    Yes it is not heating. The turn table does turn and the light turns on when I hit start. There are no unusual noises and it is quieter than usual since it isn't heating. The model number is NN-S559BA

    Thanks

    Your long subject line got cut off. Are you saying it's not heating?

    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises?

    Is it louder or quieter than usual?

    Do you have the model number?

It's likely that you have a bad high voltage transformer or magnetron.

So parts alone would be $65-75 plus shipping if you do the work yourself.

If you have to take it to a shop, that price will basically double.

This is only a 700-850 watt oven.

Most new ones are about 1000-1200W and would cost a less (maybe a lot less) than this repair.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Oven turns itself on


THE DOOR HAS A SAFETY SWITCH THAT SHUTS THE UNIT OFF WHEN THE DOOR IS OPENED KEEPING YOU FROM GETTING "ZAPPED WITH RADIATION" ACTUALLY ITS JUST RADIO WAVES, ANYWAY THE JIGGLING OF THE HANDLE TO START IT IS WHATS HAPPENING THERE. IT COMING ON IS JUST A SHORT IN THE SWITCH THAT MAY BE FROM AN ALREADY SET TIME, OR ITS JUST MAKING CONTACT WHERE ITS NOT SUPPOSED TO. ANYWAY YOU NEED A NEW DOOR SWITCH.

Hello, does the control panel light up? If it doesn't then probably the fuse has shorted. Now, if the front control panel does light up. There a number of thing going on. Door closer switch is working.

You can modify a standard, typical micro switch available at many places or, you can get an exact replacement from GE parts placed or you can try www.repairclinic.com or you can try a FixYa.com advertiser.

You are correct in trying the safety interlock switches ... they cannot stand the opening and closing of the door while the machine is running. To improve the live cycle of these tiny switches is NEVER open the door while the oven is operating.

Thanks for your question @ FixYa.com

The motor will not work. The interior light comes on, but the turntable does not go around. The cook time counts down, but no cooking occurs.


the turn table motor could have failed, but the counting down will be the monitor switch or a micro switch located behind control panel

Sunbeam SMW5500 micro/convection oven shorted out when opening door


You are decribing a typical Door Safety Switch problem. The Door Safety Switches has Failed.The Door Safety Switch is designed to shut down the Micro in the event the Micro is still cooking when the door is being opened. The first "Click" of the switch cuts off the "Cook". If it does not cut off the "Cook", the second "Click" blows the power. Otherwise it would "Cook" with the door open, and I need not to tell you how DANGEROUS that could be. It first Tripped the Circuit Breaker which supplies power to the Microwave. After Re-Setting the Breaker the same thing happened except this time the Micro is DEAD- not even a light working. Yes, there is a line FUSE inside the Micro. You however need to address the Door Switch SHORT before replacing the fuse. If not, it will just Blow The Fuse Again, and Again, until the Short is corrected.
Call around, ask How much to replace a Door Safety Switch.
Good Luck!

Shuts Off after 22 seconds


Time to buy a new microwave as it sounds as if the control panel is defective. A new control panel for this micro will run about 95 to 120 bucks + labor depending on where you buy it. I happen to like slightly burnt popcorn as well!! Nothing wrong with thats, as they say great minds think alike.
