PK7800EK7ES General Electric Wall Oven - Instructions

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.

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.

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.

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.

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.

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.

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

I ordered the glass assembly which promptly arrived and I proceeded to unscrew the broken glass assembly and (by myself) removed it with ease. I then placed the new glass assembly and replaced the screws. It was really an easy job, I just retraced my steps from removing the broken assembly and replacing it with the new assembly. By the way, it was the first time I had done this.

It is easy to repair the burnt out bulb if one has the correct bulb. Your website is very user friendly and your service is great. I was not able to replace the bulb at this time because our RV is at the repair shop for some other matters. I am sure the installation of the new bulb will go smoothly. Thanks for asking.

there was one screw holding it on the back wall of the oven. It was easy enough that my daughter installed it with my guidance.

Very straight forward repair except for removal of the fan mount plate. There are 4 sheet metal screws, 2 of which are obvious and shown in the appliance diagrams, and 2 of which are neither on the appliance diagram nor obvious. These screws are beneath the motor assembly and oriented with the heads between the mounting plate and the top of the oven - about a 3/8 inch gap. Removal was accomplished using a 1/4 inch open end wrench strictly by feel as there is no sight line. Not all that challenging, but still a pain. On reassembly, these screws were reversed so that the head is now on the top of the plate and more accessible.

I removed the main cover ( torx security bit required) and tested the magnetron, capacitor, diode and door interlock switches according to instructions found on the internet. The capacitor and diode tested good but the magnetron looked burnt and corroded on the tip. The magnetron I received was an exact replacement for the original. It was easy to replace the magnetron which arrived in 2 days standard shipping. I also cleaned the fan while I had access to the inside area. Hoping to get another 18 years use from the microwave!

Step 1, turn off circuit breaker, verify no power at the back of oven

Step 2, remove oven from wall/housing by removing 4 mounting screws, 2 on each side, just on the inside after opening the oven door...this was the most difficult part doing the repair on my own as the oven is a bit heavy...I was fortunate to have a old Workmate 425 work bench that folds/collapses, this allowed me to slide the oven out and drop down about 2 inches...reinstalling the oven I did have to use 2x4s to shim the oven level to slide it back in, with someone to assist this would not be necessary.

Step 3, remove covers to gain access to the blower and sensor

Step 4, remove the sensor

Step 5, install new sensor

Step 6, turn on the circuit breaker

Step 7, test the oven (success, Y, turn off breaker and reassemble all covers, install the oven, secure with the 4 mounting screws, turn on circuit breaker, test one more to ensure of proper operation...N, go to step 8

Step 8, turn off circuit breaker, reinstall original sensor

Step 9, remove blower

Step 10, install new blower

Step 11, turn on circuit breaker

Step 12, test oven, problem resolved, Y, go to step 13, N, continue troubleshooting.

Step 13, turn off circuit breaker

Step 14, replace all covers and reinstall oven, secure with 4 mounting screws

Step 15, turn on circuit breaker

Step 16, test, still operating properly Y, receive hugs and kisses from wife, N, do not make eye contact with wife, take dog for a long walk.
