Water. Water is a good conductor of heat. The boiler heats the water, a pump circulates it around the system and through the radiators where it loses heat. Cooler water returns to the boiler for re-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.

There are three things to consider, the magnetron "heats food" high voltage diode "sometimes cracks" and the high voltage capacitor "sometimes shorts" one or more can cause the symptom of no heat. I recommend a professional to assess.

Hi,
Check your heating element..

Asker's Testimonial " explanation very clear. will give it a go and see how simple it was. thanks Ronnie " - ronnieshomes

You can use to set the timing in order of the heat required. Also using the grade rating of the heating coupled with the time set, the food can be easily heated without burning.
To start with use low heat and long time, the try with medium heat and lesser time and then choose high heat and short time. You must be able to use the settings accordingg to your requirement.
Hope this advice helps

Hi


The water is not heating as the heating element has gone bad or a fuse has blown which is preventing heating element to turn on. To check the heating element you'll need to turn off the dishwasher, unplug it. After unplugging it check the heating element formineral deposit on it, clean the deposits using a soft brush and a cleaning solution(Don't scrub the elemnt hard). If this doesn't resolves the issue then remove the panel and examine all the wirin connections to the heating element. Now, use a multimeter and check for the resistance reading(ohms, Rx1) for the heating element. The multimeter should display between 1200-1600 ohms or 1.2K ohms. If it is less than 1200 then you'll need to get the heating element replaced. Also, check for any blown fuse around the element. This should resolve your issue.

Thanks

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?

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part
