GE model jes1358wk02 no heat


see this causes and fix it. God bless you
OK, get ready, this micrwave oven repair can take some time. This is where you must be able to read a wiring diagram and do some "live" checks on parts. First easy check is to make sure power is coming off your control board at the MW relay. Make sure of the wires and test here, if you have 120 volts at this point, you have ruled out a lot of parts that could be the problem. You have now ruled out any switch problems, control board problems, or a thermostat or 2.
If you do not have power from that MW relay on the control board, you must trace the wiring back to see if the proper voltage is going through your switches, any thermostats, and arriving at your control board. Your wiring diagram on your sheet will show you where and what to test. Below is a general switch test troubleshooting guide.

mwswitchtest.jpg mwswitchtest2.jpg If the proper voltage is coming into your control board and you are not getting voltage at the MW relay, then you need to replace the control board. If voltage is interupted by a thermostat or switch from your testing to the control board, then replace that part.Now, testing from the MW relay on to your transformer, high voltage capacitor, magnetron, and diode. Do not do any voltage reading from the secondary side of the transformer on, this can be a deadly microwave oven repair if you do not follow directions. This can result in electrocution and the "blowing-up" of your voltmeter, only do OHM testing with the power off and the capacitor discharged. Someplace in this circuit, usually before the transformer, you will have another thermostat to test. It is usually mounted on the magnetron. Do a quick OHM test to see if it is open or closed.
Now to test either the transformer, high voltage capicitor, magnetron, and diode, you must test each part separately. A good rule of thumb, if your capacitor is bad, change the diode also. Another note, if you are working on an OTR model and you have determined to be one of these "heating" circuit parts, you can not test these parts until you take the unit down. If you don't have the parts with you and you have to order them, order the magnetron, capacitor and diode and you will have a 90% chance of solving the problem. If it is an older microwave, order the thermostat also, most times you can return un-used, un-opened parts. Check with your parts supplier. This way you only have to take the unit down once.
To test these parts, scroll down this page and you will see a chart with component tests. Follow the instructions to find which part(s) are defective in your microwave oven repair.

I have a GE Profile Microwave Oven model JVM179SK01. The dial button does not work. It is not stripped as someone suggested before. You turn the dial and nothing happens, you push it in to make a selection...


Are you certain there is power to the unit?

You could have a bad latch switch or other component (fuse, other switch, etc.). To determine which it is will require having a volt-ohm meter and knowing how to use it, and the wiring diagram for the appliance, which can usually be found inside the unit somewhere.

Let me know if you want to tackle this, and I will help you as best I can. I do not have a wiring diagram to look at, but will help you to read it.

Works for approx 30 secs then it cuts off with a error Code F7 message.


Assuming yours is a model KHMS2050SSS0, here is what the technical sheet says about the F7 error code:

1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem.
3. Unplug microwave oven or disconnect power.
4. Check cooling fan operation
5. Check the magnetron.
6. Check P65 connection on the relay control board.
7. Check the P56/P66 connection between relay board and relay control board.
8. Check wiring to the 1200W inverter and control system. See “Checking Inverters.”
9. Check operation of all interlock switches.
10. Replace all parts and panels before operating.
11. Plug in microwave oven or reconnect power.
12. Check voltage at 4903-1 on relay board. If it is 120, unplug microwave oven or disconnect power.
13. Replace inverter.
14. Replace all parts and panels before operating.
15. Plug in microwave oven or reconnect power.
16. If problem persists, unplug microwave oven or disconnect power.
17. Replace relay control board.
18. Replace all parts and panels before operating.
19. Plug in microwave oven or reconnect power.
20. If problem persists, unplug microwave oven or disconnect power.
21. Check for reversed plug connection on controls or loose wiring.
22. Replace all parts and panels before operating.
23. Plug in microwave oven or reconnect power.

(This troubleshooting guide presumes one does not know how to test electronic components. That's why they say to replace and part and check it again.)

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If yours is a different model number, please reply back.

Microwave not cooking


I would say you have a bad door switch or door switch mount, or your door is loose or out of alignment.

But since it's new, and under warranty, I would contact Goldstar (LG) customer service to have them repair it free.

Contact LG at 1-800-243-0000 or http://us.lgservice.com

We're happy to help and we appreciate your thoughtful rating of our answer.

Wiring diagram Problem - Maytag MMV5207A 1100 Watts Microwave Oven


This doesn't have the diagram hidden away somewhere inside? Check at the bottom edge of the control panel, transformer brack, or rear of the oven. Otherwise, you can find wiring diagrams of earlier models that may be close enough. Just enter your model number here: http://tinyurl.com/gv383
