20 Troubleshooting Kelvinator Air Conditioning
Troubleshooting
Problem Cause
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 compressor. Please wait for about 3 minutes before turning the unit on again.
Odours are emitted
Some odours may be emitted from the indoor unit. This is the result of room smells (such as
furniture, tobacco, etc) which have been taken into the unit.
Consult your authorised service centre for cleaning if the odours persist.
“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 as the room temperature
and humidity decrease.
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 cannot be started up
• Is the power cut off?
• Is the power plug loose?
• Is the circuit protection device tripped off?
• Is voltage higher or lower? (tested by professionals)
• Is the TIMER correctly used?
• Are the batteries exhausted?
Cooling/Heating effect is poor
• Is the temperature setting appropriate?
• Is the air inlet/outlet blocked?
• Is the filter dirty?
• Is the door or window open?
• Is low fan speed set?
• Are there heat sources in the room?
Water leakage of indoor unit
• The humidity is high.
• Condensing water overflows.
• Drain hose is loose or obstructed.
Water leakage of outdoor unit
• During cooling operation, water condenses around the pipes and connection joints.
• During defrosting operation, thawed water flows out.
• During heating operation, water on the heat exchanger drips out.
noise from indoor unit
• The noise emitted when the fan or compressor relay is switched on or off.
• When the defrosting operation is started or stopped, there is a sound of refrigerant flowing
in the reverse direction.
Indoor unit cannot blow air
• In HEAT mode, when the temperature of indoor heat exchanger is very low, airflow 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 and the indoor heat exchanger. The unit will defrost automatically and indoor unit
will stop blowing air for 2-3 minutes.
• During defrosting operation, water or vapour may be emitted.
• In DEHUMIDIfY mode, the indoor fan will stop blowing air for 3 to 12 minutes in order to avoid
condensing water being vapourised again.
Moisture on the air outlet
If the unit operates at high humidity for a long time, moisture may be generated on the air outlet
grill and then drip off.
H1 code: defrosting
This is normal. The unit is in defrosting operation and heating will recommence soon.
