  If the operation lamp on your Daikin Air Conditioner is blinking, you should first perform the diagnostic procedure. Also, ensure all indoor units connected to a multi-system outdoor unit are set to the same operation mode. If they aren't, set all indoor units to the same operation mode and check if the operation lamp stops blinking. You can also try setting all indoor units to cooling or heating mode to see if the operation lamp returns to normal.

  If your Daikin Air Conditioner stops suddenly and the operation lamp blinks, it might be due to conflicting operation modes. Here's what you should do: * Check if all indoor units connected to the multi-system outdoor unit are set to the same operation mode. * If the operation modes are different, set all indoor units to the same mode and see if the blinking stops. * If the operation mode is set to automatic, try setting all indoor units to either cooling or heating and check if the operation lamp returns to normal.

  If the Daikin Air Conditioner operation stops suddenly and the operation lamp blinks, it might be due to an operation mode conflict. Ensure all indoor units connected to the multi-system outdoor unit are set to the same operation mode. If they aren't, change them to the same mode and see if the blinking stops. If the mode is set to automatic, try setting all indoor units to either cooling or heating and check again.

  The operation lamp on your Daikin Air Conditioner might be blinking because a protection device in either the indoor or outdoor unit has been activated, or the thermistor is malfunctioning. It could also indicate a signal transmission error between the indoor and outdoor units.
