    Mine is a Sharp Carousel R-1514 1000 watts. The noise that the microwave makes is unusual. Its like a deeper pitch of the regular noise. The lights come on and the turntable turns and I can set reheat, defrost, or cook time. It just will run, but not heatup anything.



    Thanks

    Sharp Carousel R-1501: Unusual loud noise; turntable & light work; doesn't heat. Magnetron?

  • Anonymous May 14, 2009

    I have a Sharp Carousel Model R395f(s), got it as a wedding present about 15months ago. Oven works perfectly except it doesn't heat anything. No weird noises, all buttons work, the interior light works while the oven is in operation and the turntable works.

    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?

    These answers will help me judge whether it's in the high voltage
    section (magnetron, transformer, or diode) or the control section
    (door switch or control board relay or connection).

    My Sharp Carousel does not work. All the buttons and light work, but the turntable does not work so the food does not cook.

SOURCE: R-4H84 Sharp Carousel II microwave oven stoped working

A microwave can be dead for many reasons.

The fuse is normally located on the floor of the chassis behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

SOURCE: Samsung microwave doesn't heat food.

Microwave ovens that do not heat, and failed as you have described, have 1 or more of the following failed components, in order of cost -

1) Fuse
2) Diode
3) Capacitor
4) Transformer
5) Magnetron

4 and 5 are interchangeable when it comes to cost.

Try replacing 1 and 2, then 3, then it's decision time of whether to buy parts or replace the microwave.

SOURCE: Where is the light bulb in an old Sharp Carousel Microwave?

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

The service manual (available at our site) shows how and shows that the lamp is mounted in the air duct near the magnetron. See http://www.microwavedisplay.com/r510hk_hw_sm.pdf

Part # is RLMPTA086WRZZ and you should be able to get that generically locally but if not, you can get it form Tritronics at http://www.wehaveparts.com

SOURCE: Microwave touch pad work light doesn't work

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

Maybe. The presence of metallic material (foil, stainless steel silverware, etc.) in an operating microwave oven creates electric arcs between the foil and the inside wall of the oven. And this can destroy the electric components.

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 R-340H Microwave has power but does not heat food. Carousel working.


The magnetron is the likely problem, "heats food" the other two items to check is the high voltage capacitor and diode. It usually is cheaper to replace.

It's not getting heat and LCD looks like there's water inside.


On most Sharp Carousel Microwaves, the display stops working after time. As for the not getting any heat, the magnetron or the high voltage transformer may not be working.

Sharp carousel r-508ak - does not heat up the food

Sharp Carousel Microwave Model R520-LK timer will run but carousel doesn't turn and food doesn't heat.


I also have the Sharp Carosoul oven, symptoms - fan runs, controls are fine but the turntable stopped turning and it did not heat. It was not the switches, fuse, but in fact a sagging door that misaligned with the door switches. The true cause was a warn top hinge. As a temporary fix, I adjusted the bottom hinge (3 screws underneath), straightened the door, and now it works again.

I always recommend that folks put food off-center on the turntable 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.

 

The turntable generally replaces the stirrer, which actually scrambles and stirs the microwaves as they come out of the waveguide from the magnetron. But some models, notably GE's, have both.

 

So if you're placing the food properly and it's still burning, since it's under warranty, contact Sharp at 1-800-BE-SHARP (1-800-237-4277) to see about getting it checked.
