Poor Air Circulation
One possible reason for an aircon light blinking is poor air circulation. If your air conditioner is not getting enough air flow, it will cause the light to blink. This is because the air conditioner needs a certain amount of airflow to work properly. There are a few things that you can do to improve the airflow around your air conditioner.
- Make sure that there are no obstructions around the unit. Second, check the vents and make sure they are not blocked.
- Clean the filter. Poor airflow is often caused by a dirty filter, so making sure that your filter is clean is a good way to improve airflow.
- If you have an old unit, consider replacing it with a newer one that has better airflow.
Refrigerant Leak
An air conditioner that emits a blinking light is usually indicative of a refrigerant leak. In order to fix this issue, the root cause of the leak must be identified and repaired.
The first thing you need to do is identify the source of the leak. The most common places for leaks are at the connection points between the compressor, evaporator, and condenser coils. Once the source of the leak has been identified, you’ll need to repair it using a sealant designed for cooling systems.
Once the leak has been repaired, you’ll need to recharge the system with refrigerant. You can purchase a can of refrigerant at most auto parts stores. Be sure to follow the instructions on the can carefully, as too much or too little refrigerant can cause damage to your air conditioner.
Clogged Air Filters
A clogged air filter will restrict the flow of air, which can cause your air conditioner to overwork itself and eventually break down.
There are a few signs that you can watch out for that indicate that your air filter is clogged. If you notice any of the following, it’s time to clean your air filter:
- Reduced airflow from your vents: This is the most obvious sign that something is blocking the flow of air. If you notice that the airflow from your vents has diminished, it’s likely because your air filter is clogged.
- The air conditioner runs for longer periods of time: If your air conditioner has to run for longer periods of time in order to cool your home, it’s a sign that something is restricting the airflow. This increased run time will cause your energy bills to go up and can shorten the lifespan of your air conditioner
- Your home feels stuffy: A restricted airflow will make your home feel stuffy and stagnant. If you notice that the air in your home isn’t circulating well, it might be because of a clogged air filter.
If you notice that the air in your home isn’t circulating well, it might be because of a clogged air filter.
Luckily, cleaning your air filter is a fairly simple process. You’ll need to turn off your air conditioner and locate the filter.
The filter will either be located behind the front grille or in the return duct. Once you’ve located the filter, remove it and hold it up to a light source. If you can’t see any light shining through, it’s time to replace the filter.
However, if you can see light shining through, gently tap the filter on a flat surface to remove any dust or debris that might be clinging to it. Once the filter is clean, you can put it back in place and turn on your air conditioner.
Frozen Evaporator Coils
Your evaporator coils are responsible for absorbing heat from the air in your home. This process is what keeps your home cool and comfortable during the warmer months
However, evaporator coils can sometimes get too cold. When this happens, ice can form on the coils. As more ice builds up, it insulates the coil and prevents it from doing its job properly. This can cause your air conditioner to work less efficiently and ultimately lead to your air conditioner light blinking.
If you think that your evaporator coils might be frozen, there are a few things that you can do:
- Check your air filter and change it if it’s dirty. A dirty air filter can restrict airflow and cause your evaporator coils to freeze.
- Adjust your thermostat. If you have your thermostat set too low, it could be causing your evaporator coils to freeze. Try setting it to a higher temperature and see if that helps.
- Turn off your air conditioner for a few hours. This will give the ice on your evaporator coils a chance to melt.
- Call a professional. Sometimes, frozen evaporator coils can be a sign of a bigger problem with your air conditioner. If you’re not comfortable troubleshooting the problem yourself, call a professional for help.
Poor Maintenance
One of the most common reasons why air conditioners break down is because they haven’t been properly maintained. Just like any other appliance in your home, air conditioners need to be cleaned and serviced on a regular basis
If you don’t keep up with the maintenance of your air conditioner, it will start to show signs of wear and tear. Eventually, this can lead to bigger problems that are more expensive to fix.
To avoid costly repairs down the road, it’s important to keep up with the maintenance of your air conditioner. This includes regularly changing your air filter, cleaning your coils, and having your unit serviced by a professional.
