I have a Kenmore Elite Microwave Model # XXXXX It seems like the unit was a little bit louder a while back and then the turntable started slow or sporadic, and finally stopped turning. I ordered a new turntable motor from Sears and installed it and it still doesn't work. Any ideas??

replacing the turntable motor
Hello, my name is XXXXX XXXXX X am here to assist you. Okay, you ordered a new motor and it does not work. There is ONLY one input to the motor and it is 120vac directly from the control board. You can turn this on by pressing the turntable on off button. So, if you replaced the motor and still does not turn then push to turn on the turntable and if it doesn't come on then you will need to replace the control board. You can order the control board at SearsPartsDirect.com. Just be warned sometimes the price for a new control board can be around $200. Hope this helps and thank your for your time and patience, Randy.
i don't think my model comes with the turntable on/off option. at least, i've never seen it and a blogger stated earlier in a forum that this particular model doesn't have that option. I can run downstairs and check again if you think i should.
If you don't think you have one then no need to check and that will definitely tell you that it is the control board.
just curious...why is the turntable the only thing affected. something is definitely wrong with the previous motor. When I put the turning ring over the shaft and turn, it clicks and moves pretty freely. When i do the same to the new motor, it makes the whirring noise one would expect. I bought a low end ohmmeter at Home Depot to test components, but I am very electrician terminology challenged. i thought maybe the diode or transformer, but can't figure out really how to test them with the ohmmeter.
Okay, can you test for voltage with your meter and do you feel safe testing for voltage?
By the when you say turn it do you mean by hand and it moves?
yes. but because of its "beginner" status, it may not be able to test high readings.
Okay, the motor turning by hand should not turn freely. That type if motor is called an asynchronous motor and has several gears inside. You should feel the whirring and a little resistance. The only 100% true way to test to see if it is the motor or the board is to disconnect the 2 wires going to the motor and plug your leads in to the 2 wires. Then turn on the microwave and see if you get 120vac.
i'm going to run downstairs and try that test. i will be back in a few minutes. hope you don't mind my ignorance on this matter. brb
Not at all, that is what you came here for.
since i'm unfamiliar with the gadget i tried it on an electrical outlet and it registered 122. on the lead wires for the turntable motor it read 23.5
Okay so you are saying that the wires to the motor read 23.5 vac?
it read 23.5 after i plugged my meter into a regular household outlet and got a 122 reading. i'm assuming that is vac
Okay, so when you plugged your meter in to an outlet you got 120 which is what you are suppose to get and when you plugged the meter in to the wires going to the motor you got 23.5 am I correct now?
yes. now i had unplugged the wires from the motor to conduct the test. i put a probe in each of the poles of the motor wire plastic connector
That is the correct thing to do then turn on the microwave and see if you get 120vac. If not then your problem is definitely the control board and would need replacing to correct your problem. Let me know how it goes.
and that would be call the power control board, controller or control panel. all 3 show up on the diagram . i'm assuming it is the motherboard looking thing on the backside of the microwaves controls like on/off, popcorn etc..
Absolutely correct but to be 1000% sure send me the model number with the period after the third number and I will pull up a diagram to double check.
Okay, sorry about the delay. I am sending you a link to a diagram and the board you need to replace is #2006 on the diagram. Again great job and thank you for your time and extreme patience, Randy.
