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...."

I have a Maytag Neptune Washer Model #MAH5500BWW. I am getting an Lr error code. I ran a diagnostic wash and it stopped with the Lr cade and I pushed ^ t continue the diagnostic test. What should my...


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.

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

Lr code on waher display panel,what does it mean?


Hi, Lr is the error for a locked rotor. The machine is trying to run the motor but is unable. Usually this the motor control board that is at fault. The first thing to do is make sure the belt is on. After that some tests are have to be made to determine what is going on. Im going to lay out some instructions in case you want to get into this thing. You will have to remove the door by removing the screws holding the hinges on. Same thing for the spacers on the other side. Lift up and remove the door. Pull the front panel forward and lift off. Once the panel is off, set the door back on and close it. Unplug the washer. On the motor control board, bottom right, pull the JP4 harness connector from the board. Plug the washer back in and make sure the door is closed. Press delicates and heavy soil 3 seconds to activate the service mode. Now press the rinse key. Make sure the door is locked by pressing the max extract key. Now press the stain cycle to start motor control test. The motor should run rotating the drum at 50rpms. If the motor doesn't run, check for voltage at the 3 wire harness, MN4, should be 120V. If you don't have the voltage, problem is in the main board. If you have that voltage, then the problem lies either in the motor control, or motor itslelf. On the motor harness, 7 pin connector on the board (middle). Between the brown, white and black wires should all read 6 to 7.5 ohms. Between the 2 grays 150 to 195 ohms. If that checks, then it's the board. If it doesn't check, it's the motor. Ohm checks should be done with the power off.

Take care

I am doing a load of laundry the washing machine maytag neptune


This means locked rotor. you have a bad motor control unit. take the door off by removing the 4 screws also take the side/front panel off. You will see the motor control board. Do you have a delay wash cycle? If you do set it to delay wash remove the jp4 connector if the unit tumbles on it's own then the motor controller is fine but if it does not then you have a bad motor control board. Check it out and let me know. also there is a fuse on that board if you can locate it and check for continuity that will also help diagnose it. MAKE SURE YOU UNPLUG IT FIRST THOUGH!!!!

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 ;-)

MAH5500B washer won' spin. LR appears on display.


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.
