By: Frigidaire
Part Number: OEM20399667
Manufacturer Part Number: 5304518034

The Defrost Timer is an OEM replacement part for Frigidaire upright freezers. It serves as a crucial component responsible for regulating automatic defrost cycles.

Causes of a faulty defrost timer relate to 20,000+ hours of constant exposure to freezer temperatures as low as -10 degrees Fahrenheit. Such extremes can compromise electrical switching mechanisms over prolonged usage periods.

Symptoms of a failed defrost timer include:

  • Inability to initiate automatic defrost modes  
  • Excessive ice and frost accumulation inside cabinet
  • Warm areas detected due to impaired fan circulation
  • Diagnostic codes indicating defrosting problems

This genuine Frigidaire replacement part is compatible with Kelvinator and some Kenmore units as well.
