Samsung Inverter AC Light blink Error codes


When the light on a Samsung inverter AC is blinking, it indicates a specific issue or status. Here is a short description of some common blinking patterns and their meanings:

  1. Blinking slowly (1-second interval): This typically indicates that the AC unit is in standby mode and is waiting for a command from the remote control to start or change its operation.
  2. Blinking rapidly (0.5-second interval): This could indicate a communication error between the remote control and the AC unit. Ensure that the remote control is properly paired with the AC unit and try pressing any button to establish a connection.
  3. Blinking in a specific pattern (e.g., 2 blinks, pause, 2 blinks): Different blinking patterns can indicate various error codes or malfunctions. Consult the user manual or refer to the manufacturer’s website for a detailed list of error codes and their corresponding meanings. Alternatively, you can contact Samsung customer support for assistance.

It’s important to note that the exact blinking patterns and their meanings can vary depending on the specific model and series of the Samsung inverter AC. Always refer to the user manual or contact Samsung directly for accurate information related to your specific AC unit.
