Air Conditioner - Beeping
A window or built-in air conditioner may make a beeping sound. The following is an explanation of when you would expect the air conditioner to make a beeping sound.
It is normal for an air conditioner (window / built-in) to beep one time when:
-
The power cord is connected. All lights in the display are on and double "8s" will appear in the LED display for 2 seconds. If there is no other operation to press other buttons, lights are off.
-
-
If there is a power interruption or failure, all lights in the display will come on and double "8s" will appear in the LED display for 2 seconds when power is restored. Then, the air conditioner will run in the mode that ran before the power failure.
-
-
A button (including a remote control button) is pressed while power is on. The display light can be on or off.
When continued pressing of the "+/-" buttons to increase/decrease the temperature or time occurs, it will only beep once at the moment pressed.
The air conditioner will beep two times if:
-
A button press (including a remote control button) failed. The display light and/or double "8's" is not changed.
