Finding ice buildup in your freezer is never a good sign. Unless you left the door cracked open for an extended time, there is likely a faulty component in your appliance causing the frost to form. Check out the list below to troubleshoot what's causing the frost buildup in your freezer and learn how an appliance repair service can help.

Issues Causing Frost in Your Freezer

1. Unsealed Door

The most common cause behind ice buildup in a freezer is a faulty door seal. If the rubber gasket circumventing your freezer is loose or improperly aligned, the door will not seal correctly when shut. This allows outdoor air to reach the chilled interior of the appliance, causing humidity to freeze and leave ice in its wake. A defective gasket is a minor issue and an appliance repair professional can easily realign or replace this freezer part.

2. Malfunctioning Defrost Timer

The defrost timer is a freezer component built to keep frost from forming on the evaporator coils. This timer is supposed to operate at intervals throughout the day. However, if the timer becomes defective, the cycle will not proceed as scheduled, and ice will build up. To resolve this issue, you'll need to replace the broken component with a working timer. 

3. Faulty Defrost Thermostat

Another possible culprit behind the frost buildup could be the defrost thermostat. This thermostat tracks the evaporator coils' temperature and controls when defrosting functions power on and off. If the thermostat is not accurately reading temperature or communicating correctly with the rest of your appliance, its defrosting capabilities will not work correctly. A professional in appliance repair can diagnose the issue with your thermostat and order replacement pieces accordingly.
