GD Midea Refrigerant Equipment Co. Ltd Service manual for Electrolux split Series
25
PROBLEM CAUSE
REMEDY
Air filter
Clean or replace if restricted.
Unit undersized
Determine if the unit is properly sized for the area to be cooled or
heated.
Condenser and
Evaporator
Clean or replace if restricted.
Room structure
Take proper measures to make the door and windows sealed well if gap
is found.
Air flow
Clean or remove if any barrier is found to block the inlet/outlet wind flow
of the unit.
Sunlight
Add a awning if the outdoor unit is exposed to the sunlight.
Outdoor fan motor
Check the fan capacitor on outdoor power control board and replace the
board if not /-10% of manufacturer's rating. Replace the motor if
the speed is not /-10% of manufacturer's rating but not because
of the capacitor.
indoor fan motor
For electrical function 2.3 models. Check the fan capacitor in indoor
electric box (for some models, the capacitor is on main PCB.) and
replace the capacitor (or main PCB) if not /-10% of
manufacturer's rating.
Replace the motor if the speed is not /-10% of manufacturer's
rating but not because of the capacitor.
Less refrigerant
Check the tubes for reasons of leakage. Recycle the refrigerant, correct
the leakage points and recharge.
Capillary tube
Regulate the flow if capillary tube is blocked. Make the evaporating
temperature appropriate if the evaporator is frosted.
Compressor
The inlet and outlet valve of the compressor is damaged, making the low
pressure connected with the high pressure. The refrigerating system is
difficult to produce high pressure and low pressure. Replace the
compressor after checking for the reason.
Insufficient
cooling or
heating.
Heat sources
Reduce if over loaded.
Water drainage failure Check the drainage pipe and repair if failure.
The indoor unit is
incorrect installed
Correct the installation if not correct.
Drainage pipe
blocked
Correct it.
Water drops from
indoor unit
The humidity in room
is too high
It's normal if the humidity in the room is over 85%.
Wiring failure
Check wiring. Correct if wrong wiring or loosen.
Wire EMC
Check wiring. Correct if the commucication wire is not shielded wire or
twisted with other wires.
Zero-crossing
error
Outdoor PCB failure
Replace if the LED is not on.
