Error: The air conditioning does not work in Kaysun air-conditioning

How to eliminate the error “The air conditioning does not work.” in Kaysun air conditioning?

Error: The air conditioning does not work.

Description: Power failure.

Cause: The Kaysun air-conditioning unit is not receiving electrical power, or there has been a temporary power failure.

Solution: Wait for the power supply to be restored. Once power is available again, check whether the air-conditioning unit starts and operates normally.

If the electricity has been restored but the Kaysun air conditioner still does not work, check the controls and settings, as well as the unit’s general operating condition. If you cannot solve the problem, contact Kaysun technical service or a specialist in Kaysun air-conditioning repairs in your area.

Other operating problems related to Kaysun air-conditioning

Error: The unit turns on or off.

Error: The unit turns on or off.

Description: The system cycles on and off abnormally. This behavior is often related to incorrect refrigerant levels — either too much or too little.

Cause: Imbalanced refrigerant charge or leaks in the refrigerant circuit.

Solution: Check for refrigerant leaks and recharge the system with the correct amount of refrigerant gas according to the manufacturer’s specifications.

Frequent or abnormal cycling should not be ignored. The unit may start and stop repeatedly without providing stable operation, especially when the refrigerant charge is incorrect or the refrigerant circuit has a leak.

Error: It comes out of unit but does not cool.

Error: It comes out of unit but does not cool.

Description: The unit operates and air is emitted, but it fails to lower the room temperature effectively.

Cause: The temperature or operating mode may not be configured correctly. The problem can also be caused by airflow restrictions, dirty filters, or refrigerant issues.

Solution: Verify and configure the temperature and operating mode correctly. If the settings are correct, inspect the filters, airflow and refrigerant condition. Address any faults found by cleaning or replacing filters, fixing leaks and recharging refrigerant when necessary.

How to diagnose and fix these Kaysun air-conditioning problems

Check controls and settings

Ensure the thermostat or remote-control temperature and operating mode are set correctly. The cooling or automatic mode should be selected when cooling is required. Incorrect temperature or mode settings can cause poor cooling or frequent cycling, even when the unit is receiving power.

Inspect airflow and filters

Dirty or blocked filters and obstructed airflow reduce cooling efficiency and can cause the unit to cycle abnormally. Clean or replace the filters as necessary and remove any obstructions that restrict the movement of air through the indoor or outdoor unit.

After cleaning the filters and restoring proper airflow, check whether the Kaysun air conditioner cools correctly and whether it continues to turn on and off abnormally.

Evaluate the refrigerant

Low or excessive refrigerant will affect the operation of the air-conditioning system. Look for signs of leaks, such as oil stains or hissing sounds, and measure system pressures if you are qualified to do so.

An incorrect refrigerant level may cause the unit to cycle on and off abnormally or may allow air to come out of the unit without effectively cooling the room.

Repair leaks and recharge the system

If leaks are found, repair them and recharge the system with the correct refrigerant amount according to the manufacturer’s specifications. The refrigerant circuit should be checked carefully so that the cause of the loss is corrected before recharging.

Professional technicians can accurately diagnose refrigerant levels, detect hidden leaks and perform safe recharge and repairs.

Check the outdoor unit and fans

Ensure the outdoor condenser is clean and unobstructed. Also check that the fans and motors run properly. Restrictions around the outdoor unit or faults affecting the fans and motors can reduce cooling performance and contribute to abnormal operation.

Call qualified service when needed

If you cannot identify or safely fix the problem, contact Kaysun technical service or a specialized service. A qualified HVAC technician can diagnose the electrical supply, refrigerant circuit, airflow, filters, fans and other components of the system.

It is especially advisable to request professional assistance when the problem involves refrigerant leaks, refrigerant pressure or recharging with refrigerant gas. These tasks should be performed by qualified personnel using the correct amount and specifications for the equipment.

More tips

• If the electrical power has failed, wait for it to be restored before continuing with other checks.
• Verify the remote-control or thermostat temperature and operating mode before assuming that the unit has a technical fault.
• Clean or replace dirty filters and make sure that the airflow is not blocked.
• Keep the outdoor condenser clean and unobstructed, and check that the fans and motors run properly.
• Regular maintenance, including cleaning filters and checking refrigerant and airflow, helps prevent these errors and prolongs equipment life.
