Is power supply good?
yes
Is indoor status
indication good?
Is fuse in good condition?
Replace fuse
when there is no
short-circuit
Is there any other
broken component?
check any other
reasons
Is output voltage of
fan motor good?
Is fan capacitor
in good
condition?
Is fan motor winding
resistor normal?
Wrong fault code. Check
other possible causes. E.g.
motor is stuck
Replace fan
capacitor
Replace PCB
No. It's split winding type motor
Is it a PG motor? As in
AS and AF indoor units
Is output voltage good
when energized? Does fan
motor run properly?
Is there DC voltage
feedback from motor
during running?
Signal detecting circuit has
a problem. Replace PCB
Replace motor
Is front-end voltage of
thyristor good?
Supply circuit has a
problem. Replace PCB
Thyristor or control
circuit has a problem.
Replace PCB
Is front-end voltage
of fan speed relay
good?
Is voltage of fan speed
relay coil 12VDC?
Supply circuit has a
problem. Replace PCB
Controller chip has a
problem. Replace PCB
Fan speed relay is
broken, replace PCB
Is there any poor
connection?
Reconnect
