GD Midea Refrigerant Equipment Co. Ltd Service manual for Electrolux split Series

PROBLEM CAUSE

REMEDY

Outdoor transformer

failure

Replace if failure.

Indoor PCB failure

Replace the PCB if the photon coupling on indoor PCB is failure.

Insufficient

cooling or

heating.

Indoor PCB failure

Replace after checked failure.

Lack of refrigerant

Check leakage. Recycle the refrigerant. Correct and recharge if there is

any leakage in the refrigerant system.

Soft starter module

failure

Check the module and the capacitor connected to the module. Replace

if failure.

Overcurrent protector

failure

Check the resistance of compressor overcurrent protector. Replace if

failure.

Compressor

protection

Outdoor PCB failure

Replace after checked failure.

Temperature sensor

failure

Replace after checked failure.

Connector failure or

loose

Repair or replace the sensor.

Open or short

circuit of outdoor

temperature

sensor

Outdoor PCB failure

Replace after checked failure.

Temperature sensor

failure

Replace after checked failure.

Connector failure or

loose

Repair or replace the sensor.

Room temp or

evap temp

sensor open or

short circuit

Indoor PCB failure

Replace after checked failure.

Soft starter module

failure

Check the module and the capacitor connected to the module. Replace

if failure.

Over load or too

low voltage

protection

Power failure

Wait if checked the power voltage is really too low.

Wiring failure

Correct if indoor fan motor wiring is loose.

Indoor fan motor

failure

Check the input of fan motor. Replace if failure.

Fan speed

beyond control

Indoor PCB failure

Replace after checked failure.

Zero-crossing

error

Indoor PCB failure

Replace after checked failure.

LED failure

Replace the display if checked failure.

No display on

indoor unit.

Remote control shut

the display

Push the button to turn the display on.

No power

Check the voltage. Call an electrician if not within the limit.

Wiring

Check the terminals. Repair and correct if loose.

Temperature setting

Check and adjust the temperature setting.

Mode setting

Check and adjust the mode setting.

Soft starter module

failure

Check the module and the capacitor connected to the module. Replace

if failure.

Reverse valve

solenoid coil

Check the reverse valve solenoid coil. Replace the coil if short, open or

damaged.

No cooling or

heating.

Reverse valve

If the reverse valve is blocked, the heating mode will not perform.

Replace the reverse valve after checking the reason.
