Question about Sharp R-510HW Microwave Oven

1 Answer

Sharp R-510H (2004) Carousel does not turn during cook time, but is manually movable. Occasionally it moves, but only a little, not a complete turn. What can I do to fix this? I like this model overall and it would be a waste to trash it, but at the same time, would this be a reasonable (price-wise) problem to have repaired? Can you still buy carousels separately? I was not able to access the carousel mechanism inside and under the bottom of the microwave. I was able to squirt oil down the shaft.

    when you remove the tray and run the oven, does the shaft spin at all?

We have the service manual at our site and have uploaded it here to help you.

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 motor cover on the bottom of the oven.

In some models, you have to cut the motor cover off with snips, then use a screw when reassembling it.

You can order Sharp parts for this brand from Encompass here or you can call them toll-free at 866-779-5835.

Let me know if I can help further.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

You can tell if microwaves are being emitted if you get warm standing in front of it (seriously). But I wouldn't recommend that unless you want to cook yourself.

First thing that comes to mind is the door interlocks are out of adjustment or bad. Home microwave ovens are not supposed to operate like that. Some commercial models start the fan right away and run it after the cooking cycle is completed but I've never heard of a consumer model that does that.

Find your closest servicer here and have them take a look.

It's probably a bad door switch or door switch mount, probably the top one, which is the door sensing switch.

Built-in Sharp Carousel II Microwave Convection Oven died.


There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

Sharp Carousel Model R-1440 won't stop running


It may be a sticking door switch (upper or lower, not the middle one) or the mount of one of those switches may be loose, broken or out of alignment.

See these files:
http://www.microwavedisplay.com/safety.txt
http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt

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.

Then you can get to the switches.

Or it may be a sticking relay on the control board. We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

If during this unwanted operation the oven lamp, internal cooling fan, and stirrer are all stuck on, but the turntable is not on moving and the oven is not actually cooking, then I would suspect relay RY1 on the control board is stuck.

That's what I suspect in your case.
