Samsung Air Conditioner Error Code E568

E568 indicates an inverter compressor rotation error. The control system has detected that the compressor motor is not rotating as commanded or has stalled during operation. This triggers a protective shutdown to prevent damage to the compressor or inverter components. The root cause can be electrical, mechanical, or refrigerant-related.

No. The E568 error triggers a protective shutdown for a reason, and attempting to force the unit to operate with this fault active can cause additional damage to the compressor or inverter board. Leave the unit off and have it inspected before resuming normal use.

A power reset may temporarily clear the fault code and allow the unit to attempt a restart, but if the underlying problem has not been resolved, the error will return quickly. A reset is not a repair. Continuing to reset and restart the unit without addressing the cause can lead to more serious and costly damage.

Some basic checks, such as cleaning a blocked condenser coil or verifying the unit has adequate airflow, can be done by a homeowner. However, diagnosing the inverter PCB, testing compressor winding resistance, and checking refrigerant pressures require specialized tools and training. Inverter circuits also carry dangerous high voltages, so internal electrical diagnosis should be left to a qualified technician.

Repair costs vary depending on the root cause. Cleaning a condenser coil or recharging refrigerant may cost in the range of $100 to $300. Replacing an inverter PCB typically runs $200 to $600 including parts and labor. If the compressor itself has failed, replacement costs can range from $500 to over $1,500 depending on the unit size and installation complexity.
