Kelvinator AC Error Codes List and Solutions

The company offers its products through shops and retailers in almost every major city in the world, making sure it’s targeting the right consumers regardless of which part of the world they live in. offering top-of-the-line appliances that are designed to ensure effective and efficient working.

An error is not here to tell you it’s time to switch out your appliance, it’s a direct signal from the device – one that tells the owner something is wrong with the system that needs to be fixed. So rather than ignoring the error codes, your appliance is showing it’s time to note down the Kelvinator AC error code and get to the bottom of the problem.

When your energy supplier activates one of the 3 possible Demand Response modes, the display of the indoor unit will show d1, d2 or d2 as described below.

Codes Table

Error CodesMeaning
d1Compressor off
d2The air conditioner continues to cool or heat during the demand  response event,but the electrical energy consumed by the air conditioner in a half your period is not more than 50% of the total electrical energy that would be consumed if operating at the rated capacity in a half hour period.
d3The air conditioner continues to cool or heat during the demand response event, but the electrical energy consumed by the air conditioner in a half your period is not more than 75% of the total electrical energy that would be consumed if operating at the rated capacity in a half hour period.
E2Freeze Protection
E3Low pressure protection(refrigerant leak)
E4Discharge temperature protection
E5Overcurrent protection
E6Communication malfunction
E8Over-load protection

Care and Cleaning

Cleaning the Front Panel

Remove the front panel. Then wipe the front panel with a soft cloth moistened with water to remove any marks. Do not immerse the front panel into water so as to protect microcomputer components and circuit diagram on the front panel.

Cleaning the Air Filter (every 3 months)

Do not touch the fin of indoor unit during cleaning to avoid personal injury.

Check before Use

  1. Be sure that nothing obstructs the air outlet and inlet.
  2. Check if the batteries of remote control are installed.
  3. Check if the installation of the outdoor unit is damaged. If damaged, consult the installers.

Maintenance after Use

  1. Switch off the power supply.
  2. Clean the filter and bodies of indoor and outdoor units.
  3. Clear obstructions from the 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.

The unit does not operateThe 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 emittedSome 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.
Consult authorised service centre for cleaning if the odours persist.
Water flowing noiseThe swishing noise like water flowing is the refrigerant flowing inside the unit.
Mist is emitted in COOL modeDuring 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.
Cracking noiseThis 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 upIs the power cut off?
Is the power plug loose? (if applicable )
Is the circuit protection device tripped off?
Is voltage higher or lower? (Tested by professionals)
Is the TIMER correctly used?
Cooling/Heating effect is poorIs temperature setting appropriate? Is the inlet or outlet blocked? Is the filter dirty? Is the window or the door open? Is low fan speed set? Are there heat sources in the room?
Remote control does not transmit signalsCheck 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.
Is the remote control within its operating range or obstructed? Check the condition of the batteries and replace them if necessary.
Check if the remote control is damaged.
Water leakage of indoor unit1. The humidity is high. 2. Condensing water overflows. 3. Drain hose is loose or obstructed.
Water leakage of outdoor unitDuring cooling operation, water condensates 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 can not blow airIn 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 outletIf the unit operates at high humidity for a long time, moisture will be generated on the air outlet grill and then drip off.
H1-DefrostingIt is normal. The unit is in defrosting mode and heating will recommence soon.
E3-Low pressure warningYour air conditioner has lost refrigerant. Contact your installer to check for potential leaks.

  1. When I switch the in-wall unit on, it runs for a while, then switches on and shows an E1 code. It will always start again, for a while, the stop and show the code again. What is wrong ?

  2. hello, please i have a standing unit kelvinator that HMI screen is not displaying and only the lower part of the AC is cooling- the top window neither cooling nor blowing air at all….

    it is also observed that the indoor unit blower fan does not rotate during operation
