daikin pcb problem

[hwtan]

i do my own servicing for this daikin model
ftkd71jve

by removing the drainage tray and plugging out the swing louver motor, cleaning the rotor etc..

but after putting back everything, plug back the cables, try switching on but totally not moving

even though have reset the main power, the louver suppose to auto swing back into position, but is not moving either.

what is happening here?

this is not the first time i'm doing it.

any advice??

Motor drive and louvre spindles all lined up and connected?

yes.

[hwtan]

yes.

even by pressing the manual button, it wouldn't work.

if you plugged the loads back into the printed circuit board with the power on you may have damaged the printed circuit board.

the load you mean is which part?

i just plug back the swing louver motor cable (which is running in low voltage)

if the unit power was on this can damage the board and motor.

had been cleaning it a couples of times and this is the first time this problem is happening.
