Trouble shooting 36
OUTDOOR UNIT Error Method:
Current Sensor Error
(only for Master Unit)
Indicate or Display:
Outdoor Unit : LED1 Flash, LED4 4 Times Blink
Indoor Unit : Operation LED
ERROR CODE : E : 32
Detective Actuators:
Outdoor Unit Controller PCB circuit
Current Sensor
Detective details:
When Current Sensor has detected an error for 2 times in a row while Inverter
Compressor is operating at higher than 50Hz.
Check Point 2 : Check connections of Outdoor
Unit Electrical Components
If the symptom does not change with above Check
1,2,3, Current Sensor may be defective. Replace
Current Sensor.
Check Point 3 :
Check Filter PCB and Inverter PCB
Check Point 4 : Replace Current Sensor
Check Point 1-1 : Restart Operation
YES
NO
Does LED error indication reappear?
p Isn’t the terminal connection loose?
p Is Current Sensor Connector secure?
p Check connection between Inverter PCB and Filter PCB.
(If there is loose connector or open cable)
p Check Filter PCB and Inverter PCB.
(PARTS INFORMATION 4)
OK
OK
Forecast of Cause : 1. Electrical Component failure 2. Outside Cause 3. Filter PCB failure 4. Inverter PCB failure
5. Current Sensor failure
Check Point 1-2 :
Check outside cause (Voltage drop or noise, etc.)
Instant drop ----- Check if there is a large load electric apparatus
in the same circuit.
Momentary power failure ----- Check if there is a defective
contact or leak current in the
power supply circuit.
Noise ----- Check if there is any equipment causing harmonic
wave near electric line (Neon bulb or electric
equipment that may cause harmonic wave).
Check the complete insulation of grounding.
