Tip & How-To about Maytag MAH6700AWW Neptune Front-Load Washer

Maytag Neptune Front Load Washer Shutting Down in the Middle of the C ycle

One of the common troubles experienced with Maytag Neptune Front Load Washers is the shutting down of the washer in the middle of the cycle intermittently or permanently. Later models with display will show a code "Lr or "Locked Rotor" signifying that no tach signal is detected by the machine control from the motor control. Earlier models will not display a code, but simply shut down and will not start.

The typical troubleshooting of the cause of the problem is by checking and ensuring the continuity of the connection between the machine control and the motor control. When the connection is good and the problem is not resolved, the motor winding is checked for continuity and the motor control is checked for component physical damage; such as blown fuse or burned semiconductor components.

The disappointing and frustrating scenario is when the motor windings are found to be okay and the motor control is apparently the cause of the problem; but the problem is not resolved when it is replaced. Typical troubleshooting suggests the machine control be replaced too; but the washer still does not want to start.

What is not well known is that the neutral line for the motor control is routed to the water valve solenoid terminals, not to the machine control. This connection must also be checked for continuity when such problem is experienced. Poor crimping of the wires to any the water valve solenoid neutral terminals may cause momentary loss of neutral feed from the power cord and result to the shutting down of the washer in the middle of the cycle.

Disconnect each of the white wire harness connected to each water valve solenoid and verify that the wire is proper stripped and crimped to the metal terminal connector of the wire harness. Make sure the wires fit snug on the terminals of the valve solenoids.

Keep getting Lr halts with even the lightest loads. Takes hours to do one load restarting, adjusting, restarting.


This is a common issue with earlier Maytag Neptune Front Load Washers due to a momentary loss of motor control neutral feed from the power cord and result to the shutting down of the washer in the middle of the cycle. The neutral feed line needs to be checked for poor connection. Check the tip I posted regarding this problem and how to address it.

im having trouble with my maytag neptune tl washer it wont finish the spin cycle


Please see the following Whirlpool / Maytag service manual for Neptune washers.
https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/dc59d905140253e18525729c005765f4/$FILE/Maytag_Neptune_Washer.pdf

On page 3-1 the manual explains that if the washer shuts off during the spin cycle, the problem points to a weak spring in the door lock mechanism.

"Shuts OFF In The Middle Of The Spin Cycle:
During the spin cycle, the machine control
monitors the door lock mechanism to ensure
the door is locked. This is done through the
door lock enable switch. During "lock mode,"
the shaft of the door lock mechanism is
pressed forward by the door lock wax motor,
and the shaft presses in the button of the door
lock enable switch. If the machine control
board sees the switch OPEN during the spin
cycle, the machine control board will automatically
shut the washer OFF. This is caused
by a weak spring in the door lock wax motor.
Replace the complete door lock mechanism.
