Reasons Why Your Aircon Unit Lights Are Blinking

What does a blinking aircon light mean?

When an aircon unit is not maintained regularly, the aircon unit will face issues and malfunction. Sometimes the blinking light is an indication that the aircon unit needs to undergo aircon servicing. You should try troubleshooting in case of clogged air filters or contact a professional aircon servicing company.

However, there could also be times when it simply means the system needs to be reset. When the system detects an overvoltage, it may be triggered into a self-protection shutdown mode, and consequently, a blinking light begins to flash. This is an automatic response to protect the unit from the increase in voltage.

But what could really be the reasons as to why these lights start to keep showing or blinking? Let’s take a look at some of the main reasons:

1) Low refrigerant levels

One of the reasons your aircon unit may be blinking is because of low refrigerant levels. This means that there isn’t enough coolant to keep your home at the desired temperature.

Pro 338 Reminder: Low refrigerant levels can result in refrigerant leaks and this could also be the reason why your aircon light is blinking. This needs to be fixed as soon as possible, as a leak can cause serious damage to your aircon unit.

2) Dirty filters

A clogged air filter can cause your aircon unit to blink. This is because the unit has to work harder to push air through the filter, which can overheat and damage the compressor. It is recommended that you replace your air filter every 3 months or so to prevent aircon blinking or any related aircon issues from happening.

3) Faulty wiring

If there is an aircon issue with the wiring in your aircon unit, it can cause the light to blink. This could be a fire hazard, so you will need to have a professional inspect the wiring and fix any issues.

Pro 338 Reminder: If the voltage in your home is too high or low, it can cause your aircon unit to turn on and off rapidly. This means that there is a bigger issue going on with your unit and you should contact an aircon professional immediately.

4) Malfunctioning compressor

If the compressor is not working correctly, it can cause a blinking light on your aircon unit. The compressor is responsible for cooling the air, so if it’s not working properly, your home will not be as cool as you want it to be.

5) Clogged condensate drains

If the drains that collect the water from your aircon unit are clogged, it can lead to water damage in your home. You will need to clean out the drains frequently to prevent this from happening.

6) Issues with the thermostat

If there is a problem with the thermostat, it can also cause your air conditioner’s light to blink. You may need to replace the thermostat if it is not working correctly.

7) Issues with system totals

Every aircon unit has multiple totals that add up together to determine if everything is working correctly or not things like bad airflow sensors. If there are any issues detected within these totals, the light will begin to blink as an alarm of sorts. A professional aircon technician could help troubleshoot this for you and provide more details on what needs attention on your specific aircon system.
