mah5500aww won't spin - not a wax motor problem
« on: August 11, 2012, 02:10:37 PM »
I have a Neptune front loader that won't spin. It acts normal, other than never going into the spin cycle.

I pulled the control board, and the resistor & had already been changed. The door will lock normally.
I pulled the motor control board, and did the diagnostic. The drum spins at 50RPM.

What's the next step, oh gurus of appliances?

Thanks for the help!

Attached to the tub are two out of balance switches and a inertia switch tied together in series. If you lift the top you will see two blue wires going from the front of the tub to the back left corner. There is a disconnect there. You can do a continuity check on the circuit at that point. If there is an open circuit look for a broken wire at one of the switches. The shaking tub seems to be hard on the spade connectors on the switches.

Wow - thanks for the super quick answer.

Sadly, I have continuity on that circuit.

Yes, and the door locks and unlocks just fine. The light comes on as well.

Yikes. Is there a way to test to see if that's what's broken?

If you get 50 rpm during diagnostics, your motor and controller should be okay.  Check the spin enable switch.  It's the microswitch on the right side of the door latch.  It should have continuity when the wax motor is fully extended.  I've also seen where the latch was binding and not allowing the plunger to extend completely. OEM switch 22002162 or generic 28QBP0496

Wow - you guys are great.
It was a corroded connection on one of the micro switches.

You gave me the knowledge of where to look, and what to look for (even though the switch was OK).

Thanks a million. You just helped me make my wife very happy.  O0
