Why Is My Aircon Light Blinking?

Air conditioners are sophisticated electrical devices that are susceptible to environmental factors. For example, dust and debris on the outer grille can reduce the efficiency of your air conditioner. An aircon light blinking is typically an air conditioner repair sign since it occurs when the system detects an internal fault. Most air conditioning brands in Singapore have included the aircon light blinking system to signal an internal fault that necessitates aircon repair. Here are seven common causes for your aircon light blinking:

  1. Inadequate Air Circulation
You may encounter aircon not cooling if your air conditioning is unable to circulate effectively. This could be due to a problem with the air conditioning drive motor or incorrect air conditioner positioning. The user manual should be consulted to determine the problem code shown by the air conditioning. The majority of air conditioning manufacturers in Singapore have enabled error messages to be shown on the unit’s remote control or control panel display. If the error code isn’t listed in the user handbook, you might need to engage an air conditioner maintenance company in Singapore.
  1. Refrigerant leak
Refrigerant gas is a vital component of an air conditioner since it ensures that it functions properly. Condensation may form if there isn’t enough refrigerant, causing the condenser to freeze, resulting in water or gas spilling from your air conditioner. The compressor unit may be damaged as a result of the lack of refrigerant, and a hissing sound may be heard.
Low refrigerant levels are usually fixed by adding more air conditioning gas. The refrigerant leak will be repaired, as well as any other air conditioning concerns, by the professional aircon maintenance company in Singapore. Because refrigerant leaks are extremely dangerous to both your health and the environment, you should contact an air conditioner maintenance company as soon as you notice your air conditioner is leaking refrigerant.
  1. Clogged Air Filters
Clean air conditioner filters help the evaporator unit run more smoothly and produce more clean, powerful air. The aircon light may also blink if your air conditioner isn’t well-maintained. Hence, dust builds up, making your air conditioner filters clog and causing stink. Clean your air conditioner filters at least once every two or three months to avoid airflow restriction in the evaporator coil. The evaporator coils will freeze if they are neglected, resulting in water leaks when the coil melts. If thorough cleaning is required, it is advisable to contact a trained professional for aircon chemical overhaul.
  1. Frozen Evaporator Coils
If the aircon light blinks because of the frozen evaporator coils, it is important to pay attention right away because this could result in a water emergency due to leakage from aircon. A problem with the ducts could also produce frozen evaporator coils.
Open the front panel of your unit and look for a film of ice on the evaporator fan coils to discover whether they’ve frozen. If the evaporator coils in your air conditioner are frozen, the compressor may need to be turned off for a short time until the evaporator temperature rises. If the problem persists, you should contact an experienced aircon servicing company in Singapore.
  1. Improper Installation
If your air conditioner was not installed by professionals, the blinking aircon light could signal that the installation was improper. When this light displays, it’s critical to figure out what’s causing it by interpreting the problem code or referring to the manual handbook. To guarantee that your air conditioning installation is done correctly and runs well, we always recommend contacting an aircon installation professional in Singapore.
  1. Electrical Fault
A damaged PCB (printed circuit board) or electrical cable damage are two common causes of electrical issues in your air conditioner.
  • To start troubleshooting your aircon issue, look for the corresponding error number; it can help discover the root cause and direct your next steps.
  • Make sure the printed circuit board is in good shape. Flickering may occur if moisture or water is present on the PCB, causing the air conditioner compressor to malfunction.
  • If it’s clean, don’t get involved. If filth is discovered, gently clean it with a cotton cloth and alcohol.
  • Examine the electrical connections. If the unit is blowing air, the issue could be with the unit itself. Check for a blown fuse or component.
  • Check the electrical wiring protection components if the unit does not switch on. It’s possible that a fuse or breaker has blown. Also, make sure the ground wiring is in good working order, as it guards against transient surges.
However, if such an issue arises, it is always advisable to contact a professional air conditioning service company, as it is risky to deal with electrical as they will be equipped with the necessary technical knowledge and tools to resolve the problem.
