Microwave oven not heating thoroughly

Magnetrons in microwave ovens do not last forever, and are subject to failure from power surges. When the microwave oven no longer heats food, it is likely that the magnetron has failed.

The microwave may not be cooking at full power, check the settings. If okay the magnetron is on it's way out and will eventually fail.

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

If the steam is not leaking out of the microwave it is no problem. Steam is normal when you heat moist items. If it is leaking out you need to replace the door seal, but steam will not start a fire.

I'm having the same problem with my microwave -- GE JVM1533WD 002.
The inside light, cooling fan and turntable are all working but it is no longer heating food when the Start button is hit.
The unit is noticeably louder than normal, too.
Any suggestions? Thanks in advance for your help.

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Microwave popcorn gets VERY hot while cooking. Even though the turntable is made of temepred glass, intense heat applied in the same spot over and over can weaken the molecular structure of the glass. After so many expansions and contractions, it will crack because fatigue will cause some molecules to expand less than others, creating stress. This is yet another reason I recommend to my customers that they place the food off-center on the tray - not in the center. The oven also heats better when the food is off-center because the food is more thoroughly exposed to the microwave energy. Until you get a new tray, the photo below can help you.
