Oven makes a ticking or clicking sound and cycles on and off frequently; temperature fluctuates.

Safety first: Disconnect power before accessing the control area.

• Determine if normal: Some clicking from relays is normal as the oven maintains temperature. Compare with user manual expectations.
• Secure components: Ensure the control board and relays are firmly mounted and not vibrating against metal panels.
• Check temperature stability: Use an oven thermometer to see if temperature swings are excessive. If so, test the sensor and thermostat.

If clicking is accompanied by large temperature swings, the thermostat or control board may need replacement.
