How to remove frost buildup from your freeze

Is there frost buildup in your freezer? If so, you should tackle this issue right away, as it means your appliance is consuming more energy than it should. At Ateliers G. Paquette, we offer expert home appliance repair in Quebec as well as a vast inventory of spare parts. With our years of experience in freezer repair and maintenance, we know how to get rid of frost buildup in a quick, safe and eco-friendly fashion. In this article, we tell you how to defrost your freezer in just six simple steps.

However, first note that modern freezers come standard with an auto-defrost system. This mechanism includes an electronic or mechanical defrost timer, a heater circuit and a defrost limiter thermostat. When one of these components stops working, frost is in the forecast. In such circumstances, you’ll need to call in a technician to repair or replace the part. However, before you do, perform a few checks to verify that your auto-defrost system is actually on the fritz: sometimes an ice buildup can be caused by a cracked gasket or a defective door that won’t close properly.


How to defrost your freezer

Need to defrost your freezer the old-fashioned way? Just follow these six simple steps:


  1. Store the contents of your freezer in a cooler containing ice packs or ice.
  2. Unplug the unit or put it in sleep mode.
  3. Spray hot water on the frosty surfaces (or pass a water-soaked sponge over them).
  4. Use a wooden spatula to peel off the ice (if that doesn’t do the trick, try an unsharpened scraper).
  5. Carefully wipe down the racks and walls.
  6. Clean and deodorize surfaces and seals with a non-toxic cleaning solution, such as mix of water, white vinegar and lemon juice.


If there’s a lot of frost, you can also try placing a container of boiling water in your freezer (on a trivet): close the door and let the steam melt the ice (this should take about 15 minutes).


Defrosting a freezer is a straightforward task. If it’s several years old, you may need to defrost it every three to six months, depending on the way you use it and its placement.
