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.

I have a Maytag front load Neptune MAH5500BWW problem

Q: Hi. I have the MAH5500B washing machine. My wife called in a panic and said the LCD panel displayed the LR code. I read 120V ac at the receptacle. I read 120V ac at terminals 1 and 3 on connector P6 at the machine control panel. I ran the Quick Service Cycle and everything seems to function except the tub does not spin. Checking across the 10 amp fuse on the motor control board yields 1 ohm resistance. I am thinking motor but I am not sure...any ideas? 

 A: Sure. You will have to replace the Motor control board and the motor with the new Maytag 12002039 motor conversion kit which may be available on ebay https://ebay.us/Aac7zW. If you already have the newer motor control board with plastic cover, you can try just replacing your motor control board. You can look at the photos on ebay and see if they look like your motor control board.

 

It takes about an hour to install. The original motor control boards have a high failure rate on the Neptunes so Maytag decided to redesign both the motor and motor control board. 

 Have you noticed your Neptune getting loud in spin cycle? If so, then your bearings are failing and will need to be replaced. The extra friction caused by the failing bearings can cause the motor control board to shutdown and/or fail. You can get new bearings and seal kit from www.neptunebearing.com. They also rent the special Neptune bearing tool to save you lots of time and effort and the rental incudes access to a video that shows you how to teardown machine, replace bearings using tool and install the seal kit. If you ask a service technician to come over you will receive a dose of sticker shock! They will quote you over $900 to quiet your machine again...

Until next time...
