Frigidaire Refrigerator: not defrosting
What is this symptom?
Is your Frigidaire refrigerator not defrosting? If the freezer is accumulating frost and ice on the evaporator coils, it may be failing to enter its defrost cycle. This issue can lead to inefficient cooling and potential spoilage of food. Understanding the common causes and solutions can help restore your appliance's performance.
Important Tips for Frigidaire Models
- Frigidaire defrost systems use a defrost control board and sensor fuse; blown sensor fuse stops defrost until replaced.
Possible Causes
Defrost heater failure
How to Identify: Evaporator coils remain covered in ice and heater shows no continuity on multimeter test.
Part: Defrost heater assembly
Defrost thermostat/thermistor failure
How to Identify: Thermostat doesn’t close at low temperature; continuity test fails; defrost cycle not triggered.
Part: Defrost thermostat or sensor
Defrost control board or timer malfunction
How to Identify: Timer doesn’t advance; control board doesn’t send power to defrost components; no periodic defrost cycles.
Part: Defrost control board or defrost timer
DIY Solutions
Test and Replace Defrost Heater
- Unplug refrigerator and access the evaporator area by removing freezer rear panel.
- Use multimeter to check continuity of defrost heater.
- If no continuity, order replacement heater for model and install new heater.
- Reassemble panels and restore power.
Test and Replace Defrost Thermostat/Sensor
- Unplug refrigerator and access thermostat near evaporator.
