Re: every thing seem to be working, but the fan don't...

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a critical file called "safety.txt" which is of vital importance. These are at our site, which is linked at our listing here on FixYa: You can order parts for Sharp models from Tritronics at

Does not cook - time counts down extremely fast

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Then let us know if the hard reset does not fix it.
and please reply back with your brand and model number so we can help you.

JVM1190 wont cook

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

Samsung MU3250W Shut down

It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

My microwave is not heating-- the control panel seems to work-- you punch in the buttons and it starts counting down the minutes, but nothing happens except for the clock to count down. The model # is...

Since the inside light and fan don't come on but the timer counts down, I would suspect first a door switch problem, or (less likely) a problem on the control panel.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa:

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid.
