SOURCE: NO more Heating

The magnetron unit in the microwave needs to be replaced. To verify this you can ohm the wire connectors and the body of the magnetron. If there is no resistance on the ohm meter it is still good, but if you get resistance on the ohm meter the magnetron is shorting.

SOURCE: Whirlpool OTR microwave no oven 'fan'

FIRST ,,MICROWAVE OVENS ARE REALLY SAFTY MINDED AND THATS A GOOD THING....THERE ARE USUALLY THREE DOOR SWITHCES NEXT THE KEYBOARD--THE ONE ON TOP AND THE ONE ON BOTTOM ARE PRIMARY AND SECONDARY SWITCHES,,YOUR PROBLEM SOUNDS LIKE ONE OF THESE IS NOT MAKING CONNECTION..YOU MIGHT BE ABLE TO PRESS 'DOWN" WITH A LITTLE PRESSURE ON THE DOOR AFTER CLOSING TO SEE IF THE FAN WILL START,,,IF YOU NOTICE --THERE ARE 2 LATCHES(HOOKS) COMING OUT OF THE DOOR,,WHEN THE DOOR IS CLOSED,THOSE LATCHES ARE SPRING LOADED AND MAKE CONTACT ON THOSE SAFTY SWITCHES....THIS IS NOT A CUSTOMER REPAIR--MICRO'S ARE JUST TO DANGEROUS WHEN YOU TAKE THE COVER OFF--IF THIS DOES BRING THE FAN BACK ON--YOU GOT A BAD DOOR SWITCH AND SHOULD BE A REASONABLE REPAIR
THE OTHER SOLUTION STILL WOULD BE A CONNECTION PROBLEM ON THE KEYBOARD ITSELF-THE WIRES JUST PLUG ON THE CIRCUIT BOARD BEHIND THE KEYBOARD---STILL A EASY REPAIR--GOOD LUCK TUNICA

SOURCE: Sharp R-530ES microwave oven stopped working

You have a bad secondary interlock (lower door switch) or its mount is damaged or out of alignment.

We have the service manual for this model and have uploaded it to our site here to help you.

You will need the
free Acrobat Reader to view or print it in case you don't have it.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you only need a switch, you can order a universal type here for $5 postpaid.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: Microwave seems to be operating but does not heat food. Popping sound was heard just prior to this problem. Popping sound no longer heard but still does not heat food.

Replacing the Magnetron will fix this heating issue you are having with this microwave. The Magnetron is the device that is responsible for the heating action.

SOURCE: First of all, my do

BECAREFUL high voltage transformer inside of unit. Check for blown fuses on the control panel. Check the door interlock sitches. there are usually 2-3. A bad interlock will keep power from the magnatron. Check the thermal fuse, small dime sized disc with 2 wires. look for the schematic it will give the location usually near the magnatron. Checking the magnatron is a little more difficult.

Hello,

I regularly repair Amana commercial microwave ovens.

  • What is the FCC ID number from the tag?

  • What is the Manufacturing number (like P76695, etc.)?

  • Is it making any unusual noises?

  • Is it running quieter or louder than usual?

My microwave displays time etc, but does not turn on


That model number from the tag on your oven should be KCMS1555SS0, KCMS1555SS1, or KCMS1555SS2.

We would need more detailed information about what it's doing or not doing.

Does it respond to key presses?
Does the inside light come on when you open the door?
Can you enter the cooking time?
What happens when you press "Start"?
Does it run but not heat?
Does it count down but the inside light and fan do not come on?

Please post a new help request with the model number and detailed sympotms.

No power to GE Spacemaker Microwave


I have model GE Microwave serial # JVM2070SK02. I start to cook something and it shuts off 5~10 seconds. Keyboard is still lit up, but no clock, fan, light and you cannot operate anything on the key pad. Unplug the unit and it resets. Sometimes it cooks, sometimes it doesn't? It is getting more frequent with the shutting down problem?

GE Profile Spacemaker keeps asking for time date reset and will not operate


The power to the unit is drooping (when the heavy microwave load kicks in) causing the reset.
Try plugging it into a different outlet (whole different circuit if possible) and if that works then you have a wiring problem to the original outlet.
