Air Conditioner Light Blinking: Reasons and Repair Tips

Air Conditioner Light Blinking: Reasons and Repair Tips

The air conditioner is an easy-to-use appliance with a complex mechanism designed to provide your desired temperature while improving the air quality. Because of its complexity, it can be hard to identify internal problems with your AC unit. If you happen to turn your air conditioner on and see a blinking light, it means that there are some issues within your unit.

The blinking light from your air conditioner is an indication that there is an internal issue with your unit. Some of these internal issues can be addressed with a quick fix, while others will require professional repairs. 

Here are some reasons why your AC light may blink and some solutions you can try.

Reasons Why an Air Conditioner Light is Blinking

Poor Air Circulation

Poor Air Circulation

Poor air circulation can be caused by many factors, like a dirty air filter, incorrect placement of the AC unit, or some problems with the motor. If there is poor circulation, your AC unit may have some difficulty cleaning the space. Clogging due to excess dirt can also affect other parts of the air conditioner, which may cause it to malfunction.

We highly encourage cleaning your air filters regularly to prevent clogging and poor air circulation. Regular maintenance services are also vital to ensure that all parts of your air conditioner are in good shape.

Frozen Evaporator Coils

Frozen Evaporator Coils

Liquid leaking from your air conditioner during the cooling process is not normal. This can be caused by frozen evaporator coils due to the weather, dirt buildup, or duct issues. The building of ice behind the front panel is an indication of evaporator coils that are freezing. This can affect other parts of the air conditioner.

Refrigerant Leaks

Refrigerant Leaks

The refrigerant is one of the most important parts of an air conditioner. If your refrigerant is leaking, your unit will have a refrigerant shortage, which may cause condensation. This can freeze the condenser and damage the compressor. You may identify this problem by hearing some hissing sounds from your air conditioner. 

Like frozen evaporator coils, refrigerant leaks should be professionally fixed to prevent further damage and possible health risks.

Electrical Problems

Electrical Problems

Electrical problems like irregular power loading, damaged PCB (Printed Circuit Board) or issues with the wiring can also cause your air conditioner light to blink. If the problem is due to a power surge, you may reset the power switch. If it doesn’t work, you will need to get professional help to identify and fix the problem.

Faulty Compressor

Faulty Compressor

Your air compressor is another vital part of your air conditioner. If you have a faulty air compressor, your whole unit will struggle to function. Since the air compressor goes through a great deal of wear and tear, make sure you give it the necessary maintenance that it needs.

Air compressor issues are generally costly to repair and replace. If you’re having some issues with your air compressor, try checking into your warranty since some manufacturers offer 3-5 years of warranty coverage for the air compressor.

Your Air Conditioner Lacks Maintenance

Lack of proper maintenance can result in the issues that we listed above. It can even be worse and may require you to go through pricey repairs or the replacement of your whole AC unit. To prevent these issues, it’s vital to undergo regular maintenance service. Aside from this, you may do some air conditioner cleaning at home to make sure that your air conditioner will just release fresh air.

Some major air conditioner issues call for expensive repairs. This includes major parts like the motor or compressor. If you’re wondering whether it’s good to push through expensive repairs or if it’s better to fully replace your unit, look into the age of your AC unit. cost and benefits of the repair. If your repair cost exceeds 50% of the cost of a new AC unit and you’re in doubt if you will no longer face some hassles afterward, buying a new energy saving air-con might be a better choice. If your air conditioner is already old enough to be replaced, it’s time for an upgrade.
