Samsung Refrigerator Error Code COMP ABNORMAL CURRENT ERROR

This error means the inverter control board has failed to detect the correct position of the compressor motor rotor, which is required to properly drive the compressor. The system has shut down the compressor to prevent damage. The fault can originate from the compressor wiring connections, the inverter PCB, or the compressor itself. A technician will need to inspect all three areas to pinpoint the cause.

When this error is active, the compressor is not running, which means the refrigerator is not cooling. Food safety becomes a concern relatively quickly, typically within a few hours for refrigerator contents and longer for a full freezer. The refrigerator itself is not a fire or electrical hazard in most cases, but you should transfer perishables to an alternate cooler and arrange for service promptly to avoid food loss.

Repair costs vary depending on the failed component. If the fix involves reseating a loose wiring connector, the cost is primarily the service call fee, which typically ranges from $75 to $150. Inverter PCB replacement generally falls in the range of $150 to $400 including parts and labor. Compressor replacement is the most expensive scenario, often ranging from $400 to $700 or more depending on the model and local labor rates. Getting a diagnosis before authorizing repairs is the best way to evaluate whether repair or replacement makes more financial sense.

Some portions of the diagnosis are accessible to a knowledgeable DIYer, such as visually inspecting the U, V, and W wiring connectors for loose or corroded terminals and checking for obvious damage to the wiring harness. However, inspecting inverter PCB solder joints, testing compressor winding resistance, and replacing inverter or compressor components typically require electrical testing equipment and experience with high-voltage appliance circuits. Improper handling of inverter components can be hazardous, so professional service is recommended for anything beyond basic wiring inspection.

A power reset may temporarily clear the error display and allow the compressor to attempt a restart, but if the underlying fault is still present, the code will return quickly. Resetting is useful as a first step to determine whether the fault is intermittent, but it does not repair wiring faults, PCB defects, or compressor failures. Repeated resets without addressing the root cause will not resolve the problem.
