How to Fix / Troubleshooting
Safety first: Unplug the cooker and ensure it is cool.
- Inspect recent repairs: If the unit was recently serviced, check that all sensor connectors are correctly placed and not swapped.
- Check cable routing: Open the housing and look for sensor cables pinched by screws or plastic clips. Reroute as needed.
- Look for moisture: Dry any condensation or spills around connectors and sensors.
- Continuity test: Use a multimeter to check for shorts between sensor wires and chassis. Replace any damaged harness.
- Replace sensor/harness: If the short cannot be cleared, replace the affected sensor and wiring harness with Hisense-compatible parts.
