Here's a comprehensive guide to freezer frost build-up issues:
Common Causes
1. Door Seal (Gasket) Problems
- Signs: Damaged or loose door seals letting warm air enter
- How to check: Insert a dollar bill between seal and frame - if it slides easily, the seal needs attention
- Solution: Clean the gasket with warm water and mild soap, or replace if damaged
2. Door Opening Habits
- Problem: Opening the door too frequently or keeping it open too long allows moisture to enter
- Solution: Minimize door opening time and frequency
3. Overpacking Issues
- Problem: Too many items blocking air vents prevent proper circulation
- Solution: Ensure proper spacing between items and keep vents clear
4. Temperature Settings
- Problem: Incorrect temperature settings can cause excess frost
- How to check: Use a thermometer to verify settings
- Recommended settings: Keep freezer at 0°F (-18°C)
DIY Solutions
- Turn off the freezer
- Remove all food items
- Place towels around the base
- Leave doors open and wait for frost to melt
- Never use sharp objects to scrape frost
When to Call a Professional
Contact a repair service if:
- Frost returns quickly after defrosting

⚠️ Never use electrical appliances inside the freezer or sharp objects to remove frost as these can damage the unit.
