Oven display shows F10 and the clock or timer cannot be set, preventing the oven from starting.

Safety first: This is primarily an electronic fault; no high-voltage components need to be touched for basic troubleshooting.

• 1. Full power reset: Turn off power at the breaker for at least 10 minutes. Restore power and immediately set the time and date according to the user manual. Many Fisher & Paykel ovens will not operate until the clock is set.
• 2. UI button test: Check that all clock-related buttons (e.g., +, -, Timer, Set) respond and beep when pressed. If some buttons are dead, the touch panel or knob encoder may be faulty.
• 3. Software reset (if available): Some models allow a factory reset via a key combination (refer to the service or user manual). Perform the reset and reconfigure the clock.
• 4. Control board replacement: If the clock cannot be set despite a working UI, the main control board's clock circuit may have failed and will require replacement.

If the oven remains inoperative after a reset and time setting, professional diagnosis of the control electronics is recommended.
