Sounds like an electrolytic blew, but it could be any nuber i=of things. Usually when one element fails, others are damaged and are failing as well, such as the magnetron.
If it is an inexpensive table-top microwave, it would be less expensive to replace it with a new one.

SOURCE: My Sharp R-340D microwave works perfectly but Does NOT HEAT FOOD

Waleed, Since the microwave is going through all its motions we can feel safe that the oven and magnetron thermostats are ok. If they were bad you would not have a display. Just inside the control panel to the left, you have 3 switches which the door activates. A primary (top switch) a secondary (bottom switch) and a monitor switch (middle). If the primary or secondary switch is not closing when the door is shut, you high voltage side will not activate, therefore no heat. If the monitor switch failed or found either the primary or secondary switch closed with the door open, it would blow the main fuse and the oven would be dead. Therefore Im leaning on either the primary or secondary switch not operating correctly. When checking these switches, unplug and discharge the capacitor. This is high voltage. Good luck

SOURCE: Microwave makes a loud noise while using.

After you turn it on, it's a loud noise like it's coming from the fan, but other then that it works wonderfully.

SOURCE: microwave light door turn table works but does not heat up food

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

SOURCE: Error code ee1 on sharp r-22at

EE1 on a Sharp commercial microwave is magnetron 1-related failure.

It may be a bad connection or relay on the control board, a bad magnetron, a bad high voltage diode, etc. - anything in the high voltage circuit for the #1 magnetron.

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

It will give you safety info, step by step help in disassembly and troubleshooting tips, but do not rely on the part numbers shown in that manual.

You can find part numbers and order parts from Encompass here or you can call them toll-free at 866-779-5835.

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

SOURCE: sharp carousel II microwave/convection oven

Hello, I just purchased a Sharp Carousell II convection microwave oven, also built in 1990, serial number 212806. I think the model number is R18244, but part of it is worn off. Can anyone tell me how to get a manual for it? I have never cooked with a convection oven before.
Thanks

How to fix loud hum and no heating in Sharp model R-308KW?


Hi,
There could be a variety of reasons why this happens, but the likeliest
reason is the secondary interlock or monitor switch is broken. These are micro switches that tell the microwave that the door is closed. If this switch is broken, then the microwave thinks the door is still open and the carousel table won't turn, and the oven will not heat up.
I replaced an interlock switch last Saturday. The switch was $7.00 and took me an hour.
Ask your local repair person to test the interlock and monitor switches first, then go from there.
Good luck,
Hank

I have a sharp R 350 l. when i switched it on to heat some food it ran for about 10 secs then a loud bang.All functions work except that it wont heat anything.


Sounds like an electrolytic blew, but it could be any number of things. (Failure of one element could cause the failure of others, such as the magnetron, as well.) You could have it looked at, but if it's an inexpensive table-top microwave, it's less expensive to just go buy another.

I hv a 24ltr Sharp Carasoul Microwave. Few days back, its plate stopped working, but its heating the food fine. Why has the plate stopped rotating? Will the food be evenly heated even though the plate...


> Why has the plate stopped rotating?

The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You order Sharp parts Encompass here or call them toll-free at 866-779-5835.

> Will the food be evenly heated even though the plate is not rotating?

No.

Sharp carousel microwave model # 508ak has power but does not heat food when you press the start button. thanks in advance!


9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section. Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....

Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
thanks.

Sharp microwave losing cooking power


If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

I would say the high voltage diode blew.

If you or a friend decide to look into it, we have critical safety and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

You can get Sharp parts from Tritronics at http://www.wehaveparts.com

If it's not the high voltage diode, reply back for further help.
