Vent fan does not turn on at all


If your cooktop lights recently blew, or if the relay that controls the vent fan is affected, you may need circuit board repair.

Otherwise, it may be a bad fan motor.

There should be a technical sheet hidden behind the grille or behinds the controls. It's very handy to locate and test components.

You can find a video here that shows you how to remove the grille & controller in about 5 minutes.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

With the model number, we can offer more specific advice or an estimate.

But since FixYa does not notify us experts of follow-ups, you would need to post a new help request.

I have a JVM1190, & the display went blank, There is power @ the plug, is there a reset?


It may be a blown fuse or the thermal cutout (TCO) / thermostat on either the magnetron or on top of the oven cavity.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.


Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

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.

No display on microwave touchpad for ge Model JKP62G


The GE JKP62G Microwave / Oven combination has an internal fuse behind the control panel for the microwave. The oven will operate but the microwave will be totally dead (no light, no clock). Turn off the breaker for the oven at the fuse box (30 Amp double breaker). In order to replace the fuse you will have to open the door to the microwave, remove the two screws (Torx) from the front control panel (located on the left edge of the control panel), wiggle the panel to the left (there are two metal tabs that stick into the metal frame of the microwave on the right of the panel) and then tilt the panel down from the top. There is a metal bracket that holds the control panel to the microwave at the bottom (don't remove it). Look towards the top of the microwave inside the area behind the control panel and you will see a 15 Amp screw in fuse. Replace the fuse and that should fix your problem.

Intenal Fuses for Lights


In some cases, it may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

In some cases, a light failure where a bulb shorts can damage the control board itself.

If the problem is on the control panel, we regularly repair these for customers nationwide by mail for $39.95 postpaid in about a week.

Feel free to contact me
directly (and please remind me of your full model number) for more information & help.

GE Microwave


I repair GE circuit boards, but the problem is not your circuit board.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.

(Your model may use a different kit - this is shown for illustration purposes only).

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

Have a ge spacemaker xl1800 - f3 error


I had the same problem. I removed the grill and opened the control panel as I read an answer from "GENE" on APP (Appliance Pros) that this indicated a short in the circuit board (TouchPad). I was going to replace the faulty circuit board but when I opened the control panel there it was......One wire harness had just came unplugged!! I plugged it in, reassembled and the microwave works again!
