Air conditioners stand out as efficient cooling devices, essential during scorching summer days. Similar to other appliances, after a period of use, air conditioners may encounter some basic malfunctions. However, you can troubleshoot these issues right at home without the need for technical assistance.
1. Air conditioner not functioning
Firstly, check if the power source of the air conditioner is on. If the air conditioner is turned on but the device is not operational, due to the scorching weather, many households continuously use air conditioners and other cooling devices, causing an electrical overload that triggers the circuit breaker to trip and the fuse to be damaged.
One of the reasons for this issue could be a depleted remote control battery. Check the condition of the remote control battery, and if it's depleted, replace it. If you have tried the above methods and still cannot fix the issue, contact the warranty center or a reputable repair facility for assistance.
2. Poor cooling from the air conditioner
This is one of the common issues often encountered after using an air conditioner for a period. Turn off the air conditioner and perform maintenance on the device. The reason for this situation is that the air conditioner fan blades, after a while, become dusty, sluggish, and clogged.
The solution is very simple. Remove the air conditioner's fan intake part, clean it thoroughly, and then reinstall it for the device to operate normally. Moreover, one of the factors leading to poor cooling is users not sealing windows tightly or the air conditioner's capacity being insufficient for a large room space.
3. Air conditioner automatically turns on and off frequently
The main cause of this phenomenon is the refrigerant pipes and the evaporator coil getting clogged with dirt, leading to blockages. Clean the machine to ensure it can operate normally or perform device maintenance.
In addition to that, overloaded power supply and a temperature sensor fault due to gas temperature can also cause the air conditioner to automatically turn on and off continuously. Therefore, users need to carefully check the causes to find an appropriate solution.
4. Air conditioner with loud noise
The loud noise from the operating air conditioner can be due to excess gas in the condenser, loose screws, or the compressor. In the case of excess gas, use an Allen wrench located at the end of the condenser to release some of the air conditioner's gas. Thoroughly check if the bolts or the compressor are damaged to address the issue of the air conditioner being noisy.
5. Air conditioner leaking water
The air conditioner is designed to continuously evaporate water to regulate the room temperature as desired by the user. Continuous water leakage from the air conditioner can cause damage such as floor peeling and cracking, resulting in expensive repair costs. Regularly clean the evaporator coil to adjust the drainage tube for stability and appropriate slope, facilitating easy water drainage.
6. Foul-smelling air blow
If the air blown from the evaporator coil has an unpleasant odor, the high probability is that your home's evaporator coil has leaked gas. Turn off the air conditioner, open the door to allow air circulation both outside and inside the room, and check if the gas trap is leaking.
Alternatively, the direct connection of the air conditioner's evaporator coil with the household sanitary water system is also a cause of the foul smell in the blown air. That's why you shouldn't place the sanitary water drainage pipe and the evaporator coil close together. Moreover, the reason could also be that you haven't used the air conditioner for a long time, allowing mold and bacteria to grow, resulting in a foul-smelling air blow from the evaporator coil.
7. Air conditioner alternates between cold and not cold
There are various reasons for this condition, including:
+ Incorrect control mode. The correct mode for the air conditioner is Auto or Cool. Check if the control mode on the air conditioner is correct. If it displays different modes, adjust it.
+ Faulty condenser fan. Spend 10 to 20 minutes checking if the condenser fan is damaged. If the fan is not running or rotating slowly, get it repaired immediately to ensure the stable operation of the air conditioner.
+ A malfunctioning air conditioner compressor is also one of the reasons for the device alternating between cold and not cold. Replace or repair the compressor to ensure the normal operation of the device.
+ Running out of refrigerant is another reason for this condition. Observe the condenser pipe and the connecting pipe carefully to determine the gas level and find timely solutions.
