Troubleshooting by Error Code SiME341909EA
208 Part 6 Service Diagnosis
Reference
5.32 Refrigerant Overcharged
Applicable
Models
All outdoor unit models
Error Code
F6
Method of Error
Detection
Detect overcharged refrigerant according to outdoor air temperature, heat exchanger liquid pipe
temperature, and subcooling heat exchanger liquid pipe temperature during test operation.
Error Decision
Conditions
When the amount of refrigerant, which is calculated using outdoor air temperature, heat
exchanger liquid pipe temperature, and subcooling heat exchanger liquid pipe temperature
during test 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 liquid pipe thermistor

Disconnection of subcooling heat exchanger liquid pipe thermistor
Troubleshooting
CHECK 11 Refer to page 269.
Check for the conditions of
mounting of the temperature
sensors of the outdoor air
thermistor, the heat exchanger
liquid pipe thermistor, and
subcooling heating exchanger
liquid pipe thermistor to the piping.
Disconnect the outdoor air
thermistor, the heat exchanger
liquid pipe thermistor, and
subcooling heating exchanger
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 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.
Are the temperature
sensors properly
mounted?
