Maytag Appliance Parts 22004473 Motor Control Board - LR error code

Maytag Appliance Parts 22004473 Motor Control Board

If you open up the top section you should discover a document in there that has the wiring diagram and diagnostic tests you can run on your Neptune.
The 'LR' error code means Locked Rotor and usually shows up if the motor drive system is not following what the machine control board (MCB) is instructing it to do. The MCB instructs the motor control board how fast and how which direction to rotate the inner basket. I would also check that the belt is still on the pulleys.
Sometimes the motor control board has simply failed and does not rotate the basket or it could be that the speed sensor on the motor has quit working or has a bad connection. I will check all of the connectors in the machine and clean them by removing the connectors and reinstalling them. The sliding action will clean the connector pins if there is oxidation built up on the pins. Just make sure you install the connectors in the exact same position they were originally. When working around the motor control board which is located near the floor I would take a look at the board and see if there are any physical burnt components, leaking or bulging capacitors, etc.
After inspecting all of the connectors in the machine that you can get to I would retest the motor drive. If it does not rotate the basket and you still get the LR error code it is time to replace the motor control board. In 99% of failures the motor control board fails, not the motor. You can visit www.22004473.com for more information on the replacement motor control boards.

Maytag Neptune Washer Keeps Shutting Off


Maytag Neptune Washer Keeps Shutting Off

Above is a photo of a Maytag Neptune motor control board (MCB) that has failed.

The most common cause of Maytag Neptune Washer Keeps Shutting Off is a motor control board failure. The motor control board (MCB) on the Neptune is situated on the right side near the floor pan. On the stand alone models (non stacker) you can remove the door and front panel and take a look at the MCB. If you start up the machine and it shuts off within a few seconds that usually indicates the MCB has failed.
Since there is high voltage on board (170 VDC) components can actually rupture when they fail. Typically, the ten amp fuse will blow or it may zap a copper trace off of the board. If you inspect your MCB but don't see anything burnt on your MCB I would check the connectors on both the MCB and the machine control board which is located in the upper console section. It can help to unplug each connector and re install it to clean the connector pins/contacts. You should also have a special diagnostic sheet with a wiring diagram and other help information.
If you discover that your Neptunes' MCB has failed you cavisit www.washerbearings.com/parts to order replacement parts other than tub bearings and seal. 
Older Neptune's will need the motor conversion kit which includes a new MCB, motor and wiring harness and this is because Maytag had redesigned the motor drive system due to reliability issues on the older machines.
I hope this helped you. Leave any questions or comments below.

My Maytag Neptune washer is growling at me

My Maytag Neptune washer is growling at me...

If your Maytag Neptune front load washer is growling at you then maybe you are working it too hard…

Or it could be that the motor control board (MCB) is failing.

The Neptune MCB is located on the right side down by the floor on the solid door panel Neptune’s including the 2000 stackers. The MCB generates 3 phase power to drive the motor and if one of the phases fails then the motor will sound like it is growling and it will not produce the full torque required to spin the clothes out.

See http://www.12002039.com/ and/or http://www.22004473.com/ for the two common Neptune MCB assemblies.

The 12002039 kit includes a new motor, wiring harness and the MCB that work together. Maytag provided this new 12002039 design because they were having failures on the original motor drive system and decided to use a different technology. The original motor is not compatible with the new MCB. When the motor drive fails your machine will usually turn off a few seconds after you try to start the washer up and on the digital machines you will get an LR error code.








This picture shows a common failure on the MCB. Another failure is when the 10 amp fuse opens.







You will need your model number and the first 2 digits of your serial number to determine which kit you will need.

Until next time...
