What 0315 means on a GE refrigerator

Error code 0315 on a GE refrigerator indicates that cooling is not being detected at the refrigerator compartment evaporator in a system that uses a 3-way valve. The 3-way valve is responsible for directing refrigerant flow between the freezer evaporator and the refrigerator evaporator, or both simultaneously, depending on the cooling demand. When the control board calls for refrigerator compartment cooling and the expected temperature drop at the evaporator does not occur within a defined time window, the board logs this fault code.

The most likely causes involve the 3-way valve itself failing to open the refrigerator evaporator circuit, a loss of refrigerant charge, or a blocked refrigerant path. The 3-way valve is an electromechanical component that can fail in a closed or stuck position, preventing refrigerant from reaching the refrigerator evaporator coil. A thermistor or temperature sensor positioned at the refrigerator evaporator is used to confirm cooling is taking place, so a failed sensor can also trigger this code even if the refrigerant system is functioning normally. Additionally, a weak or failed compressor, a dirty or iced-over evaporator coil, or a faulty evaporator fan that prevents airflow across the coil can all contribute to this fault condition.

Common causes of 0315

  1. 01

    Failed or stuck 3-way valve

    Part replacement

    The 3-way valve may be stuck in a position that blocks refrigerant flow to the refrigerator evaporator. Check for power to the valve coil and listen for an audible click when the valve is energized.

  2. 02

    Faulty refrigerator evaporator thermistor

    Part replacement

    The temperature sensor at the refrigerator evaporator may be reading incorrectly, causing the control board to believe cooling is not occurring even when it is. Check the thermistor resistance and compare it against the expected range for the measured ambient temperature.

  3. 03

    Low or lost refrigerant charge

    Part replacement

    A refrigerant leak can reduce system capacity to the point where the refrigerator evaporator never reaches the required temperature. Look for oily residue near refrigerant line connections as a possible sign of a leak.

  4. 04

    Iced-over refrigerator evaporator coil

    Wiring / connection

    If the defrost system has failed, ice buildup on the evaporator coil can block airflow and prevent effective heat exchange. Inspect the coil for excessive frost accumulation after removing the evaporator cover panel.

  5. 05

    Refrigerator evaporator fan failure

    Part replacement

    If the evaporator fan motor is not running, cold air will not circulate across the coil and into the refrigerator compartment, triggering the cooling not detected fault. Confirm the fan is spinning freely and receiving proper voltage.

Frequently asked questions 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.
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.
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.
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.
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.
