Question about Maytag Neptune MAH5500B Front Load Washer

1 Answer

Maytag Neptune Washer says "Lr" on LED screen.

It means Locked Rotor, but what parts do I need to fix this? Can I do it if I have the parts or do I need a service tech?

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" 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.

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 (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...."

I have Maytag Neptune front loader washer. When


Hi.

Error LR means Locked Rotor.

Either the motor is faulty, there is a wiring problem, or the control assembly is faulty.

Try tripping the circuit breaker to reset the machine, if code comes back a technician must have a look at the motor.

See this post for troubleshooting the Lr error code. . http://www.fixya.com/support/t2419091-maytag_neptune_top_load_fav6800aww_tub

Lr is locked rotor. My first thought was that this could be a Motor Controller issue. This owner replaced tried that and it did not resolve the issue. He then replaced the main Control Board and that fixed his machine. Without known good parts (Control Board Motor Controller) this might be difficult for a DIY fix.

What does error code Lr mean and how do I fix it?


http://www.bobvila.com/wwwboard/messages/155863.html

says:

just an FYI to anyone who might need to know. my neptune started kicking up an error of LR and stopping. i ended up sending an email to maytag and got a response back from one of their techs. the LR code means "Locked Rotor". when this happens the cause is one of two items. 1) the circuit board at the top of the unit has lost connection to the motor and its control board at the bottom (connector loose) or 2) the motor and or control board at the bottom have trashed and need to be replaced (P/N 12002039).

hope the info helps someone as i had a heck of a time finding it.
