Stewart for Model Number MAH5500BWW Getting the Lr error code. went through the diagnostics. have 120Vac going into motor control board. when i run the spin test the motor starts and spins but it's erratic. took off motor harness hooked meter to blk and grey wires. started spin test and noticed the voltage spiking. then put back harness on motor and kept tester on harness, motor ran erratic and same voltage fluctuation. Now it looks like i can purchase the repair kit on this page or buy the motor control board by it's self. $250 for kit $190 for board alone. for $60 more dollars i get a new motor. what should i do. also my washers motor is still on warrranty for one more year.
Answer Stewart, Your motor tach circuit/ data link is the JP4 harness on the motor control board and is attaches to the P2 connector on the machine control board. Check for 12 to 20 VDC across the blue and yellow wires on the P2 connector. In agitate, the VDC will fluctuate 0 to 5 VDC. On spin The voltage will fluctuate up to 20 VDC and will drop and "settle " around 12 VDC when the tub reaches a full spin speed. Also depending on your series number(first two digits of the serial number), you may have to order the individual parts, and the motor control board would be the most likely issue, in that case.
