How to Force Frigidaire Freezers Into Auto Defrost Mode

The defrost cycle on a Frigidaire freezer is typically set or started with the thermostat that is controlled or set by an electronic or mechanical timer. Newer Frigidaire refrigerator/freezers have a temperature control that you can use to manually force the defrost cycle or auto defrost mode.

Electronic Timer

Fridigaire refrigerators/freezers can be forced into auto-defrost mode.
  • Open the door to the refrigerator or freezer section, depending on the type of unit you have.

  • Find the freezer control knob that is used to set the temperature for the freezer section.

  • Set or turn the freezer control knob to "0" or zero. This will manually turn off the compressor and prevent the freezer from cooling.

  • Find the "On/Off" button if you have a control panel on your Frigidaire freezer. Hold the button for three seconds to turn off the cooling system. Press and hold the "On/Off" button for an additional three seconds to turn the cooling system back on.

  • Mechanical Timer

  • Open the door to the freezer section or compartment.

  • Find the timer for the thermostat and locate the advancing screw.

  • Place the end of a flathead screwdriver into the head of the advancing screw.

  • Turn the screw clockwise slowly until you hear a click sound. The click indicates that the timer has activated the defrost mode for the freezer.
