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

Safety: No electrical work is required for basic checks.

Steps:

• Check door closure: Ensure the door closes fully and latches. Remove any bottles or racks interfering with closure.
• Inspect gasket: Look for gaps, tears, or hardened sections of the rubber gasket. Warm the gasket gently with a hair dryer (on low) and reshape to improve sealing.
• Level the unit: Make sure the cooler is slightly tilted back so the door closes by itself.
• Ambient humidity: In very humid environments, some condensation is normal. Use a dehumidifier in the room if possible.
• Door replacement: If condensation persists between the glass panes, the door's sealed unit has failed and the glass door assembly should be replaced.
