Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact code

    • Write down which code from F72 through F78 appeared.
    • Confirm the full model number before resetting.

  2. Power cycle once

    • Turn off the dryer circuit breaker for five minutes.
    • Restore power, start a Time Dry cycle, and monitor for one minute as Whirlpool documents.

  3. Preserve a returning code

    • If the code reappears, stop and request service.
    • Do not keep clearing the same code.

Actions not recommended

  • Do not open panels or access internal electrical parts.
  • Do not replace controls based on the code alone.
  • Do not continue using the dryer if a fault returns.

When to stop and request service

  • The code reappears after one documented power cycle.
  • The dryer cannot be powered off safely.
