Question about GE JES1290 Convection/Microwave Oven

Jes1290 microwave runs but no part of the cooking section works (microwave, heating elements). Replaced smartboard per flowchart, all three door switches appear to function properly (ohmed out). When door is open turntable turns (should not). Any ideas would be helpful.

    Switches appear to be ok, test fine and appear to be mounted properly with no play. Disconnecting the middle switch which I believe is the monitor switch does turn off the turntable, light and fan however nothing works. how do I test the monitor circuit?

    Thanks,
    Kenny

Hi, if it keeps running when the door is open, that's usually due to a bad door switch or broken / loose door switch mount. You just need to fix the door switch or door switch mount to solve the problem....

Convection oven doesn't heat


Possible that the relay is faulty or there is fault on the control panel. It can also be related to problems on the thermocouple or sensors which can cut off prematurely the element.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

Microwave seems to run, but won't heat.


We have a similar problem! It sounds like a problem with the microswitch inside the unit that the door is suppose to engage when closed. If not engaged properly, it will not cook. We had the switch replaced last March but it has started acting up again. We can press in on the door and/or lift it slightly and it will cook. Try putting time on the counter and hit start. It the word "cook" appears then try moving the door slightly and see if the turntable starts turning. If not, then you may have a more serious problem. Good luck!

It makes noise like it's working but isn't


When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.

Microwave runs but does not heat food either with sensor or manual timing. Occasionall will displasy 'SENSOR ERROR'. Have closed door and pressed CLEAR/OFF per manual instructions, but still does not...


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Then let us know if the hard reset does not fix it.

INFO: On GE models, "SENSOR ERROR" appears on the display when:
  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the maximum amount of time. Use Time Cook to heat for more time.
If the reset didn't fix it:

When you hit Start to cook, do the inside light and turntable come on?

Any unusual noises?

Is it louder or quieter than usual?

Do you have the model number?

These answers will help me judge whether it's in the high voltage section (magnetron, transformer, or diode) or the control section (door switch or control board relay or connection).

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

JVM2050 Doesn't cook food sometimes


Not the magnetron if intermittent. Probably a bad smartboard. Easy to replace if you know the basic precautions to take.

Lights up BUT does not cook


was there any motor that should run as you turn it on, the fan inside and the rotating table motor. try to replace that micro switch at the door that bubbled out and burnt. try to test or replaced right away the industrial diode that is connected from the capacitor to the ground of the microwave.

First, order by number. Some illustrations are general. Second, you may find a board rebuilder who will fix yours or exchange it.

I've done this and found that the correct product was sent and worked well.

Microwave will not heat


If all controls on the panel work fine but the microwave does not heat, then either you have a defective door switch,the smartboard is defective, or you have a defective magnatron.Most likely one of those three.
