Checking code
Meaning, detecting method
1302
High pressure
abnoramlity 1
(Outdoor unit)
High pressure
When pressure sensor detects
abnoramlity 2
0.098MPa or less just before
(Outdoor unit)
starting of operation, error stop
is observed with code No."1302"
displayed.
1500 Overcharged
1. If the discharge SH
refrigerant
detected during operation (at
abnormality
first detection), the outdoor
unit stops at once. The 3
minutes restart prevention
mode is entered. After three
minutes, the outdoor unit
starts up again.
2. If the discharge SH
detected again within 30
minutes after the outdoor unit
stops (second detection), an
abnormal stop is applied, and
"1500" is displayed.
3. If discharge SH
detected more than 30
minutes after the outdoor unit
stops, the state is the same
as the first detection and the
same operation as 1. above
takes place.
4. The abnormal stop delay
period is in effect for 30
minutes after the outdoor unit
stops. The abnormal stop
delay period LED turns ON
during this time.
2500 Leakage
When drain sensor detects
(water)
flooding during drain pump OFF.
abnormality
Cause
(16) Outdoor unit fan block,
motor trouble, poor
operations of fan controller.
(8)~(16) : Rise in high pressure
caused by lowered condensing
capacity in cooling-only and
cooling-main operation.
(17) Poor operations of solenoid
valves SV1 (Bypass valves
(SV1) can not control rise
in high pressure).
(18) Thermistor trouble
(TH5~TH7).
(19) Pressure sensor trouble.
(20) Control circuit board
thermistor trouble, pressure
sensor input circuit trouble.
(21) Thermistor mounting failure
(TH5~TH7)
(22) No connector for pressure
switch (63H), disconnected wire.
(23) Fuse melting on the control
board (F01 or F02).
(1) Fall in internal pressure
caused by gas leak.
(2) Pressure sensor trouble.
(3) Film breakage.
(4) Coming off of pin in connector
portion, poor contact.
(5) Broken wire.
(6) Pressure sensor input circuit
trouble on control circuit board.
10K is
(1) Excessive refrigerant
charge.
(2) Main circuit board thermistor
input circuit trouble.
(3) Thermistor mounting trouble
(TH11, TH12).
10K is
10K is
(1) Water leak due to humidifier
or the like in trouble.

Checking method & Countermeasure
Check outdoor unit fan
See Trouble check of outdoor
unit fan.
See Trouble check of solenoid
valve.
Check resistance of thermistor.
Check Trouble check of
pressure sensor.
Check inlet temperature and
pressure of sensor with LED
monitor.
Check inlet temperature and
pressure of sensor with LED
monitor.
Check whether the fuse melts.
Check whether the actuator for
the cooling FAN (MF), the 4-way
valve or the solenoid valve is not
short-circuited and broken.
See Trouble check of pressure
sensor.
Refer to the section on judging
the refrigerant volume.
Check the sensor detection
temperature and pressure with
the LED monitor.
Check water leaking of humidifier
and clogging of drain pan.
