Neptune Washer Burnt Resistor Tips

Tips that show what components need to be checked/replaced if a certain resistor on machine control board is bad. It is as follows: Burnt resistors in Maytag Neptune washer models MAH4000 and MLE/MLG2000.

The machine control board (MachCntrlBd) resistor circuitry is protected by triacs, which during periods of high current may fail to protect these resistors. Maytag has identified seven resistors that relate to specific components that need to be checked or replaced. Listed here is the resistor ID, the circuit involved, and the recommendation:

  • R9 / pressure switch / check for loose connections or high resistance on switch contacts; replace pressure switch if necessary
  • R11 / door lock wax motor / replace door lock mechanism and machine control board
  • R51 / hot water valve solenoid / replace water valve and machine control board
  • R52 / timer motor / check for loose relay terminal connections and replace machine control board
  • R53 / cold water valve solenoid / replace water valve and machine control board
  • R143 / (-) 24 VDC / contact was made between neutral and the 24 VDC circuit
  • R162 / electrical buffer circuit / wire harness and machine control board
