Frost Blocking Your Evaporator Coils? A Failed Defrost Timer Is the Most Common Cause.

When the defrost timer fails, the automatic defrost cycle stops — ice accumulates on the evaporator coils, airflow is blocked, and the refrigerator loses its ability to cool. The 102397-1 is the OEM replacement defrost timer for Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Tappan, and Westinghouse top-mount and bottom-mount refrigerators.

Symptoms of a Failed Defrost Timer

• Frost or ice buildup on the back wall of the freezer compartment
• Refrigerator not cooling properly despite the freezer feeling cold
• Refrigerator never enters defrost cycle — or runs defrost continuously
• Evaporator coils completely iced over
• Fan running but no cold air circulating into the fridge section
