If the unit is plugged in and the breaker is fine, the issue may be with the thermostat.
Ensure the thermostat is set to “cool” and that the temperature is below the room temperature.
If the thermostat is determined wrong, the problem may be with the air conditioner. Check for any loose wires and ensure the AC receives power from the breaker.
Why Won’t My Daikin AC Turn On? Causes and Solutions
If you’re wondering why your Daikin AC unit won’t turn on, several potential causes exist.
One of the most common causes is a tripped circuit breaker or a blown fuse.
In this case, you can simply reset the breaker or replace the fuse to get the AC up and running again.
Another possibility is a malfunctioning thermostat, which can prevent the AC from turning on. In this case, you may need to replace or repair the thermostat.
A dirty air filter can also cause the AC to malfunction, as it restricts airflow and reduces the cooling capacity.
Therefore, it is important to clean or replace your AC filter regularly to avoid such issues.
If you’re not comfortable troubleshooting the problem yourself, it’s best to contact a professional HVAC technician who can diagnose the issue and recommend the appropriate repair or replacement solution.

What to do when Daikin AC stops working?
When your Daikin AC stops working, there are a few things you can do to troubleshoot the issue.
First, check to see if the AC is receiving power.
If the AC is plugged into an outlet, check to see if the outlet is working by plugging in another appliance.
If the outlet is working, check the circuit breaker or fuse box to see if the AC circuit has been tripped.
You can reset the breaker or replace the fuse if the circuit tripped.
If the AC receives power and the course is not tripped, check the thermostat to see if it is set to the correct temperature.
The AC unit should be running if the thermostat is set correctly. If the compressor is not running, check if the AC unit is frozen.
Once the unit is thawed, turn the AC back on. If the compressor is running but the AC unit is not cooling, check the air filters. If the air filters are dirty, replace them.
You can check the air filters if they are clean. To clean the coils, if they are dirty, use a solution of water and vinegar. Check the refrigerant level to see if the coils are clean.
