Samsung Air Conditioner Error Code E385

E385 indicates an error related to the input current of Inverter 2, the second inverter PCB responsible for controlling compressor speed. The system detected that the input current is outside acceptable operating limits. This is a protective shutdown to prevent damage to the inverter board and compressor. A qualified technician should inspect and likely replace the inverter PCB to resolve this fault.

A power reset may temporarily clear the error display, but if the underlying inverter PCB or electrical fault remains, the E385 code will return once the unit attempts to operate again. Resetting does not repair the faulty component. Persistent reappearance of E385 after a reset confirms that a hardware fault requires attention.

Repair costs depend on whether the issue is a wiring or connection problem versus a full inverter PCB replacement. Labor charges for diagnosis and repair typically range from $80 to $200 or more depending on your region and the complexity of accessing the inverter. If the inverter PCB itself requires replacement, parts costs can add another $150 to $500 or higher depending on the specific unit model. Getting a written estimate before authorizing parts replacement is advisable.

This repair is not recommended for untrained individuals because it involves high-voltage components inside the inverter section of the unit. The primary repair step is replacing the inverter PCB, which requires safely discharging capacitors and handling live electrical assemblies. A licensed HVAC or appliance technician should perform this diagnosis and repair.

No, you should not attempt to continue running the unit while E385 is active. The error indicates an inverter input current fault, and continued operation could cause further damage to the inverter board, compressor, or associated electrical components. Leave the unit powered off until the fault is diagnosed and repaired by a technician.
