Maytag Neptune Stacker won't spin. Not the "wax motor". |

Thanks. Do you know if they use a "logic" circuit? As in a microprocessor needs to see switch open/switch closed? It would be easier to jumper those switches to rule them in/out. | ||

The wax motor "confirmation" switch is the trigger for full-speed spin, and it also is what terminates fluff-mode after the final spin. Fluff (alternate CW/CCW rotation) continues until the wax motor unlatches. Bypassing that switch (tying the wires together) will cause fluff to continue until the machine is manually stopped. | ||

Non Spinning MT Neptune The little micro-switch near the wax motor turns on the lock light, the MS on the right is the spin enable switch, the round plunger must move all the right and push the button on the spin enable switch the tell the control board that the machine can go into a high speed spin. Often I have had to add a thin plastic shim to get the SE switch to activate.
Other than this common problem other likley faults are a broken wire or connection in the unbalance circuit [ you can bypass this circuit for testing purposes ], after this you may have a fault in the washers main board or the motor board may be bad.
Only good news is All of these items can be reached and fixed without moving this machine.

Wax Motor A sealed chamber filled with a temperature-sensitive wax compound ... has a spring-loaded piston on one end, a small heating device on the other end. The wax expands when heated, slowly driving the piston to operate a valve, dispenser or other such function. The wax contracts when cooled and the spring returns the piston (and the connected function) to its original/neutral position. | ||
