Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

It may be a food placement issue or possibly a bad humidity sensor.

I always recommend that folks put food off-center on the turntable (not in the center) to assure more even heating.

It's a stirring action, so imagine how inefficient it would be to stir just by twirling a spoon in the center of your coffee!

Also, when you put your food off-center, you're not putting it in the same spot every time. That will help prevent repeated heating of the the same spot on the glass, which can lead to weakness and cracking. Microwave popcorn gets hot enough to do that.

We have the entire service manual at our site if your or a friend want to look that over: http://www.microwavedisplay.com/r820bc_bk_bw_sm.pdf

If you need a new sensor, you can order Sharp parts from Tritronics at http://www.wehaveparts.com

Assuming your inside light and turntable come on when you try to microwave, with the symptoms you have, I would most strongly suspect a bad magnetron or a loose and possibly corroded connection on the magnetron's terminal.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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'sprobably okay)

The best place to order parts for this brand is Encompass (formerly Tritronics).

Or you can call them toll-free at 866-779-5835.

SOURCE: I have a Sharp R-930AK microwave oven. Not heating

That would be a problem with the secondary interlock (lower door switch) or its mount.

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 the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

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

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Most computers will open this document automatically, but you may need the free Adobe Reader

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

You can order other parts from Encompass here or you can call them toll-free at 866-779-5835.

My sharp carousel II microwave no longer heats food. Do I need to buy a new one?


The problem maybe the magnetron, or the inverter board if 7 years old or less, and possibly the keypad control board, by the time you add parts and labour cheaper to replace the microwave oven in the long run.

Sharp 1200w microwave seems to be tripping lightly (can hear clicking noises)and cause heating to be irregular


Clean the food off the inside top of the microwave Now,Or that noise you are hear will stop along with the microwave. The food gets on the Formica Squire which is how the micro waves heat your food. 1st unplug the Microwave then spray the inside of the unit with something like Fantastic or something strong and use glove so you don't burn you hand,Also if you have a scrub brush use it,And clean all the soap out and raise very well.

Comes on but it wont heat up


Mine just started doing this... pushing on the left side of the drawer results in a "click", and then it will actually work. I suspect there is a switch/contact in there that is worn/malfunctioning, but am still researching it.

Crackling and popping sounds when you heat up food


thats normal water expanding and boiling off from the microwave boiling those tiny water pockets in food... sounds like popcorn sometimes.
Cover your food with a paper towel to avoid spatter on the ceiling of the microwave when this is happening.

Motor 'Dragging'


The motor run's the same speed regardless of power setting.

If 1000 wats is too much for your poor old electric service, then you better not use your A/C.

As for checking voltage, you need to measure the voltage at the plug with the microwave operating.

Convection oven problem


Most of the time the magnetron is defective if the food is not heating up.
In some cases there is a defective low power transformer or other componenents associated with the magnetron.
I would suggest to check the owners manual under the warranty section. Sometimes the magnetron has 5 years warranty.
Good Luck.
