F6 – EXTERNAL TEMPERATURE SENSOR ERROR
Cause of Error
Tools Required
Possible Broken Part
Troubleshooting
Procedures
Key Details
Cause: The detection of short circuit or open circuit of
external termperature sensor during the inspection of
outdoor unit control panel, indicated by "external
termperature sensor error".
Inspection path: Sensor → Sensor wire → Connectors →
Outdoor unit control panel
Multimeter, 15KΩ standard sensor
External temperature sensor, outdoor unit control panel.
1.
Check if there's resistance problem, short circuit or open
circuit in the sensor; the resistance value should be
within a reasonable range (15KΩ under the temperature
of 25℃).
Check if the sensor wire is broken.
2.
Check if the terminal connectors are well fixed; check if
3.
the weld between the terminal and the main control
panel is loose and pull the terminal slightly for
inspection if necessary.
Check if the sensor is damp/wet.
4.
Replace the external temperature sensor and check if
5.
the error still exists; if the error disappears, replace the
sensor; if the error still exists, it's possible that the main
control panel is faulted, change the outdoor unit control
panel.
DO NOT USE A SENSOR WITH A VALUE LOWER OR HIGHER
THAN 15KΩ
15
