I have a Frigidaire microwave oven.... as it was heating food it just died, minutes later the power was back on by itself. I reset the clock and date,all seemed fine till I tried heating-up food.
It does not heat-up. The microwave is 5 yrs. old but in great condition. Is it fixable? Could I do it myself?

Most of the time the magnetron is defective if the food is not heating up.
In some cases there is a defective low power transformer or other componenents associated with the magnetron.
I would suggest to check the owners manual under the warranty section. Sometimes the magnetron has 5 years warranty.
Good Luck.

How do I get the heat to work?


Hi Marc, there is no 'heat' per say with microwave ovens as one would find in a convection oven. Microwave ovens operate by generating electromagnetic fields (within the microwave band) that causes water molecules in the food item to vibrate/rotate creating friction/heat - within the food item as opposed to the surrounding space (this would be convection)

Difference between a convection oven and a conventional oven


<span>A convection oven is equipped with a fan to speed the circulation of heat around the food, thus cooking it faster and more evenly than conventional ovens. <br /><br />Conventional ovens rely on radiant heat that rises from the bottom up to the top of the oven. Convection ovens cook foods approximately 25% faster than conventional ovens, and the oven temperature can be reduced by 25&deg;F for most foods. <br /><br />No special cookware is required. Just like conventional ovens, convection ovens can be gas- or electrically-heated. As with any major appliance, it is always best to carefully read the manufacturer's guidelines and instructions for operating the oven.</span>

I have a sharp over the range convection microwave modelr-1874F The convection works but the microwave sounds like it working, the turntable turns but it does not heat the food we tried unplugging it for...


Every time the microwave part of an oven do not heat it normaly means a faulty MAGNETRON (the device that produces microwves) unfortunately if it's the magnetron they are allmost as expensive as the oven it self, you could allways check for a burned fuse, (allways be prudent opening an applyance)

Good luck!

Small amount of white smoke coming out of kenmore convection microwave in oven mode


That is usually caused by a build up of fat from microwave cooking on the heating element. It will clear under normal conditions and return if one cooks foods like bacon etc, un covered to prevent splashing of the food that is being cooked.
Hope that helps.

On microwave mode the oven makes light buzzing noise and does not heat food. Convection oven and grill functions work perfectly. michaelchrys@yahoo.com


The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse and the diodes), then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

My delonghi 800w microwave oven works but does not heat up food


If your handy with getting the cover off and looking inside... check the obvious.
I suspect :
fuse
thermister
relay
If both microwave and Heating elements dont work, then I will assume the magnetron is ok, ans we are dealing with a high voltage issue... and you will need at best... a volt meter and or neon troublelight...
moust appliances have a simple schematic inside... I would start with the heating element first... trace wiring back to circuit board... usually one side of the heating element is connected to the white wire (neutral) and live (Hot) side is controlled thru the circuit board... so finding the neutral should be easy... then trace with neon light or voltmeter...

I know easy for me to say... but with everything else working... it doesnt seem to be the microprocessor that controlls the unit...
