My MAH5500BWW washer started giving the Locked Rotor error.
I’ve been fixing my own Neptune’s for about 13 years and I need some help on this one.
I have the main manual and the one for the 5500B.
The washer fills fine and then the door locks and the tub spins one way for a few seconds then reverses for a few seconds and then never turns again for the rest of the timer cycle. The pump runs continually at the end of the cycle and never turns off. The motor control board is the new type without a fuse. There are no burnt components that I can see. I checked the triacs for shorts and found all of them checked similar. The motor windings are not separate coils. They are tied together on one leg. I tested and got about 7 or 8 ohms between any two of the leads. When I run the SPIN CYCLE TEST in the service mode, it completes all of the steps right up to 1000 rpms with no problems, but if I run the cycle check, the everything happens except the tub will not rotate at all. The bearings are fine, the pump works fine, the door lock works fine.
Any help is greatly appreciated.
Happy New Year
