OUTDOOR UNIT Error Method:

Inverter Error

Detective Actuators:
Inverter PCB
Forecast of Cause : 1. Noise, momentary open, voltage drop. 2. Power supply to Filter PCB (INV) to Inverter PCB
wiring disconnection, open 3. Filter PCB ( INV) defective 4. Inverter PCB defective
5. Cement Resistor Open circuit
Check Point 1-1 : Turn the power
on again.
Error displayed again?
YES
Check Point 2 : Check the wiring (Power supply to Filter PCB (INV) to Inverter PCB)
Connector and wiring connection state check
Cable open check
OK
Check Point 3 : Check Cement resistor
Check resistance of cement resistor
If the circuit of both terminal was open circuit, exchange the Resistor
Correct resistance value: 5.3 - 6.0 Ohm
OK
Check Point 4 : Check Filter PCB (INV) and Inverter PCB
Check Filter PCB (INV) and Inverter PCB.
