The Daikin E7 error code typically means a malfunction in the outdoor unit’s fan motor or the fan motor driver. To fix the error, you need a professional diagnosis from an aircon technician to figure out exactly what’s causing the E7 error. A compressor chemical wash (which starts at $80) can remove the blockage in the fan motor. But if parts are found to be defective, then the initial prices for replacing an outdoor fan motor and outdoor PCB are $280 and $250, respectively. All prices are dependent on which aircon model you are using.
A Daikin E7 error, put simply, means a transmission fault between the outdoor and indoor components of the air conditioning unit. This malfunction is typically caused by a defect in either the DC fan motor or fan motor driver of the outdoor unit. It can also be caused by a failure in the contact point of the fan motor connector. Either way, it is essentially a DC fan motor defect.
The remote that comes with your Daikin aircon unit has a display that normally reads the temperature levels. To get the Daikin error code to display (and to speed along the diagnostic and troubleshooting procedures), ensure that the Daikin remote is set for indoor control setting. Press the cancel button for the timer. Press for at least five seconds. Once you hear a long beep, the temperature display will change to display an error code that shows E7.
Since resolving a true E7 error can be costly and usually entails getting a qualified technician over to your house to replace the fan motor, a critical component of the outdoor aircon unit, be prepared to do your own basic troubleshooting first. If the error is just a glitch, it will simply go away after you’ve cleared the system by resetting it. To do this: turn off and then unplug the air conditioning unit. Wait for a few minutes, plug it back on and then restart. If it’s only a glitch, the E7 readout will no longer appear.
If a hard reset fails to clear the E7 error, switch the aircon off again and unplug it. Do a thorough visual check of the outdoor unit. Never touch any part of the outside unit while it is still connected to the power outlet. Once unplugged, take a look at the DC fan motor of the outside aircon unit; inspect it for any signs of damage, corrosion, or blockage. Check the wiring, if you are able, especially the network of wires between the fan motor and the PCB control board that is housed inside the outdoor aircon unit. There should be no loose connection or accumulated dirt and debris. If everything seems in order, plug the aircon back and restart it. Hopefully, this clears the E7 error.
The fix for a Daikin E7 fault, indicating potential trouble involving the outdoor fan motor of your air conditioning unit, might not be something that can be cobbled up at home and DIY-ed. Only a qualified service technician can properly remove a malfunctioning DC fan motor from your aircon’s outdoor unit and replace it with a working one. But before you contact Silverback Aircon through Whatsapp for a free consultation on your recurring Daikin E7 error issue, kindly note the indoor aircon unit’s model number first; you can find this number on the right-hand side of the fan coil. Otherwise, refer to the invoice for the condenser unit’s model number. Let us assist you in more efficiently diagnosing the problem with your aircon and give you a quote on the cost of fan motor repair and possible replacement.
