This mechanical timer is the cycle control that sequences your appliance through each programmed stage. Replacing a worn timer restores proper cycle advancement, reliable start/stop, and consistent power delivery to components.

  • Rotates an internal cam with a synchronous motor to open and close contacts in order
  • Directs power to key components at the correct times during the cycle
  • Common symptoms: cycle won't advance or stalls, runs endlessly, won't start unless the knob is moved, erratic timing
  • Timer motor or internal contacts can fail from wear, heat, or arcing; replacement restores normal operation
What's included: 1 timer assembly Install notes:
  • Disconnect power before servicing; shut off water supply if applicable
  • Label/photograph wiring and transfer leads one at a time to matching terminals
  • Move any brackets/insulators from the old timer to the new unit; reuse your knob and dial
  • After mounting, align the shaft so the pointer indexes "Off" correctly and test cycle advancement
