An inverter AC is a type of air conditioner that uses a variable-speed compressor to adjust the cooling capacity according to the room temperature and demand. This makes it more energy-efficient, cost-effective, quiet, and comfortable than a normal AC. However, an inverter AC can also encounter some problems that can affect its performance and operation.
Here are some tips on how to troubleshoot your inverter AC.
Check the Power Supply
The first thing you should do when your inverter AC is not working properly is to check the power supply. Make sure that the power cord is plugged in securely and that the outlet is not damaged or tripped. You can also check the fuse or circuit breaker that controls the power supply to your inverter AC. If the fuse is blown or the breaker is tripped, you need to replace the fuse or reset the breaker. If the power supply is fine, you can move on to the next step.
Check the Remote Control
The remote control is another possible source of trouble for your inverter AC. Sometimes, the remote control may not be working due to low batteries, faulty buttons, or interference from other devices. You can try to replace the batteries, clean the buttons, or move away from any sources of interference. You can also check if the remote control is sending signals to the inverter AC by pointing it at a camera or a smartphone and pressing any button. If you see a flashing light on the screen, it means that the remote control is working. If not, you may need to replace or repair the remote control.
Check the Air Filter
The air filter is an important component of your inverter AC that helps to remove dust, pollen, bacteria, and other pollutants from the air. A dirty or clogged air filter can reduce the airflow and efficiency of your inverter AC, as well as cause health issues. Therefore, you should clean or replace your air filter every month or two during the cooling season. You can check your user manual for the specific instructions on how to access and clean or replace your air filter.
Check the Coils and Fins
The coils and fins are another vital part of your inverter AC that help to transfer heat between the refrigerant and the air. Over time, they can collect dirt, dust, debris, and mold that can impair their performance and cause corrosion. Therefore, you should clean your coils and fins at least once a year, preferably before the start of the cooling season. You can use a soft brush, a vacuum cleaner, or a coil cleaner spray to gently remove the dirt from the coils and fins. Be careful not to bend or damage the fins, as they are very delicate. You can use a fin comb tool to straighten them if needed.
Check the Refrigerant Level
The refrigerant is the substance that circulates in your inverter AC and absorbs and releases heat. It is essential for the cooling process of your inverter AC. If your refrigerant level is too low or too high, it can affect the efficiency and performance of your inverter AC, as well as cause damage to the compressor and other parts. Therefore, you should check your refrigerant level at least once a year, preferably by a professional technician. You can also look for signs of refrigerant leakage, such as ice formation on the coils, hissing or bubbling noises, or reduced cooling capacity.
Check for Error Codes
Some models of inverter ACs have a display panel that shows error codes when there is a problem with the system. These error codes can help you identify and diagnose the cause of the problem and suggest possible solutions. You can check your user manual for a list of error codes and their meanings. Some common error codes are:
– E1: Communication failure between indoor and outdoor units
– E2: Zero-crossing signal error
– E3: Indoor fan speed error
– E4: Indoor room temperature sensor error
– E5: Outdoor unit temperature sensor error
– E6: Compressor start-up error
– E7: DC fan motor error
– E8: Over-current protection
– E9: Low-voltage protection
– EA: High-voltage protection
If you see any of these error codes on your display panel, you should follow the instructions given in your user manual or contact a professional technician for assistance.

Conclusion
An inverter AC is a great device that can provide you with many benefits over a normal AC, such as energy savings, cost savings, noise reduction, and comfort improvement. However, an inverter AC can also encounter some problems that can affect its performance and operation. By following these tips on how to troubleshoot your inverter AC, you can fix some common issues by yourself or know when to call for professional help.
