Diagnosis
Countermeasure
After
resetting power for
several times does it
become normal?
NO
YES
Temporary noise may cause of anomaly.
If noise source can be found, take countermeasure.
Is the
checked result of power
transistor module
OK?
NO
• Is the space for installation of indoor and/or outdoor unit enough?
• Is there any short circuit of air on indoor and/or outdoor unit?
• At cooling, does the outdoor fan motor run?
Are the service valves fully opened?
Is the filter clogged?
• At heating, does the indoor fan motor run?
Are the service valves fully opened?
Is the filter clogged?
• Is there any liquid flooding?
Is the superheat within normal range?
Is the low pressure sensor and suction pipe temperature
thermistor normal?
• Is there any anoumalous sound on the compressor?
YES
YES

2. Error detection method
In order to prevent from
overcurrent of inverter,
if the current exceeds the
specifications, it makes the
compressor stopping.
3.
Condition of Error displayed
•
If the output current of inveter
exceeds the specifications,
it makes the compressor
stopping.
•
After 3-minute delay, the
compressor restarts, but if this
amonaly occurs 4 times within
30 minute after the intial
detection.
4. Presumable cause
• Defective inverter PCB
• Faulty power supply
• Insufficient refrigerant amount
• Faulty compressor
• Faulty power transistor
