■ Low-pr essure sensor OPEN/SHORT error determination method
1. Identifies from when power is supplied or 2 minutes after RESET, and only when set is stopped.
2. An E439 error will occur if the
input voltage standard ranges of 0.5V ~ 4.95V of both the high- and low-pressure sensors are
exceeded.
3. Will occur if the measured value of both high- and low-press
ure sensors is 1kgf/cmG
1. Inspection method
Did the
high/low-pressure connector
get disconnected
from the PCB?
Out of the PCB
high-pressure sensor terminals,
is there voltage between
pins 3 and 4 5V?
Replace high/low-pressu
re sensor
Is there refrigerant
inside the set? (Please check by connecting the
menufolder gauge to the
service valve)
Refill refrigerant
after vacuum
Replace PCB
No
Please re-inspect
after connecting the connector
to the PCB
