P06
HPS check
J061
Abnormal OFF point (1) HPS malfunction
(2) High pressure transducer
(HPT) malfunction
(3) Gas leak from Gauge
manifold
(No unit malfunction)
(1) Check HPS
(2) Compare to Gauge
manifold
(3) Remove Gauge
manifold.
P08
Pump down check
J081
Pump down
requires too long
time.
Blocked with contamination of
liquid solenoid valve
Try again S-PTI
P10
Solenoid valve
check
J101
Excessive
leakage of
solenoid valve
Liquid solenoid valve malfunction Check Liquid solenoid valve
P12
RS, SS accuracy
check
J121
Excessively large
temperature
difference between
RS and DRS
Excessively large
temperature
difference between
SS and DSS
SS malfunction
Compare the SS with
the DSS on the
controller panel.
P14
HPT, LPT
accuracy check
J141
Excessively large
pressure
difference
between HPT
and LPT
HPT malfunction
Compare the high pressure
valve with the gauge manifold of
HPT (on the controller panel).
P20
Check on economizer
solenoid valve (ESV)
J201
ESV does not
open.
ESV coil malfunction
Check on ESV coil, wiring
and terminals.
P16
Evaporator fan
Hi/Lo speed
operation check
J161
Abnormal operation
of evaporator fan
speed
Evaporator fan and motor malfunction.
Magnetic contactor (EFH/L) and wiring
malfunction.
Check Evaporator fan and motor.
Check magnetic contactor
(EFH/L) and wiring.
J062
Not return
J064
High pressure does not rise.
J065
High pressure does not drop.
Leakage of hot gas by-pass
solenoid valve
Touch the outlet pipe of
the solenoid valve.
Leakage of defrosting solenoid
valve
Touch the outlet pipe of
the solenoid valve.
Leakage of discharge gas by-
pass solenoid valve
Touch the outlet pipe of
the solenoid valve.
Suction modulating valve malfunction Check Suction modulating valve
Injection valve malfunction
Check Injection valve
RS malfunction
Compare the RS with
the DS on the controller
panel.
LPT malfunction
Compare the low pressure
valve with the gauge manifold
of LPT (on the controller panel)
ESV malfunction
Check on capillary tube
temperature on ESV outlet.
