Frost Build-Up in your Fridge and Freezer

What Causes Frost Build-Up?

Frequent Door Opening or Improper Sealing

1. Every time you open the door, warm air enters, condenses, and turns into frost. If the door isn’t sealing properly due to a worn-out gasket, cold air escapes, and frost accumulates.

   Blocked Air Vents

2. The cold air needs to circulate efficiently to maintain proper cooling. If vents are blocked by food items, airflow is restricted, leading to frost formation.

3. Faulty Defrost SystemMost modern freezers have an automatic defrost function. If the defrost heater or thermostat malfunctions, excess frost will start to build up.

   High Humidity Levels

4. Moisture in the air can enter your freezer and condense, creating layers of frost. This is especially common in humid climates.

   Leaving Warm Food Inside

5. Placing hot or warm food inside the fridge or freezer causes excess condensation, which can freeze and turn into frost over time.

How to Prevent Frost Build-Up

• Check the Door Seals

•  Regularly inspect the door gasket for cracks, gaps, or signs of wear. If the seal is loose, replace it to ensure an airtight closure.

• Limit Door Openings

•  Avoid frequently opening the fridge or freezer door, especially in humid conditions.

• Organize Your Storage

•  Keep food items away from the air vents to allow proper circulation of cold air.

• Regularly Defrost the Freezer

•  If your appliance does not have an auto-defrost function, manually defrost it when frost reaches about ¼-inch thick.

• Check for Defrost System Issues

•  If you notice excessive frost despite normal use, you may need professional service to inspect the defrost heater, timer, or thermostat.
