Ge jvm1850sm2ss suddenly does not heat food any longer

SOURCE: Microwave won't heat food.

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

The problem you are having is that the magnetron that actually does the heating has gone bad. The fact that everthing works fine rules out any type of bad fuse since there is only one 15amp ceramic fuse in most cases in the unit itself. The magnetron is located behind the control panel on top and has some cooling fins on it. Replacing it if you are a do-it-yourselfer is pretty easy provided you can find one at local electronic supplier or on the internet such as www.mwoparts.com if you would like to see what it looks like. It is held in place with typically 4 screws. It has two to three terminals depending on make and model and age. With everything unplugged it comes off easily enough with no desoldering or soldering to do. There is a High Voltage Capacitor and Diode that could be bad also, but without being able to check it in person it would be difficult for me to tell that they are. In my experience the magnetron is the first thing I replace and have never replaced a capacitor or high voltage diode in the past 20 years. Good luck and God bless.

The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.

Please rate my response if it was helpful to you.
