    The motor that spins the wash tube does not come on. I have a new door latch. I have tested the motor fields for resistance and found very low readings. I have no power between the pins 2 & 4 of the four pin plug that connects to the Speed Control board. I have failures of every test after that as referenced on the tech sheet that was in the machine. I am trying to determine with certainty whether the motor has failed or the Speed Control board has failed. What should I do?

    Is there a way to check just the motor?
    Is there a way to check the speed control circuit board?

  • dfreeh Jan 28, 2009

    Regarding the motor. I removed and with an Ohm meter and the wiring diagram i found low resistance readings across the various windings, except one which is labeled "tacho generator" on the diagram.
    Also, there is a separate motor plug having two wires that per the color coding are connected to the "motor protector". I think this is inside the motor. While get a .2 ohm resistance ready on my ohm meter, when the power is plugged in I don't any voltage at these connections.
    I am leaning motor replacement, but is there a way to determine if the speed control board is shot?

  • dfreeh Jan 28, 2009

    Actually, the tech sheet diagram is pretty good and I can identify the wires that should have power at different times in the cycle.
    I believe that your idea could answer my question.

    Thanks, I will let you know if this worked.

  • dfreeh Jan 31, 2009

    I disconnected the wire plugs to the motor. I moved the timer through the cycles test for power to the motor. I only found power at connection to motor protector. So i replaced the speed control board. The machine is still not spinning. Can it anything other than the motor?

I have a question for you. why would you change a motor if you cant get power to it? I'm in search of a diagram now but what I would do is determine the power wires going into the motor and trace them back until I found power whne you find power youv'e found the faulty component wether its a control board or relay or whatever. if you had a bad  coupling the motor would operate.

I believe that the situation may be faulty wiring for sure. I would contact a professional to come out and take a look at it for you. But you dont have to do that if you believe that you can figure it out yourself. I would like to say that if it is faulty wiring, that could be a costly repair. Sorry for the trouble that your system has caused you.

It is probably the motor, not the speed control, unless you have already tested the motor.

Let me know what you've tried and I'll provide further information.

    Remove the motor.

    Take a look at the wiring diagram and you can determine which connections are for neutral, forward, backwards and any run capacitors. Connect any run capacitors that are a part of the circuit, connect neutral to a line neutral, and then connect to either the forward, or the backward terminal (but not both at the same time.).

  • Mark Egan Jan 28, 2009

    Another way to test the control board is to figure out which wires run the motor from the wiring diagram, and hook a voltmeter up to the low speed connection, then high speed connections, and run the timer through it's cycles. If you get power when your supposed to, then chances are the motor is at fault. If you don't get power when your supposed to, the controller board is at fault.

    This unit has that weird Siemens motor on it, so it may take some more digging to identify a connection diagram for testing, other than the wiring diagram on the unit.


  • Mark Egan Jan 28, 2009

    You won't measure voltage across the protector. It should always be closed, and only opens in case of a fault (and when faulted is when you would measure voltage across it). So the protector is good (Just look at it as though it was a piece of wire).



  • Mark Egan Jan 28, 2009

    Thanks! Glad to be of help, and let me know what the outcome is. If you have any further questions, please don't hesitate to ask.

It sounds like an out of balance load was trying to spin out. Try putting the washer in spin with an empty load to see if you get a high speed spin. If you do, then be sure the loads are evenly balanced. If the washer controls sense an out of balance load the unit will not go into a high spin speed, this is done as a safety feature to prevent the unit from walking or damaging internal components. One or two items will not work good for this style washer. Other possibilities would be; loose drive belt, worn bearings, speed switch, timer or motor.

  1. Did you notice any black sooty shavings under the center of the washer, If so the drive coupling is worn or broken.
  2. Check the timer.
  3. Check for power at the relay

You have to take the top off... 2 screws, under the lint filter. Then thin bladed putty knife, about 1-2 in from the sides, push in, lift, tilts back.

2 screws, hold on the front, tilts down, drum kinda falls out. If you're mechanically inclined, you'll figure it out from there.

If not, let us know we can talk you thru some more. Look on web, exploded diagrams, use your model number in the search on google.

Belt wraps around the drum, and a spring-loaded tensioner to keep it tight.

Make sure the unit is unplugged before you start,

Look at the motor coupling. take off the front and then pull the pump. then pull the motor. The coupler is on the shaft and is probably you problem, usually that will go long before a motor. about a $10-$20 part.

The machine doesn't spin properly and doesn't drain the water


see this causes and fix it. God bless you
Lid Switch Assembly If the washer won't spin the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Motor Coupling If the washer won't spin the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission. Another common problem is the lid switch.

Drive Belt If the washer won't spin, check the drive belt. If the belt is broken or if it isn't tight on the pulleys the washer won't spin properly.

Door Lock Motor and Switch Assembly If the washer spin the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Motor Control Board If the washer won't spin the motor control board might be defective. The motor control board provides power to the motor as well as direction and force. If the motor control board is defective the washer may not work at all or function properly.

Drive Block If the washer won't spin the drive block might be worn out or may have come loose. Underneath the agitator the drive block connects the inner tub (the one that spins around) to the transmission. If the drive block wears out the transmission shaft will still spin but the tub may not - or it may spin slowly. This also usually causes a lot of noise. The drive block is relatively easy to replace.

Clutch Assembly If the washer won't spin, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may prevent the tub from spinning. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.

Clutch Band kit If the washer won't spin, the clutch band kit might be worn out. The clutch makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may prevent the tub from spinning. If the washer won't spin, this clutch band kit may need to be replaced.

Drive Motor If the washer won't spin the drive motor might be defective. This is not common. Check all of the other related parts to this symptom before replacing the motor. If the motor is visibly burned out or physically damaged It will have to be replaced.

Tub Bearing If the washer won't spin the tub bearing might have seized. This is a common problem and relatively easy to replace.

Tub Seal and Bearing Kit If the washer won't spin the tub seal and bearing might have seized. This is a common problem and relatively easy to replace.

Bearing If the washer won't spin the bearing might have seized. This is not common. The bearing doesn't require any normal maintenance. They generally go bad when the tub seal fails and allows water to leak past into the bearing.
Basket Drive If the washer won't spin the basket drive clutch might be worn out. The basket drive sits on top of the transmission and engages with the inner tub. If the basket drive wears out the tub won't spin.

Basket Drive Hub Kit If the washer won't spin the basket drive hub might be worn out. The hub is a set of plastic gears underneath the agitator. The basket drive hub kit is easy to replace with standard hand tools.
Transmission If the washer won't spin the transmission might be worn out or defective. There are numerous more likely causes when a washer won't spin, which should be checked first.

Kenmore HE3


Terry, here's the fault definition and the checks/repairs for it... F/06; Drive Motor Tachometer Error "The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes." Check/Repair; * Check wire harness connections between the Drive Motor/Tachometer and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU) * Check the Drive Motor * Check the MCU * Check the Wire Harness If you can next time, please provide the entire model number in your post so we can help a bit more. Kenmore doesn't actually manufacture anything, they purchase their units from manufacturers and slap the Kenmore label on them. The model number is located just inside the door on the frame of the unit.

My HE3 kenmore washer is dsiplaying 11f error code


Hi,

F11 is a serial communication error. Communication between the main board and the motor control board is not being sent correctly. This could be a bad main board, motor control board or motor itself. The testing can get pretty involved. Try putting the machine in a self test mode and see if the error clears. Press Cancel, then by pressing the drain spin button once on the left side then move to the spin speed button the the right. Press this button until no-spin lights. Press the prewash button 4 times. C00 should appear in the display. Let it run it's tests, there will be 8 of them and end up on C08.


Thank you !!

My fridaire front load washer will not spin at high speed


HI. Your unit is equipped with a Motor Speed Control Board. This board regulates the spin speed, with the help of a tachometer, which, is located and mounted on the motor. When this Control board is experiencing issues, the spin will not preform at optimal performance. I recommend to replace this Motor Control Board asap. Once replaced, the unit will spin properly.

I have a Kenmore frontloading washer, model no. 417.42042100. At the end of the wash cycle, the clothes are still very wet; that is, still SOAKED with water, even though all the water has been drained...


HI. your unit is equipped with a spin control board. this board, if damaged, will not initiate an adequate spin. This will not allow for proper drainage and drying of the clothes. The spin motor regulates the rotation speed during the spin cycle. It seems to be the culprit at this time. Have the spin board replaced asap.

This part will usually cost around $150.00 at the most.

He 3t error code f6,washer will not spin,door will not open


"f6" error code means that there a miss communication between mcu(motor speed control board) and ccu(central control unit). i recommend you to ohm out the motor. most likely its your motor speed control located at the bottom left of the washer good luck. replace the motor speed control board and you should be all set to go.
