Samsung Refrigerator Error Code COMP Run failure ERROR

This error means the refrigerator's compressor attempted to start but failed to do so successfully. The inverter PCB, which controls compressor power and speed, is typically the first area to inspect. Diagnostics focus on the inverter board's solder condition, its DC 16V output voltage, and the compressor itself. The fridge will not cool properly while this error is active.

The refrigerator will not maintain safe food storage temperatures when the compressor cannot run, so food spoilage is a real risk. There is no immediate safety hazard to the home or occupants, but the appliance should not be relied upon to keep food cold until the error is resolved. Transfer perishable items to another refrigerator or cooler while the repair is pending.

Repair costs vary widely depending on the failed component. Inverter PCB replacement typically ranges from around $150 to $400 including parts and labor. Compressor replacement is significantly more expensive, often ranging from $400 to $700 or more depending on the model and labor rates in your area. Sealed system repairs involving refrigerant will add further cost. Getting a diagnostic quote before authorizing any parts replacement is advisable.

Some parts of the diagnosis, such as checking wiring connections for looseness or corrosion, can be performed by a knowledgeable DIYer. However, testing inverter PCB output voltage, inspecting solder joints, and evaluating compressor windings requires a multimeter and comfort working with refrigerator electronics. Sealed system refrigerant work must be performed by a licensed technician. For most homeowners, professional service is the recommended approach.

A power reset may temporarily clear the error display, but if the underlying cause, such as a low inverter voltage output, a solder defect, or a failing compressor, has not been corrected, the error will return. Resetting without diagnosing the root cause can delay proper repair and risk extended food loss. A reset is useful only as a first step to see whether the error is intermittent or persistent.
