I am getting a code on the display of Lr The Machine goes Through the timed cycle and fills with water and empties but does not wash or spin. I suspect the motor control or the motor. Are there any procedure to isolate the problem?
Answer Hello David. The motor drive system experienced a momentary loss of neutral feed from the power cord to the
Motor Control Board. The neutral line for the Motor Control Board passes across the water valve
solenoids. Neutral to the motor drive system can be momentarily lost If there is poor crimping of any
of the wire terminals in this circuit. This situation could result in a misdiagnosis and unnecessary
replacement of the Motor or Motor Controller Board.
Current Neptune front load washers will indicate a false locked rotor signal to the Machine Control
Board. Washers with a LED display will flash code “LR” in the display. LCD washers will display
“Locked Rotor.” The earlier built front loaders will not display a code, but simply shut down in mid-cycle or will not start. Pull each terminal of the white wire harness connected to each water valve solenoid and verify the
wire is properly stripped and crimped to the metal terminal connector of the wire harness. Make sure
the wires fit snug on the terminals of the water valve solenoids.
Washer will rotate drum, shows the door lock is locked, but will not go in to spin.
Answer Hello Gail. You will need to test the balance switches on the unit and check the spin enable switch. Also, look for bad wiring going to the balance switches. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Our washer 11 years old was noisy and wasn't spinning or draining water. What that could be the cause of ... Motor ?
Answer Bozena, Check the drain pump 25001052 and drain hoses first. If the washer doesn't drain all the water out, it won't spin. The noise could be a worn out motor bearing, or something in the pump causing it to fail.
How do you replace MAH4000AWW motor?
Answer Hello Aud3946. The drive motor is hinged into the left bottom
area of the outer tub and secured to the outer
tub by the bolt on the belt adjustment wheel.
A slot in the mounting bracket of the outer
tub allows the motor to pivot and allows
adjustment of the drive belt tension. 1 . Disconnect power to the unit.
2 . Remove the front panel, rear access panel
and the front weight. 3 . From the rear, locate the belt adjustment
wheel and note the adjustment number
aligned with the rib of the outer tub. This
will help later when the belt adjustment
wheel is placed back onto the outer tub
and the belt is remounted on the motor
and drive pulley. Remove the bolt securing
the belt adjustment wheel. 4. Lift the motor slightly to disengage the belt
from the motor pulley. Place motor on the
base frame. 5 . From the front, remove the wire harnesses
from the back of the motor.
6 . Grasp the motor and slide it carefully from
the pivot hang holes in the outer tub. 1 . Reverse the previous procedures to remount
NOTE: Prior to hanging the motor, reconnect
motor wire harnesses and ground wire.
2 . Prior to hanging the motor on the outer
tub, check the positioning of the rubber
3 . Check belt tension. If loose, loosen the belt
adjustment wheel bolt and rotate the
wheel one notch in a clockwise rotation.
Check belt tension again. The belt should
experience no more than a 1" deflection
when depressed to the inside.
My washer makes a loud whinning noise in the spin cycle. What could be the cause?
This could be either the motor or the spin bearing. The first thing to do is open the door and reach up and put your hand on the top of the inner tub. Push up and release several times lightly. If you feel play and hear a clunking while doing this, the spin bearing 22004465 is at fault. If it feels tight with no play or sound, the problem is probably the motor 12002039.
