Why Does My Freezer Keep Freezing Up?

Imagine on one fine day, you reach into your freezer for a bag of frozen peas, only to find it encased in a thick layer of ice. Frustrating, right? Not only is it a hassle to chisel your food out of an icy tomb, but a freezer that keeps freezing up can also lead to spoiled food, higher energy bills, and even potential damage to your appliance.

Don’t worry, these things happen! Freezer freezing up is a common problem, but it can be solved.

In this post, we’ll break down the most common culprits behind a frosty freezer and provide practical solutions to keep your food frozen and your freezer functioning at its best.

Common Causes of Freezer Freezing Up

So, what’s causing your freezer to resemble the Arctic? Here are the usual suspects.

Door Issues

Your freezer door is designed to keep warm air out and cold air in. But warm, humid air can sneak in if the door seal (that rubber gasket around the edge) is worn out, cracked, or not sealing properly. This moisture then freezes inside your freezer, creating that annoying frost buildup. 

Look for signs of trouble, like visible damage to the seal, gaps, or frost forming around the edges of the door.

Temperature Settings

Believe it or not, setting your freezer too cold can cause it to freeze up. When the temperature is excessively low, the compressor (the heart of your freezer) runs less often. This can lead to warmer air inside the freezer, which in turn causes moisture to condense and freeze. The ideal freezer temperature is between 0°F and -10°F (-18°C and -23°C).

Defrost System Malfunction

Most modern freezers have a defrost system that periodically melts any frost that builds up. This system typically consists of a defrost heater, a defrost timer or thermostat, and a drain pan to collect the melted water. If any of these components malfunction, the frost won’t melt, and your freezer will start to resemble a winter wonderland.


We all love stocking up on frozen goodies, but overpacking your freezer can cause it to freeze. When the freezer is crammed full, airflow is restricted, and the appliance has to work harder to maintain the proper temperature. This can lead to warmer spots where moisture can condense and freeze. So, resist the urge to hoard frozen pizzas and leave some breathing room for your freezer!

DIY Troubleshooting Tips

Ready to tackle that freezer frost yourself? Follow these simple steps:

Check the Door Seal

  1. Inspect: Closely examine the rubber gasket around the freezer door for any cracks, tears, or gaps.
  2. The Dollar Bill Test: Close a dollar bill in the door and try to pull it out. If it slides out easily, the seal may be compromised.
  3. Clean: Wipe the seal with a damp cloth and mild detergent to remove debris.
  4. Ensure Proper Closure: Make sure the door closes completely and latches securely. Adjust the hinges or replace the seal if necessary.

Adjust the Temperature

  1. Locate the Thermostat: Usually, it’s inside the freezer or on the control panel.
  2. Check the Setting: The ideal freezer temperature is between 0°F and -10°F (-18°C and -23°C).
  3. Adjust if Needed: If the temperature is outside this range, use the thermostat controls to adjust it accordingly.

Defrost the Freezer (Manual Defrost Models)

  1. Safety First: Unplug the freezer and remove all food.
  2. Remove Ice Trays and Shelves: If possible, take out removable components to speed up defrosting.
  3. Place Towels: Line the bottom of the freezer with towels to absorb the melting water.
  4. Wait it Out: Let the ice melt naturally. To expedite the defrosting process, try placing bowls of hot water inside the freezer or using a fan to increase air circulation.
  5. Clean and Dry: Once the ice has melted, clean the interior thoroughly and dry it completely.
  6. Reconnect and Restart: Plug the freezer back in and return the food.

Tip: Never use sharp objects to chip away ice, which could damage the freezer’s interior. If your freezer has an automatic defrost function and is still freezing up, professional help may be needed.
