JES1289SK01 General Electric Microwave - Instructions

Continuity checks showed the flame sensor was open. Schematic notes it opens at 217 degrees and closes at 30 degrees. Removed sensor and placed in freezer for twenty minutes. Tested sensor and it was now closed, reinstalled and microwave worked normally. Ordered new sensor in case the original is operating at too low a temperature.

I took the cover off and followed the electric current to see if it got as far as the display.
I did not get past the thermostat shut off where the current stoped. I jumped the thermostat and the unit worked. The part was so inexpensive that I decided to replace it rather than try and freeze the old one in hopes of "reseting" it.

Door microswith was stuck on. This is caused, I discovered, by frequently stopping the oven, while running, by opening the door rather than using the stop button. Causes the switch to arc and eventually fail. This causes the safety microswitch to trip the breaker when door is opened. There are little nubs sticking up on the spade connectors. You must squeeze them down before you can remove them from the switch. The main door switch is the upper one, mounted at an angle. You have to remove the latch assembly to remove the switch. The problem was obvious once I got the switch out. This problem could also blow the fuse, but in my case the breaker tripped first. Use an ohmmeter to check switch and fuse. The door switch is normally open. The safety switch is normally CLOSED. Instructions inside were helpful and described this problem. So, avoid this repair by always stopping oven with stop button!

removed cover and tested fuse, fuse ok, check flame switch (thermostat) bypassed it with thin wire ,all power on!!...ordered it, got it, replace it within 5 min, as soon as part arrived.

Traced out 120volts from neutral to hot though fuse, and "high limit" switch screweed to far side of oven exterior cavity. High limit thermostat was "open". Jumped it out to see if unit would produce heat. Melted 1/2 cup of ice in thirty seconds. Ordered new part. Later foud out hi limit can be "re-set" by subjecting it to sub-freezing temperatiures. This is true, but I installed new part just to be safe. Machine is working fine now and has been in daily srvice for over two weeks.

It pays to troubleshoot a broken appliance before thinking about buying a new one. I removed the cover and found the manufacturer's circuit and troubleshooting diagrams inside. The fuse was good, next in line was the flame sensor. Meter showed it was open, so I knew that was it. Disconnect the wires and screw, replace part, replace cover. DONE! I knew I had the right part from the pictures on PartSelect's web site. Total cost under $20 compared to ten times that for a new one. Had the part in two days.

Removed the three screws holding the cover on. then rmoved the two wires from the capacitor. Removed the screw holding the end of the zener diode to the chassis. Removed the diode from the capacitor. installed the new capacitor and replaced the blown fuse then reversed the removal process.

1. Remove trim kit - Philips head screw driver
2. Remove Microwave from the wall - Philips head screw driver
3. Remove outer microwave cover - required tamper proof torx bit drivers
4. Replace Magnetron thermostat. On this model there are 2. in this case it was on top of the unit tied into the wiring harness to the main panel.
5. Reinstall microwave and trim kit

Fast & easy. I was able to determine that this foot would work from the descriptions on online!! Thanks

they had everything I needed, friendly service, fast shipping, no problems

Remove the door and order the part. With in a day the part was at my front door. 30 minutes later was using applicance. Superb service from this company!!!!!!!!!

My husband burned the microwave by using alumifoil. It was working for a little while after that but next day, the microwave was completely off. He thought the thermostat was broken, ordered the part and replace it. It's fixed and working fine now. Someone mentioned that if you put the broken thermostat in the freezer, it will be reset and fixed. I tried that also. I wrap the thermostat and put it in the freezer for one day. Now it's working!! I didn't know about that before I ordered the part but it wasn't expensive at all. So now, we have extra thermostat!!

removed microwave cover with security star socket (4 star screws) wasn't sure if it was thermostat cavity or thermostat magnetron ordered both for about $25 with shipping fee replaced both and microwave working again

After opening the case (the most difficult part of the job), tested the fuse (good) next in line on the power lead was the "flame sensor". With my ohmmeter it read open. The schematic noted that it opens at 212 degrees and closes at 32. Put it in the freezer for 15-20 minutes while I ordered a replacement. Upon rechecking, it had reset. Reinstalled it and everything works fine. I did receive the new one and it's on the shelf, just in case.

I determined that one of the 4 micro switches that interface with the door was faulty. Ordered that part and replaced it. Had to remove the cover and front control panel (without removing any connections. Two philips screws hold the limit switch assembly to the bracket. After removing those screws, twist the whole switch assembly clockwise around the mounting frame and now you can remove the defective micro switch and replace it with a new one. This works for any of the 4 switches.
