Question about Panasonic NN-S963BF Microwave Oven

1 Answer

My turntable doesn't turn

The turntable motor was replaced and it still doesn't work. I did have a very small black piece of plastic fall out when I opened the bottom of the microwave. It's round and half the size of a dime with a short straight piece coming out. I'm wondering if this piece helps turn the turntable but the graphics on the manual are so small I can't find where this piece may have broken off of.

    Hi Catherine OConnor, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box? It would help to know this: When you open the door to the microwave -- with the turntable removed -- is there a small piece of metal or plastic that juts up from the bottom of the floor of the microwave? I need to know this.

    I tried to change the brand to kenmore Elite but it wouldn't let me. I unplugged it for five hours thinking it would reset the circuit board. It still didn't work. I ordered another motor in case that was was defective that I was trying to replace it with. Can I post a picture of the piece that fell out? I'm wondering if it's part of what turns the turntable

Sounds like the turntable drive coupling is broken. In the bottom of the microwave where your turntable is, underneath that is a small drive coupling that the motor shaft pushes into. if the motor doesn't turn or the coupling, which commonly has a D shape shaft to keep it from slipping, is broken, the tray will not turn. One quick test it to remove your tray and see if you can turn the coupling easily by hand, if you can you probably have a broken drive coupling. The turntable motor is very difficult to turn by its shaft. so if it turns easily it is probably a broke coupling. NEVER force your turntable around by hand or you can break that coupling.

The 22 seconds is the giveaway.

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.

SOURCE: we need a replacement piece

What usually breaks is the door open lever, but the prongs on the door open button may also be worn.

On a counter top model, the outer cover will need to be removed to diagnose and repair this. On an over-the-range model, only the control panel usually needs to be removed.

Please unplug the oven first.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

Once it is apart, you'll be able to see how the door open button would press against the door open lever, which would then lift up against the door latch heads (hook-like projections on the door) and the door should open.

You can find Panasonic (US) parts here. If you're not in the US, please reply back.

You can find a helpful exploded view here.

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.

SOURCE: Panosonic NN-S525BF Latch Spring Broken

You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

In most cases, the spring mount on the inner door panel breaks off, and while the ideal way to fix it is to replace that whole panel, the time, cost and labor are considerable.

It's usually easier and cheaper and just as effective to use epoxy and some kind of hardware to fashion a new spring mount.

Or if there is enough material to drill a hole for the spring, do that, install the spring, then add a dab of epoxy to cover the bottom loop of the spring where it goes through the hole you drilled.

Let the epoxy dry overnight before you close the door or use the oven.

Take the tray and the plastic piece the tray sits on out of the microwave. There is a small motor that turns the turntable. It is probably bad. You should be able to replace the motor from the bottom of the microwave. Part number is 3966820200.

My turntable has stopped turning - can anyone help please


The turntable is driven by a motor under the bottom of the cooking cavity. A plastic coupling that slides over the motor shaft, and that's what turns the turntable. In some ovens the coupling is a separate small piece that the glass tray sits on. Other models use a large wheeled plastic ring that rotates the tray.

The usual reason the turntable stops is that the coupling breaks or wears out. The motor shaft is D-shaped, and sometimes the plastic coupling cracks so it doesn't grip properly. Or the plastic wears so that the opening gets rounded and won't grip the shaft. Then even though the motor is running, the coupler doesn't turn. You can usually lift the coupling off the shaft to check it. In some ovens the coupler can only be removed by taking out the turntable motor, but that's not common.

A second possibility is that the turntable motor has failed. In most ovens there is an access panel on the bottom that comes off to get at the motor. You can check the motor with an ohmmeter across its terminals to see if it's good. (Usually I advise against trying to repair a microwave yourself, but replacing a turntable motor usually doesn't involve removing the cover. It's not a dangerous repair.)

If the motor checks OK (not showing infinite or very high resistance with an ohmmeter), you can check for power at the motor when the oven is running. This is a little more difficult because it means there will be AC line voltage present, so caution is needed. If there isn't power, it means there's some electrical problem to be solved, like a bad connection or trouble on the control circuit board.

The coupler and motor are both replaceable, although not always easy to find. Sears parts and Encompass are U.S. sources for many brand parts. You can also search online or check with appliance servicers in your area. If the problem turns out to be electrical, you should leave the servicing to a professional. Internal repairs involve hazardous voltages and possible microwave leakage if done improperly.

Depending on what you find is wrong and the cost of the parts (and labor, if you aren't able to fix it yourself), it may be more economical to replace the oven. For a basic counter-top model, it may not cost much more just to buy new, and you'd have a warranty. In the meantime, you can still use the oven, but you'll need to stop the cooking and turn the food occasionally to get even cooking.

Good luck, happy cooking, and thanks for using Fixya! If this has been helpful, please take a moment to leave a thoughtful rating.

My turntable doesn.t work because the little plastic insert is broken.


Are you referring to the carousel ring under the glass tray? Or, are you referring to the turntable coupler in the center of the oven where the tray rests? Both these parts can usually be purchased on line at any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

All these sites are reputable and have great service. Prices vary between them, so shop and compare. The first three sites I have listed include helpful exploded view parts illustrations to assist you in locating and properly identifying any parts you may need.

You do not see the turntable shaft in the center of the oven cavity rotating, you may actually have a turntable motor that has failed. The motor is attached to the center plastic piece (called a turntable shaft or coupler) under the middle of the glass tray. The following link explains how to access and replace one:

http://www.fixya.com/support/r3555716-replacing_a_turntable_motor_on_a_microwa

This is a very simple repair, that usually is not expensive. The price range will be determined by the model and manufacturer. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.
If you have any questions, or require additional assistance, please post back with your MODEL NUMBER. I hope you find this information helpful.

The turntable does not turn. How do I change the


The turntable motor can be replaced by following these steps:

1. Unplug microwave.
2. Open oven door and remove glass tray and carousel ring.
3. Locate and remove the screws holding the bottom panel (under the microwave) in place. With the screws removed, the bottom panel should open.
4. Disconnect the connector plug from the turntable motor.
5. Reach inside the oven and remove the coupler. This is the small plastic piece that the center of the glass tray sits on. You may have to gently pry up with a flat screwdriver to get it to come loose.
6. With the coupler removed, loosen the mounting screw(s) to the motor and it should easily come out from under the oven.
7. Install new motor in the reverse order of the steps I just provided.

This is a very simple repair. Ironically, I just replaced mine today. If you have any questions, or require additional assistance, please let me know. I hope this help you.

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.

Motorized turntable broke


I fixed the problem with my microwave turntable motor without having to replace it. I removed the motor from the microwave and placed it in a small vise. Using a very small flat head screwdriver I was able to pry up the four tabs holding the casing together. You may need a slightly larger screwdriver after that to bend them back out of the way so you can remove the motor cover plate. Carefully take out all the plastic gears and note their position for re-assembly. You will find that the primary gear, at the bottom of the rest of the gears is attached to the motor magnet. It has a shaft that acts as a bushing passing through the center motor magnet. On the underside it is attached to a plastic washer. This is where it breaks. The motor magnet spins free of the gear/bushing/washer assembly. I used JB Weld epoxy to glue this assembly back together and it works like brand new. Note: On mine there were four indentations on each side of the motor magnet which corresponded to little ?bumps? on the underside of the gear on top and washer on the bottom. Place all the plastic gears back into the motor in the correct order, slide on the motor cover plate and use a small cold chisel with a round end and tap hammer to bend the tabs back into place. If this worked for you please let me know ? karlet@bellsouth.net

Goldstar 1310W built in


The following parts are in the turntable system: The turntable motor, underneath the floor of the microwave; the turntable coupler, which is like a small plastic piece; the turntable support, either a three-legged or circular piece with wheels; and the glass turntable tray.

It sounds like maybe your turntable support is missing?

You can see and hear 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.

Spacemaker 1800 Turntable


If the noise goes away when you turn the turntable off, it sounds like you have a turntable drive motor that is going bad. They are fairly easy to replace and not terribly expensive. You can access the motor by leaving the oven in place and UNPLUGGED. Remove the bottom panel. You will need to remove the turntable coupler (the plastic piece that spins the glass carousel) and remove a few screws in order for the motor to come out through the bottom of the oven. There should also be a quick connect plug that plugs into the motor. The motor runs about $35 and the turntable coupler (if you wish to replace it as well), runs about $8. The part numbers are 769741 and 769278, respectively at repairclinic.com. I hope this helps you.
