Power supply
to the indoor
fan is
abnormal.
Check the power supply
to the indoor fan.
Remove the terminals
of the fan, and check
whether the voltage
between the 0 V and 48
V terminal is 48 V
using a multimeter. If
the voltage differs too
much, the power supply
is abnormal.
If the power supply
is normal, the indoor
fan is faulty.
Replace it by
following
instructions in
Replacing an
Indoor Fan
in the
air conditioner user
manual, and check
whether the
abnormality
disappears.
If the power supply
is abnormal:
1.
Check whether
the QF4 switch
on the power
subrack is turned
on. If yes, go to
the next step.
2.
Open the front
door, and check
whether the fan
fuse at the
bottom is blown
(fuses
FU9-FU16 from
the top to the
bottom are for
fans 1-8
respectively). If
a fuse is blown,
replace it.

Water overflows.
The drainpipe
