Electrify the machine again and turn it on in
the Cool state with the remote controller.
check whether the motor could run
.
Remove fan motor after s witch off
the power.
Measure the resistances
between black line (0V) and red
line( 310V),between black line(0V)
and white line (15V) of the fan
motor .
NO
YES
The resistances are
greater than 40K
Ω
NO
YES
The motor of the outdoor unit is
damaged and needs replacing.
NO
the resistances between 0V
and 310V,between 0V and 15V of
the fan terminal of outdoor pcb are
greater than 10M
Ω
.
