Detective actuators:
Detective details:
Forecast of cause:
OKOK
OKOK
Outdoor unit main PCB
Active filter module
1. External cause
2. Connector connection failure
3. Main PCB failure
4. Active filter module failure
Check Point 2 : Check connection of connector
Check if connector is removed.
Check erroneous connection.
Check if cable is open.
>>Upon correcting the removed connector or mis-wiring, reset the power.
Check Point 4 : Replace main PCB
If Check Point 1 - 3 do not improve the symptom, change Main PCB.
Check Point 1 : Check external cause at indoor and outdoor (voltage drop or noise)
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.
OKOK
Check Point 3 : Check active filter module
Check Active filter module. (Parts information 5)
>>If Active filter module is abnormal, replace it.
When inverter input DC voltage
is higher than 430V or lower than 110V.
When momentary power cut off
occurred on low voltage
