Question about Sharp R-1460 Microwave Oven

1 Answer

Turntable motor or support/coupler failure.

Hi, I have read many of your posts and think that you could answer my question in your sleep. Here is my problem. I bought an older sharp microwave model r1641a at a sale and it is having a problem with the carousel moving. It is turned on but still doesnt move. I watched your video on how you cantell if it is the motor by turning it, but i still cant figure out if it is the support or the motor. Is there anyway to see if the motor is working or should i just buy both pieces and replace and be safe? The support looks like it is a little chewed up inside, but nothing seems to be trying to even turn. Any suggestions for me?

    Yes - you are correct it is R1461a not1641. I appreciate all your help on this. After I read your message I took the support off and places a straw in there long enough to tell that the motor was working. When I tried to turn it by hand there was no whine and no resistance, only the sound of the rollers going around the bottom. After that I took a better look at the hole in the support and carved away the frayed edges. Then i was able to push it further down than what it had been sitting and it worked!!! Well hopefully that is all it took, I probably will go ahead and replace the support though as I have a feeling it is not going to work for too long.

    I do have another question I have been thinking about while playing around with it. When I picked this up it had no mounting plate with it. I am thinking that I may be able to come up with some kind of brackets that would hold it (of course securing it to the cabinet as well), and maybe put some kind of ledger underneath it to insure it would not go anywhere. Would that create any problems that you could forsee in doing this using a 1x2 support on the wall underneath of the unit? I am happy I got it all working correctly now and don't want to do anything to damage it.

    I sincerely appreciated your assitance the motor/support and I would have been at a loss without your suggestions!

Isn't that actually an R1461A?

When you try to turn it by hand (as in the video) do you hear the motor whine? Is there resistance? Or does it just turn freely?

The hole in the turntable support should either be round with a flat side or a cross shape. If that's damaged, it won't work.

In some cases, the legs of the support get too hot and when the weight (food) is removed, they bend downward in relation to the hub.

I have solved this problem in the past by carefully heating the area where the legs meet the hub, using a gas stove flame or a torch.

Then I place it on a flat surface, weighted down so as to hold the legs so they will cool in the correct position.

If you have to do it more than once, the support should be replaced.

You can see if the motor is turning by removing the support and placing something wooden or plastic into the hole and see if it turns when you cook.

If you replace the support or motor, you should also replace the "packing" which is a rubber grommet.

You can find an exploded view here, and the parts list is here, but the best place to order Sharp parts is Tritronics.

To replace the motor, you need to remove the bottom panel of the oven, then remove the motor screws.

    Don't forget this critical part of my solution, which should be the coveted "FixYa":

    Concerning the mounting hardware, I cannot recommend anything but standard OEM parts.

    The mounting plate is part number FANGTB001MRY0, the mounting screws are part number LX-BZB011MRE0, the installation material assembly is part number CFZK-B131MRK0, and the installation instructions are part # TINSEB371MRR0.

    If you want to order the turntable support while you're at it, it's part # FROLPB017MRK0.

    You can get all these from Tritronics and please note that these part numbers end in zero, not "oh".

    Now that should be a FixYa! Good luck and be safe.

GE model je 1860, the turn table doesn't work, the 21 v ac crossed the turn table, and the motor is 128 ohm as the spec. Would you think what caused,please Thanks


In GE / Samsungs that have 21VAC turntable motors and stirrer motors, the 21VAC is supplied from a tap off the internal cooling fan motor that cools the magnetron.

It sounds like you have a bad turntable motor.

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

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or possibly a bad plastic coupler.

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

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

The turntable doesn't rotate anymore


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 can find helpful exploded view diagrams and order parts for many brands by entering your full model number here, but if your brand is not listed, try Encompass or call them toll-free at 866-779-5835.

If neither source has parts for your model, please post a NEW inquiry here on FixYa and please include your brand name and the full model number from the tag in or on the unit, as well as mentioning that you have turntable-related trouble.

My turntable quit turning, I looked in and found a what appears to be a piece of what looks like glass that acts as a shaft between the motor and the turntable was broken. I cant find the part or any...


If you are talking about the little piece that the center of the tray sits on (not the carousel ring), its called the coupler. Its actually made of plastic on all the microwave ovens I've ever worked on. I've never seen one made of glass. It connects to the turn table motor shaft. If you post back with a complete model number, I may be able to assist you in locating a part number.

If the coupler is not physically broken, you may be identifying the wrong part as your problem. The turntable is driven by a small motor which is mounted under the bottom panel of the oven. The coupler is mounted to the shaft of the motor and the glass tray sits on the coupler.

Post back and let me know if you need a coupler, or if your motor isn't turning. You can tell by removing the glass tray and pulling straight up on the coupler. It should come off the motor shaft in one piece. If its not broken, your motor probably needs replaced.

Microve works but turntable comes & gos

If yours is intermittent 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. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

The best place to order parts for this brand is Tritronics. Or you can call them toll-free at 866-779-5835. Their Web site will be down until Jan. 2nd.

You remove the bottom cover, then there are two screws holding the motor in place.

NOTES ON REPLACING TURNTABLES & COUPLERS

Copyright 2007 by William E. Miller - MicrowaveDisplay.com

UNPLUG THE OVEN FROM THE WALL FIRST OR YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES!

Note that I am not encouraging you to work on electrical items if you are not qualified, and I assume no liability for any consequences of your decision to do so.

When replacing the turntable coupler on most models, it is necessary to loosen or remove the screws that mount the turntable motor to the bottom of the chassis.

It is usually easier to do this with the microwave oven on its right (heaviest) side because you will need two hands for alignment.

Be sure to put a towel or similar cushion on the work surface to avoid scratching the oven wrapper (oven cover) or the work surface.

It is not necessary to remove the wrapper or the wires from the turntable motor itself, but you may need to remove a small metal duct covering the turntable motor if your oven has one.

It should only be held on by one or two screws.

Although a broken coupler may come out easily or even fall out, the new coupler will not go in without at least loosening the turntable motor.

Look at the hole in the new coupler. You'll notice it has (most do have) a flat side to it. That flat side will line up with the flat side on the motor shaft.

When the old coupler is out and the motor is loose, you can ease the new coupler in the hole with one hand while turning the coupler very slightly back and forth as you gently push the motor toward it. Do not force the part in.

When the coupler has mated properly with the motor, you should feel it go in.

Be sure it's right, or you may break the new coupler or bend the mounting ears of the motor when you attempt to tighten the screws.

Reassemble in reverse order.

Non rotating lg turntable fixit try failure


Looks this model's turntable support has a coupler shaft built-in which is supposed to go down into the turntable motor hole and make contact with the turntable shaft. Is that right in your case?

So I would wonder if the turntable support has gotten bent due to heat. That's common on some models.

When you take it out and look at it from the side, are the legs straight and perpendicular to the shaft or are they bent down?

On some models, you can heat them over a stove flame, then put them on a flat surface with a weight to old them in position while they cool.

Otherwise, you'll need a new turntable support. LG / Goldstar calls this a "rotating ring".

OTR microwave turntable won't rotate


You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If not, please post your brand and model.

It's probably the motor, but possibly the coupler.

One quick check is to remove the turntable and support / roller ring and try to turn the coupler. It should be a little hard to get started, then you should hear a whirring sound, not a clicking or grinding, which would indicate a bad motor.

If the coupler turns loosely with no resistance, then it's probably bad.

Here is my text on replacing couplers, which had steps which are necessary when replacing motors. Note that if yours is a built-in model, ignore the part about turning it on its side *grin*
