Error Code
P4
Sub code: 09-11
Method of Error
Detection
Detect the resistance of the following thermistors while the compressor is not running:
Radiation fin thermistor
Thermistor located in PCB circuit
Heat sink thermistor
Error Decision
Conditions
When the resistance of the thermistor comes to a value equivalent to open or short circuit.
Error is not decided while the unit operation is continued.
P4
will be displayed by pressing the inspection button.
Supposed
Causes
Defective radiation fin temperature thermistor
Defective inverter PCB
Defective compressor
Defective fan motor
Troubleshooting
1. 208/230 V and 460 V models: A3P
575 V models: A4P
Make measurement of
resistance of the radiation fin
thermistor.
Is the
resistance of the
relevant thermistor
normal?
The
insulation
resistance of the
relevant compressor is less
than 100 k
.
The insulation
resistance of the relevant
fan motor is less than
1 M
.
Turn ON
the power supply.
Does the error
recur?
