AC Light is Blinking

Why Your AC Light is Blinking: 5 Reasons Why


Air conditioners are complex electrical devices that are susceptible to the local climate. For instance, a buildup of debris and grit on the exterior grille might affect the overall operation of the air conditioner. Normally, a blinking air conditioning light indicates the need for air conditioning repair since the unit has likely recognised an internal fault. Several air conditioning companies have equipment with a flashing air conditioning light to indicate an internal fault requiring repair.

The following are five typical causes of a blinking light in air conditioners.

1. Inadequate Air Circulation

If your air conditioner cannot circulate air effectively, you may face a problem with it not being cold. For example, there might be a problem with the air conditioner’s drive motor or improper placement of the air conditioner itself. Examine the trouble code that your air conditioner is displaying, and then consult the user handbook.

2. Leaking Refrigerant

The refrigerant gas is an essential component of every air conditioner, as it is what maintains the unit’s efficiency and effectiveness. If an air conditioning machine lacks sufficient refrigerant, condensation may occur. This can lead to the condenser freezing, ultimately leading to the air conditioner leaking. In addition, a shortage of refrigerant leaks may cause damage to the compressor unit, resulting in a hissing sound.

3. Clogged-up Air Filters.

When the air conditioner’s filters are blocked, the evaporator unit can function normally, producing a great deal of strong, clean air. However, dust will build if an air conditioner is not properly maintained. This will render air conditioning filters vulnerable to clogging, which may result in odorous air conditioning. If you want to prevent airflow from becoming obstructed in your evaporator coil, clean the air conditioning filters at least once every three months. If you neglect your evaporator coils, they may freeze, which results in water leaks when the coil melts.

4. Frozen Evaporator Coils

The problem requires immediate attention when this alarm sounds since it may indicate that the air conditioner is leaking water. In addition, evaporator coils may potentially freeze due to problems within the ducting.

If you want to determine whether or not the evaporator fan coils are frozen, open the front panel of your unit and check to see if a film of ice has developed on them.

5. Inadequate Maintenance

If an air conditioning machine is not consistently serviced, it may encounter problems or possibly break down. So, it is essential that you inspect it frequently to maintain its condition. Regular air conditioning maintenance may guarantee that the machine is always clean and produces cool air. Occasionally, the flashing light signals that your air conditioning machine needs maintenance. If your air filters become blocked, you can attempt troubleshooting. Therefore, contacting an air conditioning service company is always an option.
