Display
F3
Subcode 19
Applicable Models
All indoor units
Method of
Malfunction
Detection
Abnormality is detected according to the temperature detected by the discharge pipe temperature sensor.
Malfunction
Decision Conditions
When the discharge pipe temperature rises to an abnormally high level
When the discharge pipe temperature rises suddenly
Supposed Causes
Faulty discharge pipe temperature sensor (R6T)
Faulty connection of discharge pipe temperature sensor
Faulty indoor unit PC board
Troubleshooting
Refer to “Thermistor Resistance / Temperature Characteristics” table on page 251.
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts may be damaged.
Discharge
pipe temperature is
120 C or higher when the
unit stop by
malfunction
.
Pull out the discharge pipe
thermistor (X12A [1,2] on A4P)
from the indoor PC board, and
then make measurement of
resistance using a multiple meter.
Replace indoor unit PC board
(A4P).
Replace the discharge pipe
thermistor (R6T).
NO
