Frigidaire Refrigerator TSK145PN2W Frost buildup

The Defrost Timer is an OEM part for Frigidaire refrigerators. It is an essential electronic component that controls the automated defrost cycle of the refrigerator. The defrost timer monitors run times and temperatures to determine when to initiate the defrost process. It allows the refrigerator to operate efficiently by preventing excessive ice buildup. This defrost timer is designed to run for 30 minutes every 8 hours. 

Symptoms of a bad defrost timer include: 

• Inability to initiate or maintain the defrost cycle 
• Excessive ice buildup in the freezer compartment
• Erratic temperature fluctuations
• The refrigerator running excessively or displaying other performance issues

Causes of a bad defrost timer can be normal wear and tear over time. Environmental factors like power surges or fluctuations may also impact the electronic timer functionality. 

This OEM Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.

The Defrost Thermostat is an OEM part for Frigidaire refrigerators. It monitors the temperature of the evaporator coils and activates the defrost heater when necessary. This process prevents frost buildup on the coils, ensuring the refrigerator maintains optimal cooling efficiency.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup on the evaporator coils
• Refrigerator not cooling properly
• The defrost cycle not activating
• Increased energy consumption

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.
