Possible Causes

Door not sealing properly, Defrost heater failure (if equipped), Defrost sensor not detecting frost, Frequent door openings in humid environment

How to Fix / Troubleshooting

Safety first: Unplug the unit. Do not use sharp tools to remove ice; you can puncture refrigerant lines.

Steps to address frost buildup:

  • 1. Manual defrost: Empty the cooler, unplug it, and leave the door open for 12–24 hours until all ice melts. Use towels to catch water.
  • 2. Check door gasket and alignment: Replace a damaged "door gasket" and adjust hinges or leveling feet to ensure a tight seal.
  • 3. Inspect defrost components: If your STAIGIS model has automatic defrost, test the defrost heater and sensor as described in the defrost fault entry. Replace faulty parts.
  • 4. Avoid frequent long openings: Reduce door open time, especially in humid climates.
