Gree Split Air Conditioner Troubleshooting


The air conditioner is not user serviceable.Incorrect repair may cause electric shock or fire so please contact an authorized service center for professional repair. Following checks prior to contact may save your time and money.

 The unit does not operate: The unit does not operate if it is turned on immediately after it is turned off. This is to protect the unit. You should wait about 3 minutes.

Odours are emitted: #Some odours may be emitted from the indoor unit. This is the result of room smells (such as furniture,tobacco,ect.) which have been taken into the air conditioner. #Consult authorized service center for cleaning if the odours still exist.

“Water flowing” noise: The swishing noise like water flowing is the refrigerant flowing inside the unit.

Mist is emitted in COOL mode: During cooling operation, a thin mist may be seen emitted from the indoor unit due to high room temperature and humidity. After a period of time, the mist will disappear with the decrease of room temperature and humidity.

Cracking noise: This is the sound of friction caused by expansion and/or contraction of panel or other parts due to the change of temperature.

The unit can not be started up: #Is the power cut off? #Is the circuit protection device tripped off? #Is voltage higher or lower? (Tested by professionals) #Is the TIMER correctly used?

Cooling/Heating effect is poor: #Is temperature setting appropriate? #Is the inlet or outlet blocked? #Is the filter dirty? #Is the window or the door open? #Is the low fan speed set? #Are there heat sources in the room?

Remote controller is not available: #Check if there is magnetic or electrical interference near the unit that may affecting operation of the controller. In this case, cut off the power supply as the air conditioner and reinsert it. #Is the remote controller within its operating range or obstructed? Check the condition of the batteries and replace them if necessary. #Check if the remote controller is damaged.

Water leakage of indoor unit : #The humidity is high. #Condensing water  overflows. #Drain hose is loose.




Water leakage of outdoor unit : #During cooling operation, water condensate is generated around the pipes and connection joints. #During defrosting operation,the thaw water flows out. #During heating operation,the water on the heat exchanger drips out.

Noise from indoor unit : #The noise emitted when the fan or compressor relay is switching on or off. #When the defrosting operation is started or stopped, there is a sound of refrigerant flowing in the reverse direction.

Indoor unit can not blow air: #In HEAT mode, when the temperature of indoor heat exchanger is very low, air flow is stopped in order to prevent cold air. (Within 2 minutes) #In HEAT mode, when the outdoor temperature is low or humidity is high, frost will be formed on the outdoor heat exchanger. The unit will defrost automatically and indoor unit will stop blowing air for 3-12 minutes. #During defrosting operation, water or vapour may be emitted. #In DRY mode, the indoor fan will stop blowing air for 3-12 minutes in order to avoid condensing water being vaporised again.

Moisture on air outlet : If the unit operates at high humidity for a long time, moisture will be generated on the air outlet grill and then drip off.

C5:Malfunction of connector jumper: Check if the connector jumper contacts properly. If the PCB is to be replaced, please take off the old for the new PCB.

F1:Malfunction of indoor ambient temperature sensor: Check if indoor room temperature sensor is connected properly.

F2:Malfunction of evaporator temperature sensor : Check if the evaporator temperature is connected properly.

H1:Defrosting : It is normal.

H6:Indoor fan block : #Check if terminal of the indoor motor is connected properly. #Replace the fan motor or the indoor board if disabled.

Buttons on the cover is unavailable or insensitive : Please check whether the cover is closed completely.

#There is harsh sound during operation, Power cord and power plug is overheating, Strong odours are emitted during operation, Water is leaking from the unit, The air switch or protection switch often trips, Water or other liquid is splashed into the unit : Stop operation and cut off the power supply.
