Service Diagnosis
3.41 Refrigerant Overcharged
Error Code
F6
Applicable
Models
All outdoor unit models
Method of Error
Detection
Detect overcharged refrigerant according to outdoor air temperature, heat exchanger deicer
temperature, and liquid pipe temperature during check operation.
Error Decision
Conditions
When the amount of refrigerant, which is calculated using outdoor air temperature, heat exchanger
deicer temperature, and liquid pipe temperature during check operation, exceeds the regular
charge amount by 30% or more
(If refrigerant is charged slightly over the regular charge amount,
F6
may be displayed on the
remote controller.)
Supposed
Causes
Refrigerant overcharged
Disconnection of outdoor air thermistor
Disconnection of heat exchanger deicer thermistor
Disconnection of liquid pipe temperature thermistor
Troubleshooting
Check for the conditions of
mounting of the temperature
sensors of the outdoor air
thermistor, the heat exchanger
thermistor, and liquid pipe
thermistor to the piping.
Disconnect the outdoor air
thermistor, the heat exchanger
thermistor, and liquid pipe
thermistor from the outdoor
unit main PCB, and then make
measurement of resistance
using a multimeter.
Normal?
Remedy refrigerant overcharging.
YES
NO
NO
Replace the abnormal thermistors,
and then operate the system.
Properly connect the thermistors,
and then operate the system.
YES
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
CHECK 11
Are the temperature
sensors properly
mounted?
CHECK 11
