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.

Maytag upgraded the motor and motor control board because this problem was so prevalent. Big rash of these a few years back... and insludes replacement instructions with the kit.


The LR code means "locked rotor" - 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.

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.

From another source...

"Installing replacement motor, motor control harness, and motor control circut board.

Pretty easy install. On a scale of 1 to 10 I'd call it a 3.5.

If you can use a screwdriver, a wrench, and have played with legos before, you can probably do this job.

It took me about 3 hours to do, but this was with inferior tools, and two smoke breaks included.

Minimum tool requirements: Adjustable-head cresent wrench (8 or smaller handle), phillips head screwdriver, utility knife.

Recommended tool equirements: Small ratchet with socket set, ratcheting screwdriver with phillips head and small socket attachments, brew.

The instructions are pretty clear.
Once you pull the front panel off, there are two braces at 45 degree angles on the lower corners of the washer.
The instructions don't ask you to, but I would remove the brace on the left to make life easier.
This gives your arm more room to work and makes it easier to pull the motor out the front.

They ask you to remove the wiring harness from the motor first and then pull the harness out with the control board.
My wrench was too big to get to the bolt to remove the harness from the motor.
All I did was cut the harness - since they supply a new one - then pull out the control board, then pull out the motor.
As far as getting the pulley off, slip it on and off at the large wheel, this is much easier than taking it off at the small motor drive shaft.
The only other thing of note is to make sure you look at the diagram for the conectors a few times before you snap it together.
There are a few ways you could hook it up wrong so pay attention. There should be no loose ends when you finish.
Also, I couldn't get the flange back on on the rear acess panel when closing it up, but it doesnt seem to serve muc purpose besides asthetics, so I tossed it.

The $200 for the parts and shipping was well worth it. I saved about $150-250 to do it myself...."

Maytag Neptune front loader, model # MAH5500BWW had a digital error code reading Lr. Will not agitate or spin out.


the LR code means "Locked Rotor". when this happens the cause is one of two items. 1) the circuit boardat the top of the unit has lost connection to the motor and its controlboard at the bottom (connector loose) or 2) the motor and or controlboard at the bottom have trashed and need to be replaced (P/N12002039).
Hope that helps,
Thanks,
Lee

What is Lr code mean.


The LR code means "Locked Rotor". This could be due to:
  1. The control board at the top of the unit has lost connection to the motor and its control board at the bottom. Check for loose connectors. Also try 're-seating' each connector by pulling it off and pushing it on two or three times.
  2. The motor and/or control board at the bottom are shot.

What does error code Lr mean


The LR code means "locked rotor" which is just a way of saying the control is not seeing the motor turning. 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. could also possibly be the Water Inlet Valve w/Thermistor #22003834 needs to be replaced due to having Well Water with lots of sand, in the water it is not closing the valve properly allowing water to continue filling the tub, causing it to read the load being too heavy and also leaking out the front door

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


Hi

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.
Thanks

Fills with water then code LR comes up and it does nothing


Hello tombs72,

Unffortunately the LR code means locked rotor. Normally this requires replacing the motor and motor control board (sold together as one unit). I hope this answers your question.

Thanks,

Display error code of Lr on control panel


L means "Lid or Door Lock" problem
r probably means 'release' I couldn't find it anywhere... so I'd guess that Lr means the machine did not detect that the Lid Lock released and cycle end (which means either the sensor is bad or the Lid Lock dosen't lock the Lid).

Either way, something with the Lid Lock system ais not right. Be glad it releases ;-)
