PK7800SK4SS General Electric Microwave Oven Combo - Instructions

Had to remove outer cover (special screws involved). Found the correct part at PartSelect.Com and it arrived 3 days later as promissed.

This oven has diffcult electrical connections at switch to get disconnected. I found it easier with the sw loose and in hand so that the connectors can be released with a small screwdriver.

One has to this in order to test the part wirh an ohm meter. I found the sw did not close but remained open and thus caused the oven not to function.

Removing interconnect switch is tricky but not difficult.

Outer cover replacement is not as easy as it should be, especially the sides.

All is well and working.

Microwaves are simple devices if you are know how to read and understand schemetic diagrams.

Turn off the circuit breaker to the microwave. Remove the 4 black wood screws that secure the microwave to the cabinet. Pull the microwave all the way out and set it on something that leaves you access to the middle access panel on the bottom. Remove the access panel on the bottom that has one screw. Unhook the 2 cables to the motor remembering which color goes where. Remove the 2 screws for the motor and replace the motor. Finish up in reverse...

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.

After opening the Oven door, I removed the glass cover to view and locate the bulb, at the inside, top front of the Oven. Removed the burnt out bulb by pulling it in a forward motion towards the front of the Oven, slid the new bulb into place and the Oven is again functional.

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......

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!

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.

I used a Trox bit to remove one screw, replaced the oven sensor and reinstalled the screw. The whole project took less than 5 minutes.

First remove all screws holding on outer metal casing of microwave. Next remove the back and bottom metal pieces. You will then be able to pull aside the outer casing so you can access the door switches. Check each switch with an ohm meter in both the open position and with the switch closed. If the ohm meter reads the same in both the open and closed position, the switch is bad. Check the top switch first. Replace switch and reassemble. Cheap fix for a costly microwave. Great customer service at Parts Select!

I looked at the exploded pic on your web site to find the location of the sensor. Next I removed the cover by unscrewing 15 screws then swaped the sensor and re assembled! Works great! Fixing it my self I saved at least 150$ and did not have to wait all day for a repair man who probaly would not have the part on the first visit.

Changed Fan Blower only, which cleared the Error Code F96.
Other parts have been kept as spares.

Turn power off to oven, removed screws holding oven into cabinet, get assistance to remove oven, I used 2 dinner table chairs to set the oven on, be careful as the front of the oven is heavier than the back. Removed the back sheet metal covers, about 20 screws or so. Removed Fan motor, replaced with new fan motor, and reversed installed. Oven works great.

TERRIBLE!!!!!!!
FIrst part arrived broken
Second part arrived broken
Third part arrived broken
Finally on the 4th try, the part arrived and was not broken.
I will NEVER again order parts from this company.

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
