    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:

Why microwave fan turns on when I shut the door?


on most microwaves this is an indication that the door safety switch (closed) has malfunctioned some how , id suggest not trying to use it as you can become harmed if your inside this machine , if its a high end machine or part of a matching set of appliances then id have it repaired , otherwise im afraid unless you've got a relative in the business , its not going to be worth repairing as costs to repair will be greater than new one , that's my expiences with them anyways

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.

My Sharp microwave stop getting hot. How can I fix it.


It is likely something in the magnetron circuit has failed. This could be the fuse, capacitor, or magnetron itself.

Another possible is the safety interlock on the door latch.

First up do not go poking inside this circuit yourself unless you know certainly how to discharge the capacitor properly. It will hold a lethal voltage even when the oven is unplugged, for an unknown length of time.

That said, you may find the cost of repair by a tech is not economical anyway, with a minimum labour charge of say $100. You might be better off buying a new one, and having the warranty on it.

I had a power surge and it blew the fuse


Open it an check the thermal cutouts for an open circuit and for burned wires if you don't find any just replace the fuse. The usual cause is the magnetron and an aging capacitor. I save every microwave people throw out to get the magnetrons... i always seem to have the correct size, bolt pattern, fin pattern etc to repair a microwave fast. With the glut of brand new microwaves for $40 or so at Walmart or other places no-one seems to want my repaired microwaves but i love fixing them anyway.

I ran my micro oven for 60 mins. empty. what happens to oven.


When that happens, the magnetron overheats, which can damage or destroy it.

Only a new magnetron can fix this.

Have magic chef mcd990arb. it was zapped by power surge. what could have been damaged and it is worth repair


Well if it has been Zapped then usually it is only? the Power supply side of things, the Bridge Rectifier, Controller etc, especially if it wasn't actually "heating" at the time. But also it may have fried the Computer Chip, in the "Brain" of the microwave. These days though, it often costs more to repair than replace, and anyway I always say, if you fix it you still have a fixed thing that may have further problems, as things go. If it's new at least you can take it back.
