Safety first: Unplug the cooker before handling internal wiring.

Wiggle test (advanced): With the base open and the unit unplugged, gently move the sensor wires and connectors to identify any loose or intermittent connections.
Clean connectors: Use contact cleaner on sensor plugs and reseat them firmly.
Secure wiring: Use cable ties to prevent wires from moving excessively during use.
Replace harness: If moving the harness affects the fault, replace the sensor wiring harness.
