Safety first: Disconnect power and let the appliance cool fully.

Check for moisture: Remove the inner pot and inspect the heating plate area. If there are food spills or moisture around the sensor, clean and dry thoroughly. Allow several hours to dry before retesting.
Inspect sensor wiring: Remove the bottom cover. Look for pinched, melted, or bare wires from the NTC to the PCB. Repair or replace damaged wiring with heat‑resistant cable.
Measure resistance: Use a multimeter to measure the NTC at room temperature. If the reading is very low (e.g., <1 kΩ) or near 0 Ω, the sensor is shorted and must be replaced.
Check for board damage: Inspect the area around the NTC input on the control board for burn marks or corrosion. If present, the main PCB may need replacement.
Reassemble and test: After replacing the sensor or repairing wiring, reassemble and run a test program with water.

Warning: Never operate the cooker with exposed or taped‑together sensor leads; use proper connectors and heat‑resistant parts.
