Turntable no longer turns


posted by rahulbpatel on Dec 06, 2006


Our turntable is no longer turning. If we remove the glass tray the spindle will turn. But with the anything on it, it no longer turns.

MicrowaveSvc,

Thanks for the very detailed and insightful reply. I'm not sure if this is the same but I can turn the spindle/plastic thing inside the cabinet with my hand and get plenty of resistance. Does this mean its a weak rotor?

I have the JMC7000ADB microwave. I saw the parts diagram. Is replacing the motor a task I could attempt to do myself as a weekend DIYer. Or is this better left to an experienced service/repair person?

Thanks...

MicrowaveSvc,

Would it be worth trying to replace the motor & coupler myself or do you think it requires an experienced professional to do it?
I have the same problem.

Your problem is either a weak or slipping motor or a broken / cracked turntable coupler.

If the coupler turns loosely without actually engaging the motor, it is bad.

If the coupler is good or looks good, it's probably the motor.

One test of the motor is to firmly grab the shaft with pliers and try to gently turn it. It should turn with some resistance and make a whining sound as it turns, since it is a highly geared motor. If the motor turns very very freely - or not at all - then it is bad.

You can see an exploded diagram and order parts via the Jenn-Air (Maytag) Web site at

You will need to enter your full model, which is apparently one of the following:

JMC7000ADB
JMC7000ADQ
JMC7000ADW

Referring to the CABINET-BASE-CAVITY diagram found there, you will see:

- REF 23 motor
- REF 27 coupler

One of those is likely the culprit.

Sounds like a bad motor.

I would refer you back to my previous answer, where you'll find the link to the detailed diagram.

It's a simple job, really.
