Condensation or water droplets forming on the inside of the glass door.

Safety: No internal electrical work is required for basic checks, but unplug the unit if adjusting hinges or replacing gaskets.

Steps to reduce door condensation:

• Check door seal: Inspect the gasket around the door for gaps, tears, or hardened sections. Close the door on a strip of paper at several points; if it pulls out easily, the seal is weak.
• Adjust door alignment: Tighten or adjust hinges so the door closes squarely against the cabinet.
• Clean gasket: Wipe the gasket and mating surface with warm soapy water to remove dirt that may prevent sealing.
• Replace gasket if needed: Install a Haier-compatible door gasket if the original is damaged or permanently deformed.
• Control humidity: If the room is very humid, consider using a dehumidifier or relocating the cooler to a drier area.
