Maytag washing machine model mah5500bww is displaing an Lr code. Does this mean I have to replace the motor?
it is a problem with the motor .this is confirmed.
Issue Washer stops in mid-cycle and/or flashes a code.
Warranty Standard product manufacturing warranty applies.
Action 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 midcycle
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.
A product improvement has been made to the following models. The neutral wire is routed across
the pump only, and now by passes the water valve solenoids.

Hi
Lr means locked rotor,
this issue occurs due to locked rotors, you'll need to check the rotor wiring
and motor windings. If the wiring is good and windings are not burnt then
you'll need to replace your motor and motor control board. These are sold as one
unit, it is a 3 phase motor and one of the phases is bad as a little power
surge can damage the boards. Hope
this helps...please post back for further assistance.
