After replacing the bearings in my Maytag Neptune MAH4000AWW
, I could not get the unit to spin up. I jumped the three switches on the wax motor/door assembly, to eliminate this from being a possibility (in other words, the door lock light is on without the door even on the unit !).
After several hours of head scratching, and refusing to just buy parts until it worked, I determined that the problem had to be with something I had taken off. The machine did work prior to the bearing replacement; it just howled like a jet.
Upon checking all the wires, I found that the 3 pin connector (white, blue, black wires) on the motor had loosened from it's printed circuit board (assembly part # B02323802B000). The part is available for about $50, but I think I'll just solder it back on. This is the tachometer unit on the motor.
Also, I'll replace the wax motor with the new "black shaft" (# 12002535
), about $12.10, and install a 500ma quick blow fuse in the Brown14 wire from the wax motor to the main circuit board, connection P7, pin 4.
I have not blown the famous R11 resistor yet. I intend to replace all four transistor that are known to fail.
