GE Refrigerator Error Code F303

F303 means the fresh food compartment temperature has exceeded 75°F under conditions that rule out door openings or recent defrost cycles as the cause. Specifically, the fault sets when defrost has not run for one hour, the doors have been closed for one hour, and the fresh food temperature is above 50°F. This points to a genuine cooling system problem rather than a temporary warm-up event. The compressor, fans, sealed system, and thermistors should all be evaluated.

Resetting the control board may temporarily clear the F303 fault code, but if the underlying problem is not repaired, the code will return once the fault conditions are met again. A reset is not a fix and should only be used as part of diagnostics, such as after a component replacement to confirm the repair resolved the issue. Continuing to run the refrigerator with unresolved cooling failure risks food spoilage.

Repair costs vary significantly depending on which component has failed. A thermistor or fan motor replacement typically falls in the range of $100 to $300 including parts and labor. Compressor replacement is substantially more expensive, often ranging from $400 to $700 or more depending on the model and labor rates in your area. A sealed system refrigerant repair involving leak detection and recharge can also fall in the higher range and requires a certified technician.

Some causes of F303, such as a seized evaporator fan motor or a failed thermistor, are accessible repairs for a knowledgeable DIYer with basic tools and a multimeter. However, sealed system issues involving refrigerant require EPA certification to service legally and should be handled by a licensed technician. Start by checking whether the condenser and evaporator fans are running, then test thermistor resistance before assuming a sealed system fault.

No, it is not safe to assume food is at a safe temperature when this code is active. The F303 code indicates the fresh food compartment has reached or exceeded 75°F, which is well above the FDA-recommended maximum storage temperature of 40°F. Perishable items should be moved to another refrigerator or cooler with ice until the unit is repaired and confirmed to be holding temperature correctly.
