Timer and clock lose settings or reset randomly; oven may shut off unexpectedly.

Safety first: Disconnect power before tightening electrical connections.

• 1. Check terminal block: Access the rear of the La Cornue oven and inspect the power terminal block. Tighten any loose screws and replace burned connectors.
• 2. Verify supply voltage: Use a multimeter to confirm stable line voltage at the terminal block. If voltage fluctuates significantly, consult an electrician.
• 3. Power reset: Turn off the breaker for 10 minutes to clear the control memory, then reprogram the clock and test.
• 4. Replace control board: If settings continue to reset and power connections are solid, the main control board's memory or power supply section may be failing and should be replaced.
