Mmv4205ba thought I was using the timer but I think I was using the regular microwave let it run for 40 mins now it doesn t heat but everything else works how do I fix it or am I better off replacing it?

SOURCE: GE microwave will not heat, everything else works, any ideas?

Hi! the problem you have stated indicates that the magnetron its not functioning, check for busted fuse.

SOURCE: Maytag Over-the-range microwave runs but does not

Please remove the cover and check the door safety interlock switches. Check with a contunity checker or a volt ohm meter.

What happens is thjis: when the oven is running ane you open the door, the tiny contacts in these little swirtches arc and burn. Eventually, the switches fail. When this happens, the oven doesn't know the door is closed. When The door is open, the oven will not turn on the magnatron. No magnatron, no heat.

It could be the start capacitor, but not likely compared to the switches. Dont try to service the capacitor unless and until you understand the danger.

My Kenmore 721.63259301 would not heat items up so I came here and saw the parts required and was just about to order them when I checked the online owners manual and found this. FULL FIVE-YEAR WARRANTY ON
THE MAGNETRON For five years from the date of purchase, if the
magnetron in this Kenmore microwave oven
fails due to a defect in material or workmanship,
Sears will repair it free of charge.
My microwave has a manufacture date of July 2009 so I will be taking it right to the closest Sears repair center for a free repair. I suggest everyone do the same.

You may just have a failed door switch.
