Machine starts normally with the water fill then starts to tumble. after a minute or so of tumbling I get an "LR" error code but the motor is still running. Also I have ~150 volts at the Motor Control Board Input on the black wire. This should be 120 volts. I have replaced the motor control board with a 22004046 which is supposed to be compatible. This 150 volts is coming from the Machine Control Board at the top of the machine. I have checked everything I that can be checked (I think) and am now thinking the Machine Control Board is the problem.

Ron for Model Number MAH5500BWQ

ANSWER Hello Ron, The first thing you want to do is check your serial number to ensure that you have the right board installed into unit. The first 2 digits will tell you what control you need. If the first two digits are below 88 then you need the motor control kit 12002039. If your serial starts with 88 to B8 then you need the 22004046. If the serial starts with C1 then you need part 22004473. As far as the voltage, you should only get 120 vac at the white to gray. Gray wire may look black.
