Display works but cooker does not heat in any mode (Saute, Pressure Cook, etc.).

Safety first: Unplug the cooker before inspection.

• Confirm symptom: Start a Saute program with the inner pot in place. If the bottom stays cold after several minutes, the heater is not energizing.
• Internal inspection (advanced): Remove the bottom cover and inspect the heating element connections and thermal cutoff fuse.
• Test heating element: Use a multimeter to measure resistance across the heating element. An open circuit indicates a failed element.
• Check thermal fuse: Test continuity of the thermal cutoff fuse mounted near the heating element. Replace if open, but also investigate cause of overheating.
• Replace faulty parts: Replace the heating element assembly or thermal cutoff fuse as needed. If these test good, the main control board heater driver is likely faulty.
