  • error codes due to faulty components

Why Does My Frigidaire Air Conditioner Keep Beeping?

The remote control of your Frigidaire air conditioner functions as a small portable thermostat. It controls the air conditioner’s temperature and cycles.

This requires the remote to maintain a constant wireless connection with the air conditioner and notify you of the connection status through beeps. It will beep when it gets disconnected with your Frigidaire air conditioner, and it will beep again once it reestablishes connection with the air conditioner.

When the remote control becomes inactive for three minutes or more, it will beep to inform you that it is releasing control of the air conditioner. It will then beep when you press a button on the remote while it is in this status.

Remote Losing Power

One common reason for the beeping sound is a battery that is running low. Since the Frigidaire air conditioner’s remote control needs to maintain a connection with the air conditioner unit, it will alert you if its battery is about to die out.

Luckily, this is an issue that is easy to fix. Just replace the batteries with fresh ones, and you’re good to go. The battery you need depends on the model that you have.

Airflow Issue

Your Frigidaire air conditioner will inform you through beeps when the airflow becomes less than optimum. This could be caused by a blockage on any of the air conditioner’s airflow ducts—a common issue for window-type air conditioners.

Check the air pathways for anything that might be limiting the airflow. Leaves, bird’s nests, twigs, and other debris can block the airflow. Clear away the blockage to fix the air blockage issue.

Clogged filters

Dust and dirt can clog your Frigidaire air conditioner’s filters. Your air conditioner will notify you of this issue through a beeping sound.

Clean the filters thoroughly to fix this issue.

Additionally, some models would also beep when it is time to replace the air filters on your Frigidaire air conditioner. Normally, air filters should be replaced after every 250 hours of using your unit.

Just replace the air filter, and it should keep your air conditioner happy and silent for a while.

Error Codes

There are a couple of situations where a code accompanies the beeping of your Frigidaire air conditioner on the display panel. Depending on the model and exact issue, you might see an “ES” or “AS” on the display panel of your unit, along with the beeping sound.

When this happens, contact an air conditioner professional or an HVAC expert to verify the issue and fix it for you. These codes mean that a sensor inside your Frigidaire air conditioner is failing or has failed already.

Control board issue

Heavy use can cause the control boards of Frigidaire air conditioners to overheat and get fried. Fluctuations in electrical current, power surges, or issues in the cycling of electrical currents can also damage the control board.

Beeping—and refusing to turn on—often means that the control board is fried. The good news about this issue is that a replacement control board can easily be bought, and a tech-savvy family member can replace it. Have a professional replace the control board for you if you’re not comfortable with opening your Frigidaire air conditioner.

Electrical issue

The Frigidaire air conditioner will give you a beeping warning when it is not receiving enough power to operate normally—or it is not getting any power at all.

Reset the circuit breaker that supplies power to your air conditioner to get rid of the problem. If you’re getting this issue quite often, it might be time to connect your Frigidaire air conditioner to a dedicated power supply. This will prevent the circuit breaker from tripping because air conditioners generally consume a lot of electricity.

Let’s discuss the electrical issues that you could encounter with your Frigidaire air conditioner a bit more.

Power Fluctuations

Power fluctuations can cause your Frigidaire air conditioner to go into a protected mode and then beep non-stop. This can also happen when you turn it on and off quickly, thus confusing its electrical circuits into thinking that there is a problem with your power supply.

Safety Feature - Delayed Start

Frigidaire air conditioners have a built-in safety feature to help avoid tripping the circuit breaker in your home. When this safety feature kicks in, it will delay the start of the unit and wait for three minutes. This is to protect the electrical components of your Frigidaire air conditioner from damage that electrical fluctuations can bring about.

How to reset a Frigidaire air conditioner?

You can reset your Frigidaire air conditioner if it goes beyond the three-minute wait time and it is still not starting.

  1. The first thing to do is to unplug your unit from the wall socket.
  2. Press and hold down the reset button for 3-5 seconds.
  3. Plug your Frigidaire air conditioner back in.
  4. Turn it back on. It should complete the power-up cycle this time.

If it fails to power up after resetting it, do the same steps above but this time, hold the reset button for five seconds or more.

If it still fails to power up after holding the reset button longer, that means it has a more advanced problem that should be handled by a professional.

Troubleshooting common Frigidaire air conditioner problems

Here are some of the common issues that owners of Frigidaire air conditioners might encounter.

Air conditioner not cooling

Give your Frigidaire air conditioner an hour to start cooling if it is newly installed.

Another thing to check is whether the room temperature is higher than 62 degrees Fahrenheit or 17 degrees Celsius. Make sure that the temperature sensor is not touching or resting against the cold coil located just behind the air filter.

If you’ve just changed modes or settings, wait for three minutes for the compressor to turn on and start running again.

Ice on the cooling coil

This issue often happens on window-type units. Ice can form on the cooling coil if the outdoor temperature is colder than 62 degrees Fahrenheit or 17 degrees Celsius.

Defrost your Frigidaire air conditioner by putting it on fan-only mode.

One more thing you need to check is your air filter. A dirty air filter can cause ice to form on the cooling coil because the air inside the unit is unable to circulate properly. Clean or replace the air filter to resolve this issue.

AC is running but not cooling

Is your Frigidaire air conditioner running but not cooling the room? This is another possible air filter problem.

  • Check if the air filter is dirty or damaged. Clean or replace it as needed.
  • Check the louvers and make sure that they are in the right position to effectively cool the air. Your unit will have difficulty cooling the air if there is inefficient air distribution. For example, the louvers are facing a wall.
  • Make sure that the front of your air conditioner is not blocked in any way. Window curtains can get blown towards your unit and cover the front. This can limit airflow and hamper your air conditioner’s ability to cool.

Unresponsive remote control

The remote control has a maximum range of 20 feet or six meters. It might no longer work beyond this distance. Additionally, it can only send signals to your air conditioner within a front angle of 120 degrees.

Low batteries will also weaken the signal of the remote control and cause it to fail to connect to your unit.


The Frigidaire air conditioner has several beeping codes that help it communicate with its users. Understanding the meaning behind these beeps helps make it easier to use and maintain the Frigidaire air conditioner.
