Relevant part Verification method
Electric power
Check the supply.
supply
Check the electrical continu-
Fuse CF2
ity with a tester [fig. 1]
Fuse CF1, Check the electrical conti-
CF3, CF4 nuity with a tester [fig. 1].
Fault is different from the
PCB MAIN
above cases.
Electric power
Check the supply.
supply
Operate with the FAN MO-
TOR disconnected.
13-16kW Unit: remove con-
nectors 11 and 14 and check
the resistance between the
red and black terminals [fig.

FAN MOTOR

2]. If the resistance is greater
than 100kΩ, the FAN MO-
TOR works regularly.
13-16kW Unit: Fuse CF6,
CF7. Check the electrical
continuity with a tester [fig.
2].
Operate with the PUMP
PUMP
disconnected.
Check that the cable con-
nections to the terminals are
correct.
REACTOR
Check the electrical continu-
ity between the terminals of
the REACTOR with a tester
DRAIN TEMP. Check the electrical conti-
SENSOR nuity with a tester [tables].
INTAKE
Check the electrical continu-
TEMP. SEN-
ity with a tester [tables].
SOR
Check the service valve and
Gas leak
the cooling circuit.
Solution
Make sure that the power supply is correct.
If fuse CF2 is blown, replace it and verify whether
there is a short circuit in the connectors of the coil
of the 4-WAY VALVE or the DEFROSTING RESIS-
TANCE [fig. 4, 5]. If there is a short circuit, replace the
component in question.
If fuse CF1, CF2 or CF4 is blown, replace the PCB
MAIN.
Replace the PCB MAIN.
Make sure that the power supply is correct.
If the same error code appears, the PCB MAIN or the
PUMP must be replaced. If a different error code ap-
pears, replace the FAN MOTOR.
If the resistance is less than 100kΩ, replace the FAN
MOTOR.
If fuse CF6 or CF7 is blown, replace the FAN MOTOR
and the fuse.
If the same error code appears, the PCB MAIN or the
FAN MOTOR must be replaced. If a different error
code appears, replace the PUMP.
If the cables are not connected, connect them prop-
erly.
If there is no electrical continuity on the REACTOR,
replace it.
DRAIN TEMP. SENSOR must be replaced.
INTAKE TEMP. SENSOR must be replaced.
Recover the refrigerant and then reload the required
mass.
