Unit makes loud clicking, popping, or buzzing noises while heating.

Safety first: Unplug the cooker before opening the base. Occasional soft clicks can be normal; loud or irregular noises may indicate a fault.

• 1. Identify noise type: Soft periodic clicks are usually normal relay operation. Loud pops, crackling, or buzzing are not normal.
• 2. Inspect heater terminals: Remove the bottom cover and check heater connections for looseness or burn marks. Tighten or replace burned connectors.
• 3. Check mounting screws: Ensure the heating plate and internal brackets are firmly secured to reduce vibration.
• 4. Observe operation (advanced): With extreme caution and the base reattached, run the unit and listen near the control board. Continuous buzzing from the relay area suggests a failing relay, requiring board replacement.
