Answer to continue safely
Is it safe to keep using?
Maybe. The refrigerator may still cool adequately for a short time after a manual defrost, but frost will rebuild and block airflow again within days if the underlying defrost component has failed.
Can I reset the code?
Yes. A manual defrost and power cycle will clear the code, but it will return within one to two defrost cycles (24 to 48 hours) if a defrost component is faulty.
When to stop immediately?
Stop if you notice: Stop if the frost returns to the same thickness within 48 hours of a complete manual defrost., Stop if water continues to leak onto the floor after clearing the defrost drain..
Symptoms You May Notice
Heavy frost on freezer rear wall
A thick layer of ice or frost covers the inside rear wall of the freezer compartment and the evaporator coils behind it.
Refrigerator section warming up
The fresh food compartment temperature rises because ice-covered coils block the airflow vents between the freezer and refrigerator.
Compressor running continuously
The compressor runs for extended periods without cycling off as it struggles to reach target temperatures through frost-blocked coils.
Water leaking onto floor
Partial or uneven melting during failed defrost attempts causes water to overflow the drain pan and leak onto the kitchen floor.
Possible Causes
Defrost heater element burned out
The glass-tube or calrod defrost heater has an open circuit and no longer produces heat when energized by the control board.
Requires ProfessionalDefrost thermostat (bi-metal) failed
The defrost thermostat is stuck open and will not close to allow current to flow to the defrost heater.
Requires ProfessionalDefrost drain line frozen
The defrost drain tube is blocked with ice, causing water to refreeze on the coils and making defrost cycles appear to fail.
DIY PossibleSafe Checks You Can Do
-
1
Manual defrost the freezer
Unplug the refrigerator, remove all food from the freezer, open the doors, and place towels on the floor. Allow eight hours for all ice to melt completely.
Place a fan blowing into the freezer to speed up the defrost process to approximately four hours.
-
2
Clear the defrost drain
Locate the defrost drain hole at the bottom rear of the freezer compartment and pour a cup of warm water into it to ensure it drains freely.
Use a turkey baster to direct warm water precisely into the small drain opening.
-
3
Monitor after restart
Plug the refrigerator back in and check the freezer rear wall for frost buildup after 24 and 48 hours to determine if the defrost cycle is working.
Mark the frost line with a piece of tape to easily see if frost is accumulating beyond that point.
When to Call a Professional
Contact a qualified technician if:
- Frost rebuilds to full thickness within 48 hours of manual defrost, confirming a defrost component failure requiring repair from $150.
- A continuity test on the defrost heater shows an open circuit, meaning the heater element must be replaced.
- The defrost thermostat does not close when cooled, preventing the heater from receiving power.
