How to Fix / Troubleshooting
Safety: Unplug the unit before inspection.
Steps to address E7:
- Power reset: Unplug for 10 minutes and retry.
- Locate ambient sensor: This sensor is usually near the air intake grille or mounted on the control panel area, connected by a small harness.
- Inspect sensor and harness: Ensure the sensor capsule is intact and the harness is not pinched or cut. Reseat the connector on the main PCB.
- Clean dust: If the sensor is covered in dust, gently clean it with a dry brush or compressed air.
- Replace sensor: If E7 persists, replace the Homedics ambient temperature sensor with a compatible part for your model.
- Board replacement: Continued E7 after sensor replacement indicates a defective control board that should be replaced by a professional.
