Possible Causes
Defective ice room NTC sensor, Damaged sensor wiring in door or liner, Loose connector at ice maker module, Faulty main control PCB sensor input
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before working in the ice maker area.
Steps:
- Locate ice room sensor: In Etna models with a dedicated ice compartment, the ice room NTC sensor is usually mounted near the ice maker or in the ice storage area behind a small cover.
- Inspect sensor and wiring: Remove the cover and check the sensor for damage, loose mounting, or ice encasement. Follow the wiring harness to its connector and ensure it is firmly seated.
- Defrost if iced over: If the sensor is buried in ice, unplug the unit and allow the ice to melt naturally. Dry the area thoroughly before reassembly.
- Resistance check: Disconnect the sensor and measure resistance with a multimeter. Compare to typical NTC values; open or short readings indicate failure.
- Replace sensor if needed: Install a new Etna ice room NTC sensor if the original is defective. Route wiring as originally installed to avoid pinching.
- Test: Restore power and monitor the display. The E7 code should clear once the control detects valid sensor readings.
