    tzweeb, Thank (((you)))! Right on the money! I did call Maytag as you suggested and was told that since the machine IS over 5 years old, they will not 'help.' My serviceman (who verified your diagnosis) called the local parts dealer; the part was in stock; the price is $l90. Again, thank you SO much for your help. Allow me to wish you a sparkling day!

Maytag neptune washers do have a motor problem and they have a kit to replace the motor and motor controller.
when the motor fails, it wont wash or spin. most units have a 5 year parts warranty and should be replaced with a free part, but you will have to pay an authorized servicer to do this.
if it is over 5 years then i would call maytag and see if they will help you with an authorization for repair.
most of the time they will provide the part for free. just call the 800 # and ask for help. they wont send you the part but might give you some help with the parts.

the LR code means "Locked Rotor". when this happens the cause is one of two items. 1) the circuit board at the top of the unit has lost connection to the motor and its control board at the bottom (connector loose) or 2) the motor and or control board at the bottom have trashed and need to be replaced (P/N 12002039).

At the spin cycle it shuts dwn and has Lr on the screen when I shut it off to just use spin cycle it does a count down but not the spin then Lr comes up again


Thanks for using FixYa. Lr means locked rotor. This issue occurs due to locked rotors, you'll need to check the rotor wiring and 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. A little power surge can damage the boards.
Please do rate the solution and revert for further assistance.

Usually, the LR or 'Locked Rotor' indicates a problem with the motor / motor control board or MBC. The MBC is located near the floor on the right side. See for disassembly photos. The original MCB's had a high failure rate so Maytag redesigned the MCB and the motor. The motor conversion kit is part number 12002039, which includes the new motor, MCB, harness and takes about an hour to install. You can inspect the MCB for either a blown 10 amp fuse or if you see components that are burnt or discolored. If either of these is the case then you will need the motor conversion kit.

In addition, as your Neptune ages you might notice the spin cycle getting louder to where it will sound like a jet plane taking off. If this is the case then you can replace your bearings and seal kit. See You can also rent a special Neptune bearing tool called the tony tool which includes the use of a DVD that shows you how to take apart Neptune, replace bearings and install the 12002022 seal kit. I hope this helps...

lr is a code for a locked rotor assy, on the motor itself, depending on age of machine you might have warr on the motor(part anyway) check your user guide and warr info. probably gonna need to install a "neptune repair kit" which includes new motor and new motor controller
