Aircon Light Blinking – 7 Reasons And Troubleshooting Tips

Air conditioners are sophisticated electrical appliances that are vulnerable to environmental changes. The efficiency of an air conditioner can be diminished, for instance, if dust and debris have settled on the front filter.

The flashing of an air conditioner’s indicator light is usually a sign that the unit needs maintenance right away, as it indicates that the unit has recognised an internal fault. Numerous models of air conditioners feature an aircon light that flashes when an internal issue occurs, signalling the need for servicing. Here are several frequent causes of an air conditioner’s blinking light:

  • Electrical Problems:

The air conditioner’s status indicator light will turn on if it detects an abnormal load or power consumption. There may be a problem with the printed circuit board (PCB) or with the wiring. Isolation testing is the process to diagnose the problem and find a solution, and it should be performed by a qualified specialist.

The PCB or power cable should be replaced as soon as possible if there is a problem. It is possible that an electrical surge is to blame; to rule this out, try turning off and then back on the power to your air conditioning unit. In most modern homes, this switch can be found near the outdoor unit.

  • Low Refrigerant:

The lights could also be blinking because of limited refrigerant flow. It’s a warning mechanism in case the amount of refrigerant in the system drops below what’s needed for optimal performance. Since continued use will result in needless electricity consumption and could potentially harm the compressor, this needs to be addressed immediately.

A pressure test will reveal whether or not there is sufficient refrigerant, and any leaks should be repaired as adding more gas is only a temporary solution. In normal operations, there is no need to add more refrigerant because the system is closed-loop.

  • Inadequate Upkeep:

Problems and breakdowns are inevitable with an air conditioner that is not serviced routinely. This emphasises the significance of doing routine checks and maintenance. By keeping up with routine servicing, you can rest assured that your air conditioner will always produce clean, refreshing air.

The need for air conditioning maintenance may be indicated if the light of aircon keep blinking. If your air conditioner’s filters are blocked, you can either try cleaning them or call for professional service. Whatever the case may be, if you have any questions or concerns about your system, please give a call now. 

  • Filter Issues:

Your air conditioner’s flashing warning light could also be caused by a blocked filter or improperly placed filter. Your air conditioner’s efficiency and ability to clean the air will suffer if the filter is dirty. One of the problems that can arise from this is water leaks.

The solution is to routinely inspect the air conditioner’s filter. Typically, you should change your air filter every six to twelve months. It’s important to inspect the air filter to ensure it’s clean and that it’s been placed properly. If you find a problem, you need to do something about it. This could necessitate the purchase of a new air filter.

  • Compressor Failure:

Compressor failure is an emergency situation that requires rapid attention. This is a typical issue during the warmer months. This is because during the summer, when temperatures are high, air conditioners have to work harder to produce cool air. There may be a spike in the rate of wear for some components of your unit at this time.

The unit will display error codes if this is occurring, so you can check there. If you look in the handbook or online, you should be able to find a guide that explains what each code represents. If you suspect this may be the case with your air conditioner, it is recommended that you seek professional assistance. 

  • Poor Air Circulation:

If the air conditioner is having trouble distributing air throughout the room, the status light will flash. It could be due to a number of factors, including a bad location for your apartment. Here’s another time when error codes could help you figure out what’s wrong with your device.

If your AC isn’t blowing cold air, you should call the manufacturer’s support line or hire a professional technician to figure out what’s wrong.

  • Condenser Issue:

The condenser, which is positioned externally, dissipates the refrigerant’s excess heat. Light will blink if condenser is dusty and can’t cool correctly.

An alternative explanation is that the condenser fan has stopped spinning. Because the fan aids in cooling the condenser, its malfunction results in the condenser overheating and the indicator light flashing. Call a repairman over if you suspect either of these causes the issue.
