The reason of fault and solution

F1 1 light communication fault

1、Check whether the connection of the outdoor unit and

indoor unit is one to one, otherwise connect the L, N

and communication line of the indoor unit and outdoor

unit one to one.

2、Measure whether the voltage between the zero line and

the communication line is 18V-30AC half-wave signal,

check whether the communication circuit on the indoor

and outdoor electric control board has been damaged,

otherwise replace it.

3、Check whether the LED on the outdoor power board has

been on, otherwise replace the electric control board.

4、Check whether the unit is abnormal caused by the

external interference, if it is, then find the interfering

source, and removes it.

F2 2 light

ambient temp.

sensor fault

1、 Check whether the resistance of sensor is normal,

otherwise replace it.

2、Check whether the sensor wire is short circuit or open

circuit, and whether the plug is well contacted, whether

there is welding off or rosin joint on the electric control

board, repair it if there is any above.

3、When the 1 and 2 are both normal, then the components

or integrated circuit is damaged, the electric control

board should be replaced.
