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 (over 135°C)
When the discharge pipe temperature rises suddenly (over 120°C continues 10 min.)
Supposed
Causes
Faulty discharge pipe temperature sensor
Faulty connection of discharge pipe temperature sensor
Faulty outside unit PC board
Troubleshooting
Connect the Service Checker.
Restart operation after resetting
operation.
1: Compare the resistance values of the discharge pipe thermistor with
measurements of a surface thermometer.
(For temperature and resistance characteristics of a thermistor, refer to
page 309, 310.)
2: Compare the discharge pipe temperature checked by the Service
Checker with the resistance of the thermistor (refer to 1).
The discharge pipe thermistor is normal and the main PC
board temperature detection is also normal.
In fact, discharge pipe temperature is rising.
: Refer to page 263 to eliminate the causes of
overheat operation.
CHECK 3
Is
PC board detection
temperature normal?
(2)
Replace the main PC board.
NO
YES
Replace the discharge pipe
thermistor.
