Beko air conditioner troubleshooting

Before you start repair works, you need to carry out a diagnosis to identify the problem. The same procedure will help you find out if the air conditioner has broken down completely or if there are other reasons why it stopped working – for example, because of a draft or lack of voltage.

IssuePossible Causes
Unit does not turn on when pressing ON/OFF buttonThe Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
The unit changes from COOL/HEAT mode to FAN modeThe unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
The indoor unit emits white mistIn humid regions, a large temperature difference between the room's air and the conditioned air can cause white mist.
Both the indoor and outdoor units emit white mistWhen the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
The indoor unit makes noisesA rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit's plastic parts.
Both the indoor unit and outdoor unit make noisesLow hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.
The outdoor unit makes noisesThe unit will make different sounds based on its current operating mode.
Dust is emitted from either the indoor or outdoor unitThe unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods of inactivity.
The unit emits a bad odorThe unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
The unit's filters have become moldy and should be cleaned.
The fan of the outdoor unit does not operateDuring operation, the fan speed is controlled to optimize product operation.
Operation is erratic, unpredictable, or unit is unresponsiveInterference from cell phone towers and remote boosters may cause the unit to malfunction.
In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
Temperature setting may be higher than ambient room temperatureLower the temperature setting
The heat exchanger on the indoor or outdoor unit is dirtyClean the affected heat exchanger
The air filter is dirtyRemove the filter and clean it according to instructions
The air inlet or outlet of either unit is blockedTurn the unit off, remove the obstruction and turn it back on
Doors and windows are openMake sure that all doors and windows are closed while operating the unit
Excessive heat is generated by sunlightClose windows and curtains during periods of high heat or bright sunshine
Too many sources of heat in the room (people, computers, electronics, etc.)Reduce amount of heat sources
Low refrigerant due to leak or long-term useCheck for leaks, re-seal if necessary and top off refrigerant
SILENCE function is activatedSILENCE function can lower product performance by reducing operating frequency. Turn off SILENCE function.

CaseExplanation
The air conditioner does not operate.• Have you made a mistake in timer operation?
• Has the fuse blown or has the circuit breaker been tripped?
The room has a peculiar odor.• Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room.
It seems that condensation is leaking from the air conditioner.• Condensation occurs when the airflow from the air conditioner cools the warm room air.
Air conditioner does not operate for about 3 minutes when restarted.• This is the protector of the mechanism.
• Wait about three minutes and operation will begin.
Does not cool or heat effectively.• Is the air filter dirty? See air filter cleaning instructions.
• Has the temperature been set incorrectly?
• Are the indoor unit's air inlet or outlet vents obstructed?
The air conditioner operation is noisy.• For a noise that sounds like water flowing. -This is the sound of freon flowing inside the air conditioner unit.
• For a noise that sounds like the compressed air releasing into atmosphere.
-This is the sound of the dehumidifying water being processed inside the air conditioning unit.
Remote control display is faint, or no display at all.• Are the batteries depleted?
• Are the batteries inserted in the opposite (+) and (-) directions?
Crack sound is heard.• This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.

ProblemPossible CausesI What To Do
Air conditioner does not start■ The air conditioner is unplugged.• Make sure the air conditioner plug is pushed completely into the outlet.
■ 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, turn the mode control to OFF.
When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
■ High voltage.• If the voltage is unusually very high or low the circuit Breaker will trip.
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.
