Troubleshooting       

  * Caution    Be sure to turn off power switch before connect or disconnect connector,      or parts damage may be occurred. 

Check whether Terminal on the outdoor

mainboard is well inserted.

it is normal

Reinsert the terminals

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 switch 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

.

The module pcb is

damaged, replace it

with a new one.

The

outdoor pcb

is

damaged, replace it
