F0
Upon turning ON, fan motor does not
turn, this may mean that the motor is broken
Testing the motor winding resistance is normal, if the nor
mal please plug again two butt plugs, if abnormal, please
replace the motor.
Without the zero signal
Reference indoor machine circuit diagram to ensure zero
crossing detection circuits without welding, welding, cont
rol circuit diagram tagging model of device parameters
such as resistance, voltage measurement, if the device is
damaged, please replace the same type of device.
No control signal
Reference indoor machine circuit diagram to ensure that
PG motor control circuit device without welding, welding,
control circuit diagram tagging model of device
parameters such as resistance, voltage measurement, if
the device is damaged, please replace the same type of
device.
Fan motor short running after the F0, which indicates
that the motor feedback signal wire broken, no feedb
ack signal
Turn the motor measurement feedback line 1/2 feet
without output, motor is bad, replace the motor.
F1-F5
Reference indoor machine circuit diagram to ensure
that PG feedback circuit device without welding,
welding, control circuit diagram tagging model of
device parameters such as resistance, voltage
measurement, if the device is damaged, please
replace the same type of device.
To insert the terminal socket, accordingly to ensure good
contact
Poor contact sensor socket
Replacement of the same model sensor
