Customer Questions and Answers for Timer (Invensys Hd) by Whirlpool

This mechanical timer controls cycle selection and advancement on compatible dryers. It sequences the motor and heater through the chosen program so the machine runs for the correct duration and shuts off at the end.

• Advances the cycle by opening/closing internal contacts to power the motor and heater
• Restores proper timing when the original timer motor is seized or contacts are worn
• Helps resolve: cycle won't advance, runs too long or stops early, only some settings work, timer doesn't move on its own
• Maintains predictable cycle lengths and proper end-of-cycle shutoff

• Disconnect power; turn off gas supply for gas models
• Access the timer behind the control panel; photograph wiring and transfer leads one at a time to matching terminals
• Mount securely to the original locations; align the shaft with the control knob
• Reassemble and run a short test cycle to ensure the timer advances properly
