Customer Questions and Answers for Timer (Mechanical Cycle Control) by Whirlpool

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

• 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
