Wine cooler shows E17 and may not cool; compressor and fans may be off while lights and display work.

Safety: Ensure adequate ventilation around the appliance before restarting. Disconnect power before internal inspection.

Steps:

• 1. Check ventilation: Confirm that front or rear vents are not blocked and that installation follows Gaggenau clearance requirements.
• 2. Allow unit to cool: Leave the cooler off with the door slightly open for 30–60 minutes to dissipate heat.
• 3. Power reset: Restore power and see if E17 clears. If it returns quickly, proceed with further checks.
• 4. Inspect overtemperature sensor: Some models use a dedicated safety sensor near the compressor or condenser. Test resistance and replace if out of spec.
• 5. Inspect condenser fan and coils: Ensure the condenser fan runs and coils are clean. Overheating from poor airflow can trigger protection.
• 6. Replace control board if stuck in lockout: If all hardware is normal but the board will not exit protection mode, the control may be defective.

Note: Repeated overtemperature events can damage wine; consider using an external thermometer to verify actual cabinet temperature after repair.
