Test 1 : Check connections of outdoor unit electrical
components
1. Defective connection of electric
components
2. Outdoor Fan Operation failure
3. Outdoor heat-exchanger clogged
4. Compressor failure
5. Main PCB failure
6. Transistor PCB failure
Check if connector is removed.
Check if the terminal connection is loose.
Check erroneous connection.
Check if cable is open.
>>Upon correcting the removed connector or miss-wiring,
reset the power.
Test 2 : Check outdoor fan, heat-exchanger
Is there anything obstructing the air distribution circuit?
Is there any clogging of Outdoor Heat Exchanger?
Is the Fan rotating by hand when operation is off ?
>> If the Fan Motor is locked, replace it.
Check Outdoor Fan Motor. (Refer to Troubleshooting 26)
>> If the Fan Motor is failure, replace it.
Test 4 : Check compressor
Check Compressor. (PARTS INFORMATION 2)
If Test 1 - 5 do not improve the symptom, change Main PCB.
OK
Test 5 : Check transistor PCB
Check Transistor PCB
>>If Transistor PCB is abnormal, replace it.
