Check the power supplier if the power supplier is supplied to the
unit. Check the power cord and correct if damaged.
Check resistance between the two input/output lines on
transformer. Replace the transformer if either of the input/output is
open or the transformer is damaged.
Check the voltage on display board. Replace the display board if it
is +5V else replace the main PCB.
Check the voltage of battery. Replace batteries if the voltage is
lower than 2.3V.
Check voltage. Call an electrician if not within limits.
Test capacitor.
Replace if not within +/-10% of manufacture's rating.
Check bearings. Replace the motor if the blower wheel cannot
rotate freely.
Pay attention to any change from high speed to low speed.
Replace the motor if the speed does not change.
The amount of the refrigerant is too much, making the compressor
load too big. Recycle and recharge the refrigerant after checking
for the reason.
The compressor is blocked inside. Replace after checking for the
reason.
Check voltage at electrical outlet. Correct if none.
Check and correct if water alarm happens.
Check voltage at the power cord terminal on Main PCB. Replace
the power cord if none.
Check resistance between the two input/output lines on
transformer. Replace the transformer if either of the input/output is
open or the transformer is damaged.
Connect wire. Refer to wiring diagram for terminal identification.
Repair or replace loose terminal.
Select fan speed and Check the voltage on main PCB. Replace
the main PCB if no voltage in anyone.
Test capacitor.
Replace if not within +/-10% of manufacture's rating. Replace if
shorted, open or damaged.
Fan blower hitting scroll. Realign assembly.
Check fan motor bearings. Replace the motor if motor shaft do not
rotate.
