Customer Questions and Answers for Defrost Timer by Frigidaire

4.89 (64)
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.

You will want to check for possible vibration of the condenser coils on the back of the unit if there are coils. Also check for vibration of refrigerant lines. These would be the most common reasons for the noise. Also check to make sure that there is no ice building up around the fan.
