5-3 Sequence for trouble diagnosis
5-3-1 Outdoor temperature sensor(OPEN/SHORT)
Reoperation
after connection to
connector PCB
No
Outdoor unit thermistor
self badness (exchange)
No
PCB and sensor are normal.
To perform the test
operation by use of K2
Outdoor unit display
Indoor unit display
How to determine
Reason of error
Er → t1 (Outdoor temperature sensor OPEN/SHORT error)
(Operation) (Timer) (Airflow) (Filter)
Disconnection and short of outdoor temperature sensor
Disconnection or leak of applied sensor
Yes
Yes
Yes
To check the out temperature
sensor is normal or not by use of
out data display part
➞ To check the temperature data is
normal or not after pressing K4 3 times.
At this time, is occurred the difference
between the out temperature and data?
Reoperation after PCB exchange
Is not separated the out
temperature sensor connector from
PCB?(CN41)
At this time, Is not largely
deviate the resistance value from side
table value?
