Display shows E10 and the interior humidity is abnormally high or low, affecting cork condition.

Safety: Disconnect power before accessing control panels or sensor wiring.

• Confirm model features: Not all Blastcool wine coolers have active humidity control. If yours does, it will typically have a humidity display or setting.
• Locate humidity sensor: The sensor is often mounted on the interior side wall or behind a small grill near the middle of the cabinet.
• Visual inspection: Check for condensation, mold, or physical damage on the sensor. Gently clean with a dry cloth; do not soak or spray cleaners directly on it.
• Check wiring: Trace the sensor cable to the main PCB and ensure the connector is secure and free of corrosion.
• Replace sensor if faulty: If the humidity reading is clearly unrealistic (e.g., 0% or 99% constantly) and wiring is intact, install a new Blastcool humidity sensor module.
• Verify cabinet sealing: Inspect the door gasket and cabinet joints for air leaks that can disrupt humidity control. Replace a damaged Blastcool door gasket if needed.
• Test operation: Restore power and monitor humidity readings over 24 hours with an independent hygrometer inside the cabinet.

If E10 persists with a new sensor and good sealing, the humidity control circuitry on the main PCB may be defective and require professional replacement.
