While the above paragraph may be confusing for most layman, we will break down the troubleshooting method for you here. Do note that this troubleshooting method is not in any ways sanctioned or authorized by Daikin. We used this method based on our experience in troubleshooting this Daikin error code. Firstly, we will check the heat exchanger at the condenser unit. If the heat exchanger appears to be dirty, we will propose to the customer to do Aircon chemical wash for the condenser first. We will then reset the unit to see if the fan coil unit is still blinking light or not. If there is still an error. We will then check the refrigerant level, if the level is too high, we will release some of the gas. If the issue still persist, it is likely the PCB or thermistor that is faulty.
