Question about Kenmore 3.8 cu. ft. HE4t Front Load Washer

3 Answers

F07 occurs at end of first rinse cycle

HE4T - checked motor windings, 5.95, 5.95, 5.56 ohms
My assumption is the 5.56 is OK.
All wires are connected and seem secure at MCU, CCU and Motor
I do not know how to, or if I can test the MCU.

After testing connections I ran an express wash and got F07 at end of first spin.
Then ran just Drain and Spin at Highest Spin setting. Runs 12 minutes with abouot 4 spins and failed with F07 at the very last minute.

I don't know if this helps but I had this fault F07 on my Whirlpool AWOD6727 and it happened when empty. Since then I have had the F06 code and not spinning. I traced this fault to worn motor brushes. Changed both carbon brushes for 20 pound and it works wonders no more F07 or F06 a cheap and simple option too. Good luck Steve

F07 - Motor Control Unit (MCU) Error - Disconnect power and unplug unit. Check wire harness connections between drive motor and Motor Control Unit (MCU), and between MCU and the Central Control Unit (CCU). Reconnect power and plug unit in.
Check the MCU by looking for operations of the drive motor, and check drive motor for powered rotations. Replace failed component.

Note: If this failure occurs during high-speed spin, the door will be unlocked after three minutes.

My Roper washing machine will not complete a cycle. It stops before it gets to rinse. If I turn it off and wait a few hours, it will run and finish if I waited long enough. Could the motor be dying?

58.
The ohmmeter should show an open circuit when each of the wires (terminals)are checked. If not, the drive motor is bad and needs replacing.


HOW TO live TEST a G.E - MOTOR

After removing the cabinet follow the wires from the motor halfway up the tub. Then cut and splice the ORANGE, the BLUE, the VIOLET /WHITE, & the RED wires.
Now using a long long extension cord with the end connector cut off and exposing the 2 end wires stripped back about an inch.

To check the spin cycle: Connect and splice the RED & the Blue wires to one end of the extension cord wire. And the ORANGE & WHITE /VIOLET to the other end of extension cord, be sure to use but connectors or electrical tape. Plug in the cord an the wash cycle should start? If not the motor is bad.

To check the wash cycle: Connect the BLUE and the WHITE/VIOLET wires to one end of cord. And the ORANGE & RED connected to the other end of cord, then plug in and the wash cycle should start? If not the motor is bad.

By the way my advice is free cuz God is good!

Error code f 07 mid cycle?!?


You do not state your machine or model. The error code F07 that I have states that the Central Control Unit has detected a short in the Motor Control Unit.
Check the wire harness between the Drive Motor and the MCU and between the MCU and the CCU.
Check the MCU.
Check the Drive Motor.
Check the entire wire harness.

Replace any defective parts.

Error f07


F07:

Motor Control Unit Error

The Central Control Unit has detected a short in the motor control unit. If a failure occurs during high-speed spin the door will be unlocked after 3 minutes.

Potential Causes

Check wire harness connections between the Drive Motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU)

Check the MCU • Check the Drive Motor • Check the Wire Harness

Sears Calypso .... Error code C1 or CI came on and machine struggles through finishing the rinse & spin cycle on smaller loads in the delicate cycle? Any ideas? Bigger loads are no problem. happen...


C1 occures when there is a spike of 25 amps or more on the motor windings. This can be caused by overloading, the drive motor itself or the motor controller. You need to do some tests on the motor windings to see if they are in spec. Easiest way is on the board. Using a putty knife, slide it under each end of the consol and press on the spring. Push up on the consol while pushing in. The consol will lift up. The motor contoller board is on the left. The P6 harness is in the center. With the washer unplugged, unplug the P6 harness. Measurements on the harness should read: From the red wire to white/black=3.1 ohms. From yellow to white/black=2.8 ohms. From red to yellow=5.9 ohms. Or if you want to read them direct at the motor. Remove the harness and at the motor, red to white=3.1, yellow to white=2.8, red to yellow=5.9. If you have a reading that is much higher than the posted a problem exists in the motor windings. If they check ok, then the problem is in the motor controller. It's up to you but I sure wouldn't put any money in this machine. It has been my experience that there is just too many failures on this model. Catriver.

Whirlpool awm 8143 doesn't stop at the end of the spin cycle. Instead it clicks for a while when the timer displays 1 minute then displays F07 then goes back to wash cycle. While googling I found something...


F07 - Motor Control Unit (MCU) Error - Disconnect power and unplug unit. Check wire harness connections between drive motor and Motor Control Unit (MCU), and between MCU and the Central Control Unit (CCU). Reconnect power and plug unit in.
Check the MCU by looking for operations of the drive motor, and check drive motor for powered rotations. Replace failed component.

Kenmore HE4T elite: Incomplete F 06 error


The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 - is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.

NOTE: All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.
