Likely Causes
How to Fix It
1
Unplug the refrigerator and remove the freezer rear panel to inspect the evaporator coils for frost buildup
2
If coils are heavily frosted, manually defrost using towels and a hair dryer on low heat
3
Test the defrost heater with a multimeter for continuity; replace if open circuit (no continuity)
4
Test the defrost thermostat for continuity while cold — it should be closed circuit when below its set temperature
5
If both the heater and thermostat test good, the main control board defrost control circuit has likely failed and the board needs replacement
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
