Hello there The LR error on your non-spinning Maytag Neptune is usually, though
not always, accompanied either by a burn spot or a blown fuse on the
Motor Control Board.

Either way, it means just one thang: a new motor and motor control board kit are in your future.
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 www.neptunehelp.com 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 www.neptunebearing.com. 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
I too had the Lr problem on my Maytag MAH5500B. We had it fixed once when it was still under warranty but when it appeared again this summer, I was told that it would cost at least $500 to repair -- in other words, get a new one.
With nothing to lose, I simply unplugged the unit, opened the front and reset (as in pull out and re-insert) the jumpers to the control unit on the bottom right. It's been working fine since and I run it at least twice a week. I noticed that the Lr error would appear when I interrupt the wash cycle once it begins. When the error message appears, I simply unplug it, wait a few minutes and start it up again.
It is after all, a computer...and all computer could use a reset once in a while.
