5. Troubleshooting
All models
Diagnosis Countermeasure
* For the contents of control, refer to the protective control by controlling
compressor rotation speed and cooling high pressure protective control of
microcomputer control function for corresponding models.
Are the
characteristics of
discharge pipe temperature
sensor
normal?
Is the
discharge pipe temperature
control normal?
NO
YES
Is the
temperature (measured
actually) at detection of
error correct?
YES
YES
Is the
discharge pipe
temperature error persisted
during cooling
operation?
NO
* For the characteristics of discharg
pipe temperature, refer to E39.
YES
NO
NO
Replace discharge pipe
temperature sensor.
Insufcient refrigerant
amount : Recharge
refrigerant by weighing
proper amount on a scale.
Control operation check *.
Defective outdoor unit main
PCB
➞
Replace.
Check unit side:
• Isn’t filter clogged?
• Are adequate indoor,
outdoor unit installation
spaces?
• Isn’t there any short-
circuit of air?
• Isn’t there any fouling,
clogging on indoor heat
exchanger?
2. Error detection method
For the error detection method,
refer to the protective control by
controlling compressor rotation
speed and cooling high pressure
protective control of micro-
computer control function for
corresponding models.
3 .
Condition of error displayed
When discharge pipe
temperature anomaly is detected
2 times within 60 minutes or
this anomalous state is detected
60 minutes continuously
including compressor stop.
4. Presumable cause
• Defective outdoor unit main
PCB
• Defective discharge pipe
temperature sensor
• Clogged filter
• Indoor, outdoor unit
installation spaces
• Short-circuit of air on indoor,
outdoor units
• Fouling, clogging of heat
exchanger
