If your Panasonic inverter AC is malfunctioning, you might notice that some indoor units do not have a display screen. Instead, they use 2 to 3 blinking LED lights to indicate errors. However, you can still find out the exact error code using the AC remote control. Let’s go through the steps to check the Panasonic AC errors and understand their meaning.
Finding Panasonic AC Error Code Using Remote
To check the error code, first, ensure that the time display on the remote control is not blinking. If it is, press the “Clock” button to stop it. Also, make sure your remote is in the “ON” mode before proceeding.
Now, locate the “Check” button on your remote control. Press and hold this button for 5 to 10 seconds using a pen or pencil until the display goes blank and shows two dashes (–). Next, use the “Up” and “Down” arrow keys in the Timer section to scroll through the error codes. Keep pressing the keys until you hear a beep sound from the remote. The number displayed at the time of the beep is your AC’s error code.
