What the F Comp Start Failure Error error code actually means

This error means the freezer's compressor, the pump that keeps your freezer cold, tried to turn on but failed to start. Your freezer will stop cooling until the problem is identified and corrected. The issue could be a faulty circuit board, low voltage supply, or a compressor that has worn out.

Questions people ask about F Comp Start Failure Error

What does F Comp Start Failure Error mean on a Samsung refrigerator?
This error means the freezer compartment compressor attempted to start but failed to do so within the expected timeframe. The Samsung control system monitors the inverter PCB and compressor startup sequence, and when startup does not occur, it logs this fault and halts operation. The cause can range from a board-level issue on the F Room inverter PCB to a failed compressor or refrigerant system problem.
Will resetting the refrigerator clear the F Comp Start Failure Error?
A power reset may temporarily clear the error display, but the code will return if the underlying cause is not corrected. If the compressor still fails to start after a reset, the fault condition persists and the freezer will not cool. A reset is useful for ruling out a one-time glitch but should not be relied on as a repair.
How much does it cost to repair the F Comp Start Failure Error on a Samsung refrigerator?
Repair costs vary significantly depending on the root cause. Replacing the F Room inverter PCB typically falls in the range of $150 to $350 including parts and labor. Compressor replacement is substantially more expensive, often ranging from $400 to $800 or more depending on the model and labor rates in your area. Getting a professional diagnosis first helps avoid replacing parts that are still functional.
Can I fix the F Comp Start Failure Error myself?
Some steps are accessible to a knowledgeable DIYer, such as inspecting wiring connectors and checking for visible solder defects on the inverter PCB. However, measuring the DC 15V output on the inverter board requires a multimeter and comfort working near live components. Diagnosing a failed compressor or evaluating refrigerant pressures requires professional tools and, for refrigerant work, EPA certification.
Is it safe to continue using my refrigerator while this error is showing?
The freezer section will not cool properly while this error is active, meaning frozen food is at risk of thawing and spoiling. The refrigerator compartment may also be affected depending on the system configuration. It is best to remove perishable items from the freezer and address the fault promptly rather than continuing to run the appliance.
