What the 0315 error code actually means

Your GE refrigerator is detecting that the refrigerator section is not getting cold the way it should, even though the cooling system was asked to cool it. This is most often caused by a valve that directs cold refrigerant into the refrigerator failing to open properly, or by a sensor that measures the temperature inside the cooling coil giving a bad reading. Until this is fixed, your refrigerator section may not stay at a safe temperature.

Questions people ask about 0315

What does 0315 mean on a GE refrigerator?
Code 0315 means the control board is not detecting cooling at the refrigerator compartment evaporator coil when it expects to see it. GE refrigerators with this error use a 3-way valve to direct refrigerant between the freezer and refrigerator evaporators, and this code points to a failure in that process. Common causes include a stuck 3-way valve, a failed evaporator thermistor, or a refrigerant issue.
Is it safe to keep using my refrigerator when code 0315 is showing?
If this code is active, the refrigerator compartment may not be maintaining a safe food storage temperature, which is generally considered 40 degrees Fahrenheit or below. Food safety is at risk if the compartment is warming up. It is best to check the actual temperature inside the refrigerator section and move perishables if it is not staying cold enough.
How much does it cost to repair a GE refrigerator showing code 0315?
Repair costs vary depending on the root cause. A replacement thermistor is generally an affordable fix, typically in the range of $20 to $60 for the part. A 3-way valve replacement can cost more, often $80 to $200 or more for the part plus labor. If the sealed refrigerant system is involved, total repair costs including labor and refrigerant can range from $200 to $600 or higher.
Can I fix error code 0315 on my GE refrigerator myself?
Some causes, such as a failed evaporator fan motor or a faulty thermistor, are within the ability of a skilled DIYer to diagnose and replace. However, if the root cause involves the refrigerant system or a sealed-system component, a licensed technician is required to handle refrigerant legally and safely. Diagnosing the 3-way valve also requires access to wiring diagrams and a multimeter to check coil resistance and power delivery.
Will resetting my GE refrigerator clear error code 0315?
A reset may temporarily clear the code from the display, but the code will return if the underlying problem has not been repaired. To reset, you can unplug the refrigerator for a few minutes and restore power. If the fault condition still exists, the control board will detect the same cooling failure and log the code again.
