Samsung Refrigerator Error Code Detecting Position Failure

This error means the compressor inverter board cannot detect the rotor position inside the compressor motor, and it is indicated by a specific blink pattern on the inverter LED. The inverter needs accurate rotor position data to properly drive the compressor. When that signal is lost or invalid, the system shuts down the compressor and displays this fault. The root cause is typically a wiring connection problem, a failed compressor, or a faulty inverter PCB.

With this error active, the compressor is not running correctly or may have shut down entirely, meaning the refrigerator will not maintain safe food storage temperatures. It is not advisable to continue relying on the unit to keep food cold until the fault is diagnosed and repaired. Perishable food should be moved to another cooler or refrigerator promptly.

Repair costs vary depending on which component has failed. Connector-only repairs may cost very little if no parts are needed. An inverter PCB replacement typically ranges from around $100 to $250 or more including the part and labor. Compressor replacement is the most expensive repair, often ranging from $300 to $700 or higher depending on the model and local labor rates.

The first diagnostic step, checking the inverter connectors, is something a knowledgeable DIYer can attempt by inspecting for loose or corroded connections on the inverter harness. However, replacing the compressor is a complex repair that involves handling refrigerant and requires EPA certification in the United States. Replacing the inverter PCB is more accessible but still requires careful handling of electrical components.

A power reset may temporarily clear the error display, but if the underlying fault is still present, the error will return once the inverter attempts to start the compressor again. Resetting does not fix the root cause, which requires physical inspection of the connectors, compressor, or inverter board. A reset can be useful to confirm whether the fault is persistent or intermittent.
