how old is the machine, microwave ovens have a tendancy to do the ridiculous for no possible reason. a check of the main power fuse within the unit might help. it is a large fuse 10A> that supplies the transformers

You probably have a defective magnetron or blown fuse supply power to magnetron.

SOURCE: My spacemaker just stopped heating food. What do

This is a microwave, correct?

I suspect the door lock interface switch(es) are burned out. Unplug it, be mindful of the 25,000 volts in the silver thing. Check the micro switches (look where the door closes on the top right side, probably) two positions, normally open or normally closed. check them for proper operation.

Micro switches are the most common of microwave failures because most of us open the door while the machine is running causing arc at the switch and burning up the little contacts.

Sounds normal when running but will not heat food and turntable does not work


You didn't specify a particular model, but the no-turntable and no-power symptoms are likely linked. Many microwaves have sensors to the turntable motor to tell if something being heated has been run into a wall (round turntable in a rectangular box, it can happen), Depending on the model, it may reverse direction, or it may just stop turning. This is both to keep from mucking up any reduction gearwork likely at work to turn some small motor spinning at a higher speed into a big table with a few pounds of food turning slowly with reasonable torque. It also will stop so that things won't get tipped over - no good to anyone if a poorly chose top-heavy bowl full of scalding liquid gets tipped over, flooding the microwave and burning whoever opens the door.

So... I'd remove the carousel plate, if possible, and see if the base is all gummed up with old spilled, ultra-baked-on crust or gummy residue. if so, between washcloths with scalding water and some gentle cleaner, like Simple Green, try to clean up the area and remove what might be freezing the spin shaft up. See if you can wiggle the shaft or turn it slightly with fingers or a small pair of pliers. If not, there may be more stuff gummed up further down the shaft. Don't expect to just spin it, it's probably tied to a motor with a belt or gear assembly that will put the mechanical advantage working against you.

After that - you can try unplugging the oven for a few minutes, in case it's either overheated, or in a 'safe' mode, or look for an owners manual for your specific model to see if there's a button combo to reset things, (or accessible fuses).

Good Luck!

Nec microwave. Turn table working and fan working but the unt is not heating.


Magnetron is no longer function. The magnetron resonates at a specific frequency and outputs energy (microwave frequency) which hits your water atoms within your food and excites them (thus providing a friction = heat).
The magnetron and high voltage diode that accompanies the magnetron need to be replaced.

MY LG microwave oven model no MH6344W does not heat the food .The oven is fine after 1 minute microwaving if i remove the food it is as cold as it was. What would be the reason please explain. I tried...


Hi,

If the food is not being heated it means the magnetron is not working. The magnetron is the device which generates microwaves which heat the food. It could be the magnetron itself which is faulty or it could be one or 2 other components causing the magnetron not to work. You will have to take your microwave oven to a service center to determine the exact cause & get a repair quotation.

Let me know if you need further assistance.
Best wishes,
Graeme

Sharp microwave losing cooking power


If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

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
