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

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.

Sounds like the Magnetron has stopped working. The Magnetron is is a specially designed powerful magnet that generates the high frequency microwave energy used to heat food.

Microwave does not heat


he failed heating device is called the Magnetron. if the entire microwave oven is inoperable and, it will not power up when plugged in, this will be a failed power board or fuse. Now, if the microwave works and the fan blows but, here is just no heating, this will confirm Magnetron failuer.

We have just purchased a GE microwave oven, model JES1358WL. the light is on, the turntable turning, the control panel shows cooking and seconds counting down when attempting to heat cup of water. it is...


First: never attempt heating pure water in a microwave, that is dangerous.

Ensure the oven is not set to the minimum power, otherwise the heating will be minimal.

Try heating some food at maximum power for two or three minutes, if it does not heat, take it back to the shop.
