Samsung Refrigerator Error Code Comp Start Failure Error

The Comp Start Failure Error means the refrigerator's compressor attempted to start but did not successfully complete its startup cycle. The main control board detected the failure and logged the fault code. This error typically results in the refrigerator losing cooling capacity. The cause can range from a wiring issue to a faulty PCB component or a failed compressor.

A power cycle reset may temporarily clear the error code and allow another startup attempt, but if the underlying fault is still present, the error will return. Resetting does not fix wiring faults, PCB component failures, or a mechanically failed compressor. The reset should be used as a diagnostic step, not a solution.

Repair costs vary widely depending on the root cause. A solder joint reflow or connector repair might cost between $75 and $150 in labor. Replacing the main PCB typically runs between $150 and $350 for parts and labor. A compressor replacement is the most expensive scenario, often ranging from $300 to $700 or more depending on the model and labor rates in your area.

Some steps are DIY-friendly, such as checking and reseating wiring connectors at the compressor and inspecting the main PCB for visibly cracked solder joints. However, verifying resistor R2 at 0.09 ohms requires a multimeter and basic electronics knowledge. Diagnosing a failed compressor or refrigerant cycle issue requires professional tools and is best left to a certified technician.

When this error is active, the compressor is not running, which means the refrigerator is not maintaining safe temperatures for food storage. Perishable foods should be moved to another refrigerator or cooler as soon as possible. Continuing to operate the unit without addressing the fault will not cause a safety hazard in terms of fire or electrical danger, but food spoilage is a real concern.
