Samsung Refrigerator Error Code Comp Abnormal current Detection

This error means the refrigerator's control board has detected an abnormal current level at the compressor circuit. It can be triggered by loose wiring, a faulty current sense resistor (R308, rated at 0.09 ohm), a failing compressor, or a restriction in the sealed refrigeration system. The refrigerator displays this code to prevent further damage to compressor components.

Continuing to run the refrigerator with this error active risks further damage to the compressor or control board circuitry. If the compressor is drawing excessive current, it can overheat and fail completely. It is best to address the error promptly and monitor whether the refrigerator is maintaining proper cooling temperatures in the meantime.

Repair costs vary significantly depending on the root cause. A wiring repair or control board component fix may fall in the range of $100 to $250 including labor. Compressor replacement is substantially more expensive, typically ranging from $400 to $700 or more depending on the model and local labor rates. Getting a diagnostic service call first is recommended before committing to a repair.

Some steps, such as inspecting and reseating compressor wiring connections, are accessible to a knowledgeable DIYer. However, testing R308 requires a precision multimeter and comfort working on a control board, and diagnosing a failing compressor or sealed system issue requires professional tools and certification. If basic connection checks do not resolve the fault, a qualified technician should complete the diagnosis.

A power reset may temporarily clear the error code, but if the underlying cause such as a wiring fault, a damaged R308 resistor, or a compressor problem is still present, the code will return. A reset is useful for confirming whether the fault is intermittent, but it is not a repair and should not be relied on as a solution.
