Troubleshooting
Observe the liquid
loop sight glass.
The sight glass
is green.
If the sight glass completely
turns yellow, there is too much
water in the pipe. To solve the
problem, discharge refrigerant
from the pipe, vacuumize the
system, drain out water, and then
charge new refrigerant.
If the sight glass does not
obviously turn green, use a blow
drier to blow wind to the filter
until the sight glass turns green.
Wear working
gloves and touch
the compressor
angle valve, needle
valve, and
soldering points in
the cooling circuit
to check whether
there are oil stains.
There is no oil
stain.
Check whether the air suction and
exhaust pressure of the compressor
is within the normal ranges. If no,
contact Huawei technical support.
Check the pipes of
the humidifier
cylinder.
There is no
water stain
under pipes.
If drops of water are evenly
distributed, wipe off them with a
dry cloth.
If there are dense water stains,
identify the leakage point, close
the water inlet sluice, and repair
the leakage point.
Check the thermal
insulation foam.
The thermal
insulation
foam is
properly
wrapped.
Replace the thermal insulation foam
if it is damaged or missing. For
details, see
Check the indoor
fans.
The indoor fan
guards are not
misshapen, and
the fan blades
are intact.
Replace the fans by following
instructions in the air conditioner
user manual.
Fans are
working
properly.
Take out the foreign matter if the
fan is blocked.
Screws
securing the
fan are not
loose or
misshapen.
Tighten the screws using a 10#
socket wrench.
