Possible Causes

High room humidity, door gasket leaks, mullion heater (if equipped) not operating, doors opened frequently

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing any heater wiring or controls.

Steps to reduce exterior condensation:

  • Check room conditions: High humidity can cause condensation. Use a dehumidifier or improve ventilation if possible.
  • Inspect door seals: Ensure gaskets are sealing properly to prevent warm, moist air from entering.
  • Mullion heater (if present): Some Danby models have a heater around the door frame. If condensation is heavy around the frame, the heater may not be working. Check for a control setting (energy saver switch) that may disable the heater and adjust as needed.
  • Clean surfaces: Wipe away moisture regularly to prevent mold growth.
