Current sensor error
Current Sensor Error – When input current sensor has detected 0A, while the inverter compressor is operating at
higher than 56rps, after 1 minute upon starting the compressor. (Except during defrost operation)
-Check if terminal connection is loose.
-Check if connector is removed.
-Check if erroneous connection.

Pressure sensor error
Pressure Sensor Error – Detects after 30 seconds or more after power up when the pressure sensor detection
value detects the condition below continuously for 30 seconds or more:
•
Ps≤ 37.71 psi (-0.26 Mpa) or Ps ≥ 816.56 psi (5.63 Mpa)
-Check connection of pressure sensor; check if terminal connection is loose, connector is removed, connector
has erroneous connection, cable is open.
-Check voltage of main PCB.

Over current error
Over Current Error – Protection stop by overcurrent generation after inverter compressor start processing com-
pleted generated consecutively 10 times. The number of generations is reset if the start-up of the compressor
succeeds.
-Clogged heat exchanger.
-Condenser fan motor defective.
-Discharged air not sucked in.

Compressor control error
Compressor Motor Control Error – If the detected rotor location is out of phase with actual rotor location more
than 90 degrees, the compressor stops. After the compressor restarts, if the same operation is repeated within
40 seconds, the compressor stops again.
-Check if connector is removed.
-Check erroneous connection.
-Check if cable is open.

Outdoor unit fan motor
error
Outdoor Unit Fan Motor Error – When outdoor fan motor rotation speed is less than 100 RPMs in 20 seconds
after fan motor starts, fan motor stops. After fan motor restarts, if the same operation within 60 seconds is
repeated 3 times in a row, compressor and fan motor stops.
-Check rotation of fan, locked motor, or resistance for motor to rotate.
-Check ambient temperature around motor, excessive high temperature around motor or surrounding equip-
ment that causes heat.
-Ohm fan motor windings, check for DC voltage to motor.

Outdoor unit fan motor 2
error
Outdoor Unit Fan Motor 2 Error – When the outdoor fan rotation speed is less than 100 RPMs in 20 seconds
after the fan motor starts, the fan will stop. After motor restarts, if same operation within 60 seconds is
repeated 3 times in a row, compressor and fan stop. If above repeats 5 times in a row, compressor and fan stop
permanently.
-Check rotation of fan, locked motor, or resistance for motor to rotate.
-Check ambient temperature around motor, excessive high temperature around motor or surrounding equip-
ment that causes heat.
-Ohm fan motor windings, check for DC voltage to motor.
