JS998SK4SS General Electric Microwave Oven Combo - Instructions

Replaced High Voltage Diode. Very carfully due to the extream danger of a electrical shock.

The existing terminal block on my Ge oven/Range had melted due to a loose wire causing sparking and starting the plastic casing of the terminal block on fire and melting it, Part select made the part easy to find and had it at my house in 2 days. All I had to do was remove six screws to take the back sheet metal cover off of the oven. Unscrew the terminal connections remove two mounting screws that held the terminal on to the oven body. This was a little trickier than it should have been because the melted plastic had reformed making it very hard to access the mounting screws. i then mounted the new piece and plugged the oven in, it took 15 minutes and was very easy. definitely saved me at-least a $100 for the service call i would have made if finding the part wasn't so convenient

The repair went very easy. The replacement part was designed differently than the original part. It installed on the rear of the drawer with a screw as the original snapped into the side. This was a bit confusing when researching and looking up the part online.

The burner would work but you could not regulate the heat. I ordered and replaced the control switch for that burner. The part was like for like and reasonably priced compared to other websites and dealer. The picture showed that it was identical. I ordered one day and it was here the next. I had drawn a diagram of where the wires went on the old switch so it was very easy to replace. Probably took me 15 minutes or so. Works perfectly and by buying from this website it saved me a few bucks.

The draw pictorial was not very clear. I orderd the two rear supports for the over storage draw, not sure they were correct.
They were correct and the design had been upgraded to add strength to the support.
The draw is now operational..better then ever.

The hardest part was getting the correct part. I trusted the on line number and the first part I received was incorrect. I should have taken the part number off the old switch. When I did, I found out that the part number changed when I tried to order it. When the part came, the wiring instructions were not even close. I just took one wire at a time off the old switch and put it on the same terminal of the new switch. The repair was/is very simple made complex and too much time because of a wrong part and incorrect wiring instructions. As far as getting the incorrect and correct parts through the mail it was very fast. Received both parts in less than 3 days. A bonus is that I sent the old switch back for a rebate. Thanks for that.

It wasn’t the magnetron.
It wasn’t the diode.
It wasn’t just the fuse.
It was the High Voltage Capacitor (HVC). You know, the very thing they warn you about when opening the microwave. Just remember to discharge it using needle-nose pliers before probing around to find the problem. I also suggest you invest in a multimeter so as not to waste hundreds of dollars like I did; that way you can go straight to the real problem instead of replacing symptoms. If you replace the HVC, you will also want to replace the two fuses right in front of it. Also, there is a wiring diagram and a troubleshooting flowchart tucked behind the front console near the top. It is extremely useful!

Pull the old one put in the new one ... took about 20 minutes

must of had loose connection from wire terminal
to thermostat from factory. thermostat and wires
were melted. removed thermostat. and cut burnt
wires back. replaced thermostat and terminals.
used better quality terminals than factory.
also checked and tightened other loose connections. there was enough wire left after cut back to just put on new terminals.

Looked up the part, ordered it, and it was there in 3 days. It was slightly different than the old control, but a very well-written set of instuctions detailed which wires to move to which terminal. The entire repair took about 30 minutes, including moving the range out, replacing the control, and push the range back in place. Works perfectly.

Tried GE onoine parts department first and ordered the wrong part, then tried the customer hotline and they referred me to the right part but didn't explain that the design had been modified (the drawings had not been updated). I found an explanation on Part Select AND the parts were cheaper. Part Select sent the part, the necessary screw, and an appropriate instruction manual. Each support took less than a minute to screw in with a socket wrench.

Removed panel to gain access, removed wires from switch from burner that was not operating and attached them to switch for burner that was working. Burner worked, problem identified. Replaced bad switch with new switch. Problem solved.

Removed range from cabinets then approximately 6 sheet metal screws from the front of the range and two 1/4" sheet metal screws from the side to remove the front and top of the range. Lifted the cook top removed the two screws from the rotary switch and followed the directions included with switch to connect the wires. In reverse order reassembeled the range.
Quick & Easy

Pull range out of the "hole", and spin so that back of range is accessible. Remove cover over top "control area" on back of range. (Four screws that happen to be the same size as the magnetic socket that holds the interchangeable tip on a cordless screw gun. Simply remove this tip, and use the tip holder as a magnetic nut driver!). Remove the knob by pulling gently straight off. Remove black plastic retaining nut under where knob was. Inside are two small screws that hold the switch in place. Remove these screws with a magnetic screwdriver (If you drop these screws and lose them, you'll have a hard time finding them. Very small!!). Carefully follow enclosed instructions to move the wires from the old switch to the new switch. Put back together in reverse order.

Disconnected breaker. Removed knobs, plastic retaining nuts mounted to each switch shaft. Removed four 1/4 inch hex head screws on front panel and two screws securing defective switch. Removed bad switch, and replaced with new part. Took photo of wiring before removing old part. Referred to photo to ensure correct wiring of new part. Reassembled front panel in reverse order of disassembly. Turned breaker to on, and tested new switch. All worked well.
