Question about Maytag Neptune MAH5500B Front Load Washer
I just found the troubleshooting guide for my washer.My washer would start, begin to wash ok then after spin cycle I received error message Lr
Locked Rotor.If I hit start it would start up again then set Lr code.
The washer just began to leak water from underneath also after about 10 Minutes of use, slight puddle.
It says to check the MOTOR DRIVE SYSTEM. It could be either the motor or the motor control board. I did not preform the entire test yet.
I`am thinking it may be the motor control board, Can anyone possibly help me out?
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.

Tips for a great answer:
The LR code means "locked rotor" which is just a way of saying the control is not seeing the motor turning.
The image below contains the wiring diagram for this washer as you requested but there are some other things to consider.
Usually when the LR code is displayed the motor has stopped turning for some reason. By definition the LR code means the control has tried to turn the motor but was unable to.
The error code can be caused by to large of load, to much soap/suds in the water or a problem with the spin bearing. The cause of the LR message can be little problem like suds or a major problem like the spin bearing and sometimes it's difficult to pin down. You don't mention in your question if the LR code occurs every load or once a week.
More information on when the error is occurring would be helpful resolving this problem. Try running a rinse and spin cycle empty and see if the washer completes the cycle.
The 2nd image contains the information on how to enter and run a diagnostic cycle which may help pin the source of the problem down. This test completes all functions of the washer is a short time. It will fill, tumble, drain and spin all is a few minutes. At the end of a successful test cycle a PA should display which means "Passed" and is what you want to see.
