Not working My microwave is not working... it gets switches on n runs.. but teh stuff dosent get cooked.. not even heated up/.. What could be the proble..? it is an year old

This is normal. Kenmore microwaves will stay running with fan and light on for a short time after food is cooked. The reason is to air out the microwave after cooking. Things like pop corn, Bacon etc. have strong smells after cooking. The ventilation helps to remove odors.

bad diode or inverter board or magnetron itself---diode fails first and inverter is power board for magnetron which does the heating.

Microwaves contain high-voltage parts that can be deadly, even when unplugged, unless handled correctly. Unless you are a qualified expert, don't attempt to get into its inner workings.

First, use this water method to double-check if there is actually an issue with your microwave not heating:

1. Fill a glass measuring cup with water to the 1-cup mark.
2. Set the microwave to heat on full power for 1 minute.
3. Repeat the process with fresh water a handful of times.
4. If the water is not consistently warm, your problem is confirmed.

If your microwave is failing to heat correctly, you may be on a previously programmed setting. Press the STOP/CANCEL button and start the heating process again, but use a higher power setting. This may correct the problem.

If the microwave senses an open door, it will not run. Check to see if a defective or loose door-safety interlock switch is to blame. If tightening it doesn't work, a replacement may be necessary.

Did you know? Neglecting to hit the STOP/CANCEL button on the microwave before you open the door to remove your food damages the safety switch over time.

Microwaves installed above the range may be affected by steam from cooking. Condensation collecting on the circuitry can interrupt heating. Allow the circuitry to dry out by avoiding stovetop cooking for a few days. If you're still having the same problem, it could be a loose connection in the circuitry or a faulty door safety switch.

There may be an issue with the circuit board and its connections, and that work is best left to a qualified professional.

A buzzing or humming microwave that emits a faint burning smell could signal a damaged magnetron, high-voltage capacitor or diode. Replacement magnetrons are expensive, so if a service professional determines that's the problem, you may be better off buying a new microwave. Capacitor and diode parts cost much less, but remember, you'll be paying for the expertise to have them installed correctly and safely. It may still make more sense to buy a new microwave, especially if it's a simple countertop model.

The same thing happened to my microwave this morning while heating a cup of water, which broke into 3 pieces too before the water hadnt even hot.
Maybe you have already solved your problem and I just share my experience.
I am trying to call the manufacturer nearby and ask for the turntable, but I am afraid the new turntable dosent fit my a little bit old microwave.

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.
That said, you can get free estimates on the cost of a repair but you should also consider a replacement which may be a better option for you.

What they do not tell you about over the stove microwaves is that they are constantly deteriorating due to the steam, oil, and other cooking fumes from the stove below. As a result, their life expectancy is definitely diminished.

Hi,

As long as the oven's metal bottom is sound underneath the rust, there isn't a problem. The cooking chamber walls are so thick and highly conducting that they reflect the microwaves extremely well even when they have a little rust on them. However, if the metal is so rusted that it loses most of its conductivity in the rust sites, you'll get local heating across the rusty patches and eventually leakage of microwaves. If you're really concerned that there may be trouble, run the microwave oven empty for about 20 seconds and then (carefully!) touch the rusty spots. If they aren't hot, then the metal underneath is doing its job just fine.

Thanks.

bad micro switch in door handle, 79.95 for GE man to check,9.61 for the part and changed it myself

It is the fan. Im guessing it only happens on combination cook and not when you are only using the microwave setting. It happens because the oven is hot and it helps to cool it quicker. It is normal. The microwaves are not working and neither is the oven-just the fan.

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician, as repairing microwaves is a pretty risky job.

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.
