You have a locked rotor and need a need motor and motor control
maytag used to sell these replacements as a kit
but you may be able to get away with just a motor control

Frequent LR code, need complete troubleshooting proc. advanced


LR code is usually caused my the motor and motor control board. if you have 120v to the motor control board and remove the multi pin connector and see if the motor goes in to a 50rpm spin. But more than likely it is those 2 parts. If the tub is noisy or hard to turn in spin motion it may be a bad rear bearing putting strain on the motor also.

Error codeLr?


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.

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.

Motor won't engage. Error code LR comes up, but the drum, belt, and pin coming out of motor spins freely. May I get possible ideas for troubleshooting PLZ ?


code LR is a Locked Rotor on the motor,but you say the motor runs,then you need to open the top cover by removing the screws inside the detergent cover after unplugging the unit,inside ther should be a tech diagnosis sheet to help you diagnose your problem,just from this its either a bad tach sensor or pick-up coil on the motor that senses the motor speed during all washing cycles,if this sensor is bad it will show up as if the motor isn;t running or a LR code

Code lr ?


hate to interject
but lr stands for locked rotor
your motor control has blown a fuse or heat sync.
you can verify this by removing the door and front panel,
the motor control is on the bottom right front
inspect this board with a flashlight

im almost sure you will find some sort of burning
if you do and would like to repair the unit im including a link
that will show you the part you will need

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.

From another source..."Installing replacement motor, motor control harness, and motor control circut board.

Pretty easy install. On a scale of 1 to 10 (ten being hardest) 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...."
