During cooling and drying
operation, compressor will
stop while indoor fan will
operate. During heating
operation, the complete unit
will stop operation.
1. Measure the voltage of
position L and N on wiring
board (XT), if the voltage
is high than 265VAC, turn
on the unit after the supply
voltage is increased to the
normal range; 2. If the AC
input is normal, measure
the voltage of electrolytic
capacitor C on control
panel (AP1), if its normal,
theres malfunction for the
circuit, please replace the
control panel (AP1)
