Daikin is in the Air conditioning business for over 90 years now. They have a trusting customer base because they provide quality products.
However, recently, some users have been complaining about certain issues with the systems. These are common error codes that are already identified by the company and you can also find the solutions for them on the official support forums.
In this article, we will discuss the Daikin Error Code F3. This error code shows up when there is a fault in the discharge temperature sensor. The temperature of the system goes outside the acceptable range set by the company standards. This is when the system alerts you about the issue by displaying the error code F3.
We will discuss the solutions for the issue in the next section compiling user support suggestions as well as discussions on user forums. Let’s get into it.
How to get rid of Daikin Error code F3?
As we have pointed out above, the Daikin error code F3 indicates an issue with the discharge temperature sensor. It is a very crucial part of the air conditioning system and if you are facing this error this means that your system is displaying signs of less efficiency, and increased energy consumption. There is also a risk of long-term damage to the unit. Here is how you can get rid of the issue.
Fix 1: Power cycle the air conditioning system
Sometimes, the issue with the device does not have a deeper root cause and the only issue is a temporary glitch.
In these cases, restarting the system afresh helps with the same. To refresh the system properly, you can power cycle the system. Turn off the system, unplug it, wait for a few minutes, and then plug it back in. Turn on the system and the temporary glitches will be eliminated.
Fix 2: Check the discharge temperature sensor
The issue with the error code F3 is based on the malfunctioning of the discharge temperature sensor. It is a good idea to eliminate this issue the first chance you get. This will help you understand if the issue lies with the temperature sensor or if further attention to other issues is needed.
Check if the discharge temperature sensor is connected properly. If it is connected securely, the next step is to check if the sensor is damaged.
If you find that the sensor is damaged, you will need to get it replaced and we recommend going to a professional with it.
Fix 3: Check the wiring to the sensor as well as the entire system
The wiring is a very important part of any device that functions on elaborate electrical mechanisms. It is no surprise that the wiring is also an important element of the Daikin air conditioning system. Check if the device has secure wiring connections and that all the elements of the device are receiving electric input.
The sensor also needs to be given special attention in terms of wiring. Check if the sensors are receiving proper electrical input.
Also, check if there are any broken wires in the circuit. These broken wires need immediate replacing because they can not only be a problem for the device’s functioning but can also cause safety issues like fire hazards and electrocution risks.
Fix 4: Check the air filter and condenser coil
Apart from the solutions that are suggested by the official support team, there are also some suggestions that are suggested by the users themselves.
Some users have suggested that you should take a look at the air filter and the condenser coil for the system. The air filter needs to be cleaned at regular intervals especially, at every new season when you start using the system after a long break you need to clean out the air filter. If the air filter is blocked, it can cause the error code F3. Same with the condenser coil which also needs to get checked for obstructions.
Fix 5: Check the level of refrigerant in the system
There is a certain acceptable level of refrigerant in the system. The refrigerant needs to be above that level.
If the refrigerant level is below the threshold amount, you will face the error code F3. This might not be the reason for the error code F3 each time but it can certainly be a contributing factor.
If the level of refrigerant is down, you need to contact the maintenance team to get it to the optimum level before operating the system.
Fix 6: The airflow in the room should be checked out
The room that you are using the air conditioning in should have proper airflow. The air conditioning is surely responsible for maintaining the temperature of the room but the airflow in the room is not entirely up to the air conditioning device.
If the room is too warm or too cold, it can cause undue pressure on the air conditioning device. Make sure that the room has proper airflow and ventilation before turning on the device.
Fix 7: Take a look at the outdoor unit
The outdoor unit often gets clogged with debris and unwanted materials. This is why regular servicing of the device is necessary.
If you see the error code F3, check the outdoor unit for any debris collected, and then clean out all the filters and nooks of the outdoor unit.
Once you make sure that the outdoor unit is free of any obstructions, turn on the device.
Fix 8: Contact technical support
If you cannot figure out what is exactly wrong with the device even after a thorough examination and none of the above solutions have worked for you, it signals that there is a deeper issue with the system.
In this case, you should contact the technical support team or an electrical technician that you trust. Even in the solutions that we have suggested above, do not touch the wiring and internal parts of the device if you do not have any prior experience with handling electrical machinery.
The error code F3 on the Daikin Air conditioning systems is an issue that generally shows up due to a faulty discharge temperature sensor.
We have also mentioned other issues that can be a contributor to this issue. We hope that this helped you get rid of the error code and your system is now functioning efficiently.
