My microwave is not heating

When it did heat food before and you used the same settings now, the microwave must be defect.
But before you are sure, put a cup with water in the micro and try to heat that.
Dry food can't be heated in a microwave. There must be some moist in the food if you want to heat it in the microwave.

A model number would have helped, but I can give you a generic answer.
It may be a bad door switch or mount.
(Anybody in the home opening the door while it's cooking?)
See our help file on door switches here.

If your microwave runs, but doesn'theat your food, verify that you have selected a cooking setting. You mayaccidentally set the timer. Test the magnetron by placing 1 cup of water in themicrowave and heating the water for three minutes. If the water doesn't heat,your magnetron is dead.

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.

i found on my micro setting if i accidentally set it up for convection, it stays that way and therefore just heats slowly when I think i'm microwaving. i have to re set it after i use convection or it defaults to that and therefore will not heat / microwave.

in a microwave, there is no heating element. There are microwaves that heat up the water molecules, they make them spin fast and that's what heats things up. Running it with nothing in it, you really can tell if it's not working by that test either, again, nothing to heat up. I would put in a cup of water, set on high for 3 minutes and it should boil, if not, get a new one for the price, why mess around?

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.
