Water Drippage

• Water drips outside of the air conditioner while the appliance is running, and runs on the condenser to create a pinging noise. The pinging noise may be confused with a beeping sound, and is a normal sound that cannot be eliminated.
  
  

Remote Control

• The air conditioner's remote controls the cycle and temperature settings, and beeps when the signal is established or disconnected. A beep after three minutes of remote inactivity indicates the remote is no longer actively controlling the air conditioner, and beeps again once a button is pressed on the remote.
  
  

Faulty Sensor

• The sensor in the air conditioner regulates the appliance's thermostat setting, and may be defective if the air conditioner beeps during use. An error message appears below "Temp/Timer" when a problem is detected and simultaneously beeps depending on the error. Contact Frigidaire customer service at (800) 944-9044 to schedule a service appointment.
  
  

Compressor

• The high-efficiency compressor makes an audible, high-pitched noise while the air conditioner is in use and can be confused with a beeping sound. Older air conditioners do not have a high-efficiency compressor, but newer Frigidaire models include a powerful compressor to provide cooler air that emits noises near the front of the appliance.
