Oven clock and display work, but oven will not start heating until the time is set.

Safety first: No internal work is needed for basic timer settings; follow the user manual.

Step-by-step checks:

• 1. Set the time: After a power cut, many Hotpoint-Ariston ovens require the clock to be set before heating is enabled. Set the correct time.
• 2. Cancel automatic programs: Ensure the timer is in manual mode (often indicated by a hand symbol). Cancel any delayed start or end time.
• 3. Test heating: Select a simple manual cooking mode and temperature. If still no heat, the timer relay contacts may be faulty and the clock/timer module may need replacement.
