I also had this problem in my AC but by trying some fixes by doing it myself, I got the issue resolved. Here is what I did.

What are the possible causes of Daikin AC not working

One possible cause for your Daikin AC not working could be that the circuit breaker has tripped. Another possibility is that the power outlet is not working. If neither of these is the case, then it could be that the Daikin AC remote control is not working.

Additionally, it could be that the batteries in the remote control are dead. It is also possible that there is something wrong with the AC unit itself. Finally, it could be that there is an issue with the ductwork. Some other problems are also mentioned below.

The switch is turned off

If the switch is turned off, the first thing you should check is the power source. The second thing you should check is the circuit breaker.

If the circuit breaker has tripped, simply reset it and turn the switch back on. If there is no power or the breaker won’t reset, then you’ll need to call an electrician.

The power cord is loose

If the breaker is off, it needs to be turned on. Once the breaker is on, check to see if the unit is getting power. If the unit is not getting power, check the wiring to see if there are any loose connections.

If there are loose connections, tighten them up and see if that fixes the problem. In case the problem persists, you may need to replace the breaker.

The breaker is off

Before you do anything, check to see if the breaker is off. If it is, turn it on and see if that fixes the problem. If not, check to see if there is a power outage in your area. In case there is, wait for the power to come back on and then try again.

If the power is on and the breaker is on, but the light is still blinking, it could be a sign that the compressor is not working. In this case, you’ll need to call a professional for help.

The cooling coil inside is clogged or dirty

The first thing you should check if your Daikin AC is not working and the light is blinking is the cooling coil inside. This part can become clogged or dirty over time, which will prevent it from working properly.

To clean it, simply remove the coil and rinse it off with water. You may also need to use a brush to remove any stubborn dirt. Once you’ve cleaned the coil, reassemble the unit and see if it’s working properly. If not, you may need to replace it entirely.

The air filter has been removed or damaged

The air filter is an important part of the AC unit and helps to keep the unit clean. If the air filter is removed or damaged, it can cause the unit to malfunction.

To fix this, check the air filter and make sure it is not damaged. If it is, replace it with a new one. You should also check the unit for any blockages that could be preventing proper airflow.
