Samsung Air Conditioner Error Code E570

E570 indicates an Inverter DC Link sensor error in the outdoor unit. The DC link is the high-voltage DC bus inside the inverter drive that powers the variable-speed compressor. This code means the sensor monitoring that bus has detected an out-of-range value or has lost its signal entirely. It points to a hardware fault in the inverter section that requires professional diagnosis.

No, continuing to operate the unit with an active E570 fault is not recommended. The error indicates a problem in the inverter drive circuit, and running the system could cause additional damage to the inverter board, compressor, or other components. Power the unit off at the breaker until a technician can diagnose the fault.

Repair costs vary depending on the specific failed component. Inverter control board replacement typically falls in the range of $200 to $600 including parts and labor. Capacitor replacement at the component level is generally less expensive, while an IPM or compressor drive module replacement can push costs higher. Getting a diagnostic inspection first will help determine the exact scope and cost of the repair.

This error involves the high-voltage inverter circuit inside the outdoor unit, where DC link voltages can reach several hundred volts and capacitors can hold that charge for several minutes after power is removed. Component-level repair requires proper tools, discharge procedures, and electrical knowledge. Most homeowners should not attempt this repair, and it is best handled by a certified HVAC or refrigeration technician.

A power reset may temporarily clear the displayed code, but if an underlying hardware fault exists such as a failed capacitor, damaged board, or wiring problem, the error will return once the unit attempts to operate. A reset is not a repair, and the root cause must be identified and corrected to resolve E570 permanently.
