Kelvinator KSV26CRC Air Conditioner Troubleshooting

ProblemCause
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 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 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 up• Is 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 poor• Is 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 signals• 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.
• 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 outdoor unit• During 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 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 unitwill 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.
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.

ProblemPossible CausesWhat To Do M
Air conditioner does not start■ The air conditioner is unplugged.• Make sure the air conditioner plug is pushed completely into the outlet and switched on.
■ The fuse is blown/circuit breaker is tripped.• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
■ Power failure.• If power failure occurs, switch off and disconnect /unplug the power cord. When power is restored, reconnect (plug in) the power cord, switch on the power and wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
Air conditioner does not cool as it should■ Airflow is restricted.• Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
■ The air filter is dirty.• Clean the filter at least every 2 weeks.
■ The room may have been hot.• When the air conditioner is first turned on you need to allow time for the room to cool down.
■ Cold air is escaping.• Check for open furnace floor registers and cold air returns.
■ Cooling coils have iced up.• Set the air conditioner's vent to the closed position.
Air conditioner freezing up■ Ice blocks the air flow and stops the air conditioner from cooling the room.• Set the fan at MED or HIGH until the ice melts.

SymptomCause
Operation is delayed after restartTo prevent blowout of the fuse, the compressor will not operate while the protection circuit is working for about 3 minutes after sudden OFF/ON operation of the power supply, this is normal operation and designed to protect the compressor.
Fan speed changes from off, to very slow and then normalAutomatically happens in heating mode :
• prevents cold air blowing onto occupants when the heating operation is start,
• perform automatic defrosting operation,
• perform low temperature heating operation
Heating operation stops suddenly and defrost-light blinksIn HEAT mode, the indoor unit temporarily stops for maximum of 10 minutes to perform the automatic defrosting operation.
Mist coming out of the indoor unitIn COOL mode, a mist generated by condensation formed with sudden cooling process may be emitted.
Mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting
Low volume sounds are emitted by the air conditionerHissing sound - during operation or immediately after stopping the air conditioner, refrigerant flowing sound may be head.
Squeaking sound- normal expansion and contraction of plastic and metal parts caused by temperature change during the operation.
Rushing air- when louver resets its position.
Dust discharges from the unitMay occur when air conditioner is used for the first time or has not been used for a long time.
Emits a peculiar odourVarious smells generated from interior textile, furniture, or cigarette smoke absorbed into the air conditioner may be emitted. If not the case call an authorised service contractor.
Changes to fan only while cooling or heating modeRoom temperature reaches the temperature setting of the remote control. If not the case call your suitable contractor.
Operation is erratic, unpredictable or unresponsiveInterference from cell phone towers and remote boosters may cause the unit to malfunction
Disconnect the power and then re-connect.
Press the ON/OFF button on the remote controller to restart operation.
