The Daikin E5 error code typically points to an overheated compressor. An overloaded compressor can either be from lack of maintenance or there’s an issue with the sensor (or the wiring) that reads the overload. To fix an E5 error, performing a compressor chemical wash (for an initial price of $80) might do it. If faulty aircon parts require replacement, you might need to shell out $150 for the Ev coil, $150 for the thermistor, $150 for the PCB, and $300 for the compressor itself. All initial prices are simply estimates and depend on which aircon model you are using.
Are your compressor Aircon lights blinking or not working? You may have found an Aircon technician and they mention to you that you have a Daikin E5 error code. What does it? Don’t worry, we are here to guide you about it. In this article we will address how to troubleshoot and fix this error code. We will also let you know what are some of the possible causes of the problem and how to solve it. We will also provide an estimated cost to solve this issue.

What is Daikin E5 Error Code?
Daikin E5 error code refers to Inverter compressor motor failure or overheat. When overload is detected on the compressor system, this error will be activated. Prompting the technician to check what is the root cause of the error. For Example, is the winding of the compressor faulty? Or could it be that the heat exchange is dirty, causing the compressor to overheat.
if you are facing Daikin E5 Error Code. The first step is to check whether the discharge pipe thermistor is disconnected or not. Sometimes it can just simply be a case of loose connection, and securing the thermistor can just solve the problem.
Secondly, if the thermistor is connected properly to the section. We will have to start measuring the resistance value of the thermistor. If the thermistor reading is abnormal, we can attempt to replace it first and see if it solves the problem. If the thermistor reading is normal.
Thirdly, we can then proceed to check on the connector S40 and Overload protector. If these 2 parts don’t seem to be abnormal.
Fourthly, we will then proceed to check on the Ev coil reading. If the ev coil is working perfectly fine.
Lastly, we will go on and check the refrigerant line and see if there is a smooth operation. If the refrigerant line is working fine, then the issue is most likely with the outdoor pcb or the compressor.
First things first, turn off the power to your air conditioner and wait for a few minutes before turning it back on. This simple reset may solve the issue and clear the error code.
If the error persists, as mentioned in the troubleshooting guide earlier. Thus, some of the parts that may need replacement which includes thermistor, Ev coil, PCB, and some connector. In the worst case scenario, the compressor will need to be replaced. However, it is extremely difficult to replace the compressor. So most technician will attempt to replace the whole condenser unit instead. Moreover, there is much lesser aftersales service with this service as well.
Furthermore, if the issue is due to dirty heat exchanger. Simply doing a compressor chemical wash will suffice.
Hence, to figure out the exact solution. One will have to do a lot of check to figure out the root cause of the problem. It’s advisable to reach out to a trained technician for further assistance. We can provide you with specific troubleshooting recommendations based on your unit’s model and age. Sometimes it could also be malfunctioning of the PCB that causes the compressor to overload.
The estimated cost as shown above is the estimated price for fixing a system 1 Daikin condenser unit. However, the price is generally more expensive when it comes to fixing a Daikin unit with bigger btu or a multi split Daikin Unit. Furthermore, fixing a VRV Daikin unit will be way more expensive than the price suggest above. As it may involves resetting of the unit.
