GE Refrigerator Error Code 0304

Code 0304 means the GE refrigerator's control board has detected that the freezer temperature has exceeded 25°F. This is above the safe threshold for frozen food storage. The code is triggered by the freezer thermistor reading and indicates the refrigeration system is not maintaining adequate cooling in the freezer compartment.

Start by checking the basics: confirm the freezer door seals are intact, the condenser coils at the back or bottom of the unit are clean, and the evaporator fan is running when you open the freezer. If frost has built up heavily on the back wall of the freezer, the defrost system may have failed. If none of these are the issue and the compressor is running but not cooling, a refrigerant leak or sealed system failure is likely, which requires a certified technician.

On most GE models, this code will clear once the freezer thermistor reads a temperature back within the acceptable range. However, if the underlying cause has not been fixed, the temperature will rise again and the code will return. A recurring 0304 code confirms a persistent mechanical or component failure that needs to be diagnosed and repaired rather than simply reset.

No, it is not safe to rely on the freezer for food storage while this code is active. A freezer temperature above 25°F means frozen foods may be partially thawing, which creates food safety risks. Move frozen items to another freezer or use ice if available, and address the underlying cause before restoring normal use.

Cost depends on the root cause. Cleaning condenser coils costs nothing if you do it yourself. Replacing an evaporator fan motor typically runs $80 to $200 in parts, with an additional $100 to $150 in labor if professionally repaired. Defrost system components such as the heater or thermostat are generally $20 to $60 in parts. Refrigerant leak repair or sealed system work can cost $300 to $600 or more and must be performed by an EPA-certified technician.
