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...."

May tag washer has error code LR at the 6 minutes left on the cycle. is it worth trying to diagnos and fix


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 if the issue is resolved else post a comment for further assistance.


Thanks

Maytag washer top load neptune


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.

If you are going to try to DIY the repair I will see if I can help……Rich

Error code Lr


LR usually means that the the signal from the control circuit board is not getting to the motor either because of a bad connection at either the motor or the board or the motor itself is no good. Need to check the connections first, if they are ok replace the CCU (central control unit) board, this is the board behind the touch controls.

What is Lr error code


I’ll post this in reference to Troubleshooting an Lr error code associated to the FAV6800AW/FAV9800AW.

Lr = Locked Rotor error “”Locked Rotor: The machine has repeatedly tried to turn the motor””. This could be caused by faulty Motor Controller, Motor, Control Board or issues in communication of the Control Board to the Motor Controller/Motor via the wiring harness. Here are a couple of links to support troubleshooting efforts; Service Manual for reference. Sears Parts Direct for parts reference.

I’m an owner like you and I worked vai e-mail a while back with an owner that was experiencing a constant “Lr” error code on their FAV6800AW. That person ended up replacing the Motor Controller after replacing the motor that did not fix the issue. You could try the Motor Control Board Output Test on page 15 and others checks on page 16 of the SM.
Unfortunately the SM gives very little support in troubleshooting this issue. If you decide to troubleshoot first pull the plug on the 120VAC to the machine. You could try reseating the plug on the motor and the plugs going into the Motor Controller. This could be a hard one to troubleshoot without a known good Motor Controller, Motor and Control Board to substitute. If you are a DIY’er and have an DVM you could try the troubleshooting steps on page 15&16 of the SM.
If it were my issue and the SM troubleshooting steps did not help fault isolate the failed component I would pick up a Motor Controller from ebay (90 day warranty type) and try that first with my fingers crossed, not the way I like to troubleshoot. The Motor and Control Board are under warranty by Maytag for 5 years from DOP. I believe the Motor Control Board is under warranty for only 2 years. Maytag Customer Service contact info is at the back of the SM. Good Luck.

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.

Wont work, flashes LR


rapoyner The "LR" error code means "locked rotor". It appears on the display after the machine has repeatedly tried to turn the motor. The cause of the problem could be the motor itself, the motor control board, the main control board or the wiring. If your washer is less then five years old most likely the parts are still under Maytag warranty. It has very sophisticated design and I wood recommend to call the Maytag authorized repair man even if the warranty is already expired. Gendos
