Its sounds like the magnetron. If it was a voltage problem, or something else in the circuit, there would be no power to it as a safety feature. You could get it serviced, but depending on what they run in your area, you might just be better off getting a new one.

I put my Microwave on for 30 min and it suddenly stopped working, suggestions?

If there is no power at all to the display or the panel then it is failure of the board. But if there is power without heating, if the turntable/fan/light works, then it can be related to failure of relay, Magnetron, Waveguide or capacitor.

I have a Kenmore Microwave Oven.The turn table stopped rotating and the unit does not heat. It sounds like it is working but it does not heat. Does the turntable have something to do with this?

What you probably hear is the fan. If it's not heating the problem is almost certainly the magnetron. The magnetron is the main component in every microwave and can be very expensive tp replace. You'll be better off buying a new microwave. The prices on new ones have dropped dramatically, I saw a 700 watt unit selling for $50.00.

KitchenAid KCMS1555RSS stopped heating. Everthing else works, full display works, time counts down, turntable rotates, light comes on, etc. but no heat. makes loud hum. Magnatron? Cost to replace? Unit is...

If it is making a loud noise, check the diode and magnetron for damage.
The fault may be just the diode and a reasonable cost will be involved. If it is the magnetron, depending upon where you purchase one from will command the price.
Hope that helps.

My KitchenAid microwave oven's model number is KCMS185JSS-4. Manufacture date is July 2005. It's been working fine until today, with an occasional glitch in the digital readout... sometimes the letters...

Either your high voltage rectifier or magnetron (or both) has failed.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)

Microwave turns on but doesn't heat. Turntable does not rotate

The magnetron (the part that heats the food) is probably done, they tend to go out if the fuse didn't blow and it usually isn't worth fixing as the cost of the magnetron is almost what it would cost to buy a new microwave.
Sorry for the bad news.

DCS - CMO24SS - 900 Watt - Microwave not Heating

If all appears to be running as its working but just no heat. Could be issue with magnetron. You could also have loose connections to magnetron or somewhere in high voltaged as well.

The microwave is not heating. Light comes on, fan comes on and turntable rotates but nothing gets hot.

either your hi-voltage diode,capacitor or magnetron are defective,if your not electrically savvy,don't open the unit up, by hi-voltage i mean the cap can store up to 2,000volts a.c.appx 18 times whats at your plug in receptacle,if you do tackle it,make sure to completely discharge the cap before attempting any repair...gooid luck and be safe

If we close the mircowave door the units start to run by itself. - it will not heat, but the light comes on and the turntable rotates it will not stop until we turn the power off - when power is turned...

i think you have a welded controller, either a digital one or a mechanical one. microwave won't run unless you switch it to run. the door switches are safety switches to turn off the microwave once you open the door. if you have a digital controller, you could have a welded relay, if you have a mechanical timer, it could be a welded contact at the timer. another thing is that it should heat what ever you are heating. if it is not heating, check if it has a fuse and if it is busted. some fuse are installed to protect only the magnetron that is why the light and turn table are still running. if there is no fuse to the magnetron, then check the diode from the capacitor to the ground. it could be open. if not then you can have a bad magnetron. i hope i was able to help.

If the oven is not heating food and the turntable is not rotating, it's a serious problem such a as a low voltage power supply, and up to replacing the magnetron (considering getting a gently used replacement oven on Craig's List or elsewhere).

If the oven has a turntable and is not rotating, that might be a separate (and easy-to-fix) problem by itself. I replaced mine, and it took 10 minutes.
If the turntable doesn't rotate, either the small ac motor has failed, or the coupling from the motor has come loose. Unplug the main power to the oven. Remove the 5 or 6 screws underneath the oven to remove the access panel to see the small ac motor. There will be an electrical plug with two wires connected to the small motor---unplug it. Take out the 2 screws that hold the motor in place, then inspect if anything seems to have come loose. If everything was mechanically o.k., then the motor is bad.
It's a fairly universal part number, a low voltage ac motor. Make sure that the voltage rating is the same when looking for a replacement. You could check on-line with a search-engine or Sears.

Good luck, hope this helps.
