Toss out the magnetron and replace with a new one, but make sure to discharge the capacitor before tinkering around inside or it will shock the hell out of you.

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.

Tip

Error Code "d" - Microwave does not heat


The microwave could be in "Demo Mode" - Check your owners manual.

In Whirlpool/Kenmore models this is indicated by a lower case "d" on the right side of the display panel.

Most/All function except the magnatron (heat) work in demo mode so you can can learn to use the oven without actually cooking food

To clear "demo mode" press the "kitchen timer" pad and hold for 5 seconds until the "d" clears from the display... you may hear 2 beeps.

If the microwave operates normally, but does not heath at all, then it can be the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, your model number did not return any result, contact the seller here to purchase parts. (here in UK).

GE microwave model JVM1750DM does everything except heat food. Worked this morning fine.


Chances are the magnetron has failed, "heats food" the other possibility is the high voltage capacitor and diode. Repairs will approach the cost of a new microwave oven.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

I did more research along with the suggestion of an apprentice to have person to fix the microwave. I was unable to fix it myself. The microwave needs a magnetron .

Everything works except heat


Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron

MICROWAVE NOT HEATING


I have the same problem. Everything seems to work except it doesn't heat up food.
I remember last time when it was working. I pressed the start botton before I closed the door. So it didn't start automatically, and I pushed start and it worked(it still heat up the food), but it doesn't work now. Help Please!!!
I have a Whirlpool Gold GH5184XPQ.

Thanks in advance
