from Magnatron. 4) Removed wires from overtemp fuse mounted to Magnatron. 5) Removed the four screws securing the Magnatron to the oven. 6) Removed Manatron. It's a tight fit, but can be done without removing anything else. 7) Replaced Magnatron. This is where I needed the magnetic part retrieval tool. The nature of a Magnatron is the use of strong magnets surrounding the tube. Getting the four screws back into place wasn't possible with just a normal magnetic screwdriver tip. I used the retrieval tool to position the screws back in place. Be sure to not initially tighten any screw completely, until they can be evenly tightened. This ensures correct compression/seating of the shielding material near the neck of the tube. 8) Reverse removal steps. Plugged in and tested microwave function on a cup of tap water. 9) Reinstated in cabinet and got a big thank you kiss from the wife!

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

removed light cover and replaced defective bulb

Removed one screw, removed cover, and replaced lamp. Pretty straightforward.

Symptom: Terrible sparking coming from the right side of the microwave even with nothing in the microwave. The part that was behind the cover was the business end of what I learned was the magnetron,

Repair process: Without appliance repair experience I went onto Google and searched for parts for my model PEB1590DM2WW. I was able to find a great parts schematic on partselect.com. At first I ordered a magnetron and while waiting for the parts to arrive I also learned that the capacitor can also fail easily as described in the other install feedback on the partsselect website. So I ordered a capacitor just in case. These convection microwaves are around $600 new so a $80 in parts is not out of line for 8 years of service.
I installed the magnetron first and turned it on. sparking immediately continued so I quickly shut the unit off. After replacing the capacitor and letting it charge for several minutes before trying to start the microwave cycle was the issue. I choose to leave the replaced magnetron as the original unit was discolored and felt the replacement was inexpensive insurance. I also learned that if the wave guide (which is a plastic/metallic composite material) that covers the opening to the magnetron is burnt or has metal melted to it as mine did it will act similar to the microwave having metal inside the enclosure and will continue to spark and basically melt the wave guide further. Replacing the wave guide was very easy as well.

I am very thankful for the knowledge base and support available from Partselect.com as they made this repair possible on my own. Thank you partselect.com

unplugged power cable / unhooked front vent / unscrew the monitor panel / slide up to dislodge / take the fuse out and put in the new one in / fuse is located right in front of monitor panel once its open might be covered by wirings / you can unpin the cables from the panel to make it easier for you just make sure to put it back properly or you can have somebody hold the panel for you. Installing the fuse is easy waiting for the parts is crazy......

Easy to repair. One screw, remove bulbs, replace with new ones, secure screw.
