Are
the characteristics of
outdoor heat exchanger
temperature sensor
normal?
Is
the temperature
(measured actually) at
direction of error
correct?
NO
YES
YES
Is the
unit operating in
the state of cooling
overload?
Is the high
pressure control
normal?
YES
YES
* For the characteristics of outdoor
heat exchanger temperature
sensor, refer to E37.
NO
NO
NO
* For the contents of control, refer to cooling high pressure protective control
in the protective control by controlling compressor rotation speed of
microcomputer control function for corresponding models.
Replace outdoor heat
exchanger temperature
sensor.
Check unit side.
• Isn’t the air circulation
of outdoor unit short-
circuited?
• Are installation spaces
adequate?
• Isn’t there any fouling
or clogging on heat
exchanger?
Control operation check*

Replace.
Excessive refrigerant
amount: Recharge
refrigerant by weighing
proper amount on a scale.

Outdoor heat exchanger temperature (°C)
Note(1) Values in ( ) are appli-
cable when outdoor air
temperature (TH2) is
lower than 32°C
3 . Condition of error displayed
When anomalous outdoor heat
exchanger temperature occurs
5 times within 60 minutes or
60(56)°C or higher continues
for 10 minutes, including the
compressor stop
4. Presumable cause
• Defective outdoor heat
exchanger temperature sensor
• Defective outdoor unit control
PCB
• Indoor, outdoor unit
installation spaces
• Short-circuit of air on indoor,
outdoor units
• Fouling, clogging of heat
exchanger
• Excessive refrigerant quantity
