Frost or ice buildup on the interior walls and ceiling of the RCA freezer.

Safety first: Unplug the freezer before defrosting heavy frost. Use towels to absorb water.

Steps to reduce frost:

• 1. Inspect door gasket: Look for cracks, tears, or hardened sections. Close the door on a strip of paper at several points; if it pulls out easily, the seal is weak.
• 2. Replace gasket if needed: Remove the old gasket by loosening the retaining screws or pulling it from the channel. Install an RCA-compatible gasket, pressing it evenly into place and tightening screws gradually.
• 3. Check door alignment: Ensure the door is square and level. Adjust hinges if the door is sagging.
• 4. Limit door openings: Organize contents to minimize open time. Avoid leaving the door open while loading/unloading.
• 5. Verify door switch: Make sure the evaporator fan stops when the door is open. If it continues running, replace the door switch to prevent drawing moist air in.
• 6. Manual defrost: Defrost the freezer completely before restarting to remove existing frost.

Tip: A tight door seal is the most important factor in preventing frost buildup.
