Blinking lights on your air conditioner are usually a sign that there’s a problem with your AC unit. There are several reasons why your AC light may start blinking, but the good news is that many of them are easy to fix.
Here are some of the most common reasons why your system may show your AC light blinking, as well as the best practices to make sure your air conditioner functions properly.
Why do AC units blink?
You may be asking yourself, “Why is my ac light blinking?” We’re here to help! AC units are programmed to display a blinking light whenever they run into an issue or begin to malfunction.
Even if the issue is small, the system is designed to “report” problems as soon as they are discovered by displaying the AC light blinking. The blinking light is your AC unit’s way of letting you know that something isn’t quite right.
Once you see your air conditioner light blinking, the next step is figuring out what the underlying problem is.
Possible reasons why your AC may be blinking
Problem: Electrical
One of the most common reasons that AC units show a blinking light is that there are electrical problems. This could be because there is irregular power drawing or loading, and the printed circuit board or electrical wiring is experiencing some issues.
Solution 1:
The first thing you should try is resetting your AC unit’s power switch. This could help sort out any problems, especially if the issue is the result of a power surge.
Solution 2:
If Solution 1 doesn’t work, the next thing to do is to hire a professional to assess the extent of the electrical issues. This is not a problem that you should attempt to fix on your own, given the high possibility of danger or electrocution.
Your technician will be able to perform isolation testing and other tests to determine the root cause of the problem. They will then be able to recommend the next steps to take or the necessary parts that you may need to order to fix the problem.
Problem: Filter issues
Another potential reason for your AC light flashing is that your filter may be installed incorrectly or may be clogged. If the filter is clogged with dirt, your AC unit will struggle to produce clean air and won’t be able to cool the air as effectively. This can cause a number of issues, including water leakages.
Solution:
Check the filter for your air conditioner regularly. Most air filters should be replaced every six to 12 months. Check to make sure the air filter is clean and also installed correctly. If you see any potential issues, take the steps to fix them. This may mean buying a replacement air filter.
Problem: Your unit needs maintenance
Your light may also be blinking because your air conditioning unit needs a regular check-up. AC units need check-ups just like people, especially if they’re a little older or have been working especially hard.
Solution:
Call a professional to come to check out your AC unit and make sure your unit is functioning properly and has everything it needs to run smoothly. They’ll be able to advise you on the next steps to take.
Problem: Your refrigerant levels are low
Your refrigerant levels may be low, causing your AC unit light to blink. All units have a required level of refrigerant, and they have a meter to measure how much is currently in the system. If your unit senses that your refrigerant levels have dipped below the recommended amount, the light will begin to blink.
Solution:
This is another problem that needs to be solved with the help of a professional. Refrigerant is a chemical that should only be handled by experienced technicians.
Problem: Your compressor is failing
AC units have parts called compressors that are essential to their function. If a compressor begins to fail, it is a problem that should be handled immediately. This is a common problem that happens during the summer. This is because air conditioners have to work extra hard during the hot months to create cold air. During this time, some parts of your unit may wear out more quickly than others.
To check if this is happening, look at the error codes presented by the unit. There should be a guide in your manual or online that can translate what each code means.
Solution:
Consult a professional if this is the problem with your AC unit. They’ll be able to replace all the missing parts and get your unit in top shape in no time.
Problem: Air circulation is poor
If your unit is struggling to circulate air through the room, it will show you the blinking status light to let you know there’s an issue.
This could happen if your unit is positioned poorly or for several other reasons. This is another instance where you should check the error codes to find out if that’s what’s troubling your unit.
Solution:
Call the manufacturer hotline or consult a professional technician to figure out how to fix an airflow problem with your AC unit.
Problem: Poorly installed unit
Your unit also may have been installed poorly. The light will also start blinking if this is the case, even if there are no problems within the unit itself. Believe it or not, it’s actually pretty easy to make a small error during installation that can cause problems down the line.
Solution:
Try adjusting the position of your unit to make sure it’s properly installed. You may want to call a professional to assist during this process.
Conclusion
If the light is blinking on your air conditioner unit, it probably means that there are issues that can be easily fixed within the unit but that need to be addressed. If the problem persists, contact us at AHWA and we will send a professional your way to get your AC up and running in no time.
