[ CHECK 2 ]
Forecast of Cause :
1. Valve is close 2. EEV, Solenoid Valve failure 3. Gas Leak, less 4. Discharge Thermistor failure
5. Outdoor Fan Operation failure 6. Outdoor Heat Exchanger clogged
Check Point 1 : Check if Gas Valve is open
p
If it is not open, open it and check the operation.
(If Liquid valve close, High pressure error.)
Check Point 3 : Check if gas leak or less gas
p
Measure Gas pressure, if there is a leak, correct it.
>>If recharging refrigerant, make sure to perform vacuuming and
recharge the specified amount.
Check Point 5 : Check Outdoor FAN, Heat Exchanger
p
Is there anything obstructing the air distribution circuit?
p
Is there any clogging of Outdoor Heat Exchanger?
p
Is the Fan rotating? (Check by hand and if it is locked, replac e the motor)
p
Check Outdoor Fan Motor
(PARTS INFORMATION 12)
>>If the Fan Motor is defective, replace it.
Check Point 4 : Check Discharge Thermistor 1
p
Isn’t it fallen off the holder?
p
Is there a cable pinched?
>>
Check characteristics of thermistor (Refer to Trouble shooting 24),
If defective, replace the thermistor
.
Check Point 2 : Check EEV, Solenoid Valve and Strainer
p
Is EEV (EEV2, Indoor unit EEV) open?
(PARTS INFORMATION 5,7)
(PARTS INFORMATION 6)
p
Is Liquid side Strainer open?
(PARTS INFORMATION 5)
p
Is Solenoid Valve (SV4 of Main Unit) open?
(PARTS INFORMATION 9)
p
Is Solenoid Valve (SV4 of Slave Unit) open?
(PARTS INFORMATION 9)
>>If EEV or Solenoid Valve or Strainer is defective, replace it.
OK
Check Point 1 : Check if Liquid Valve is open
p
If it is not open, open it and check the operation.
(If Gas valve close, High pressure error.)
OK
Check Point 2 : Check if EEV1, SV4 is open
p
Is EEV (EEV1) open?
If the service tool is connected, check if there is an
indoor unit that is extremely low heat exchanger
temperature.
(On heating, the refrigerant flows to the stopped
indoor unit as well.)
