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.
