Kelvinator Air Conditioner Error Code Solutions

Malfunction Code Table of Outdoor Unit

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

Problem: The unit does not operate

Cause: 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.

Problem: Odours are emitted

Cause:

1. 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 air conditioner.
2. Consult authorised service centre for cleaning if the odours persist.

Problem: “Water flowing” noise

Cause: The swishing noise like water flowing is the refrigerant flowing inside the unit.

Problem: Mist is emitted in COOL mode

Cause: 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 decrease of room temperature and humidity decreases.

Problem: Cracking noise

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

Problem: The unit can not be started up

Cause:

1. Is the power cut off?
2. Is the power plug loose? (if applicable )
3. Is the circuit protection device tripped off?
4. Is voltage higher or lower? (Tested by professionals)
5. Is the TIMER correctly used?

Problem: Cooling/Heating effect is poor

Cause:

1. Is temperature setting appropriate?
2. Is the inlet or outlet blocked?
3. Is the filter dirty?
4. Is the window or the door open?
5. Is low fan speed set?
6. Are there heat sources in the room?

Problem: Remote control does not transmit signals

Cause:

1. Check if there is magnetic or electrical interference near the unit that may affecting operation of the remote control. In this case, pull the plug out and reinsert it.
2. Is the remote control within its operating range or obstructed? Check the condition of the batteries and replace them if necessary.
3. Check if the remote control is damaged.

Problem: Water leakage of indoor unit

Cause:

1. The humidity is high.
2. Condensing water overflows.
3. Drain hose is loose or obstructed.

Problem: Water leakage of outdoor unit

Cause:

1. During cooling operation, water condensates around the pipes and connection joints.
2. During defrosting operation, thawed water flows out.
3. During heating operation, water on the heat exchanger drips out.

Problem: Noise from indoor unit.

Cause:

1. The noise emitted when the fan or compressor relay is switched on or off.
2. When the defrosting operation is started or stopped, there is a sound of refrigerant flowing in the reverse direction.

Problem: Indoor unit can not blow air

Cause:

1. 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)
2. 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.
3. During defrosting operation, water or vapour may be emitted.
4. In DRY mode, the indoor fan will stop blowing air for 3-12 minutes in order to avoid condensing water being vaporised again.

Problem: Moisture on air outlet

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

Problem: H1-Defrosting

Cause: It is normal. The unit is in defrosting mode and heating will recommence soon.

Problem: E3-Low pressure warning

Cause: Your air conditioner has lost refrigerant. Contact your installer to check for potential leaks.

The pressure in the refrigeration system is low and could result in the unit breaking down. Ask a certified installer to control it. If any one of the following situations occurs, immediately stop all operations, disconnect the power supply, and contact the authorised personnel.

• There is a harsh sound during operation.
• Strong odours are emitted during operation.
• Water is leaking from the unit.
• The circuit breaker often trips.
• Water or other liquid is splashed into the unit.
• Power cord and power plug is overheating.
