Is your Daikin in Brisbane not working or not running as efficiently as it should?
You can diagnose the problem yourself by using Daikin’s fault code finder!
Finding the fault via this process gives you a head start, so when you can contact an expert technician for aircon servicing, you can tell them the problem. While you might be able to diagnose the problem yourself, we discourage you from trying to fix the issue yourself, too.
By using this technique, you don’t have to fiddle around to explain or diagnose the error – which can also be very dangerous.
Today, Tri-Tech’s air conditioning specialists explain exactly how to use the fault finder with your Daikin remote to find the source of your problem.
Please note that while these instructions may be applicable to many Daikin units, they may not be suitable for your particular unit. If you’re still experiencing issues, please get in touch with us – we’d love to assist.
How do I find my Daikin fault code?
To find the source of your AC issue, hold down the “Cancel” button on your remote while pointing it to your indoor unit for about 5 seconds until the screen on your remote says “00”.
Once this appears, keep clicking cancel and different codes will appear on the screen.
There will be a beep at each button click, and once you approach the correct fault code there will be a much longer, significant beep.
The code that accompanies this is your error code. This code will either be two letters, two digits, or most commonly, a letter followed by a digit.
Why is my Daikin mini split blinking?
There are three small lights on a Daikin split unit. The top light will turn green when you turn the system on, and this same light will flash when there’s something wrong with it.
The middle light will appear when you turn on the timer, and the bottom light will appear when you turn on the sensor.
What do these fault codes stand for?
There are various faults that air conditioning in Brisbane can have.
If the fault code starts with an A or a C, this means the problem lies within the indoor unit – the AC you see mounted on your wall.
If the code starts with: E, F, J, K, L, P, or X, then there is an error with the outdoor unit.
If the code starts with a U or an M, then there is an issue with the actual system, which could be related to:
- Power supply
- The printed circuit board – or PCB
- Transmission errors
- Communication errors between parts, such as the outdoor and indoor units
If the code starts with a number, then there is an uncategorised or miscellaneous error that doesn’t fit into the other three categories, such errors include:
- The ozone density being abnormal
- A malfunction of transmission between the heat reclaim ventilator ( the dust collection unit) and the fan unit
- A malfunction of the heat reclaim ventilator
- The door switch is open
- The hot water temperature is too high
What does F0 error code mean?
You can look at the various error codes and what they indicate here.
However, F0 isn’t on this chart even though it is a common error that appears on these remotes.
F0 indicates that there is insufficient refrigerant in your system. Refrigerant is a chemical gas that absorbs heat as well as transfers cool air to your various indoor units.
If you’re low on refrigerant, then you need to contact our air conditioning experts and schedule a Daikin service.
How do I assess problems with my ducted Mitsubishi air conditioning?
This code finder system is found on most Daikin split systems.
For faulty ducted air conditioning in Brisbane or for a Mitsubishi aircon, you should contact an air conditioning specialist like Tri-Tech to assess your problem and provide the most efficient and cost-effective solution.
No matter what air conditioning you have, you should clean your filters twice a year. This can help prevent a multitude of faults that can come about from the domino effect of not cleaning your filters.
How do you reset a Daikin split system?
You can try resetting your air conditioning by turning off the power on your outdoor unit and on your switchboard and waiting for a few minutes before turning it back on.
To restart your Daikin remote, follow these steps:
- Press and hold down the power button for two seconds
- Click it once to turn it off
- Click it again to turn it back on
