Where Is the Reset Button on a Daikin?

Knowing where the reset button on your Daikin AC is, you can operate it easier and simpler. This is known as the button reset technique that can work like a charm for AC that won’t turn on, won’t cool off, or is quite noisy.

Your indoor AC unit has a reset button on the front. Simply press and access it when your AC is experiencing malfunctions. You can see this small red button, which you should press when your unit makes odd noises. You can also use this button when the unit won’t turn on or won’t cool correctly.

You should know that there is another reset button located on the outside. This should be pressed when the AC unit experiences a power outage. Just press gently and you should be good to go. You mustn’t press the button with too much power or strength because the button can be damaged.

How Do I Hard Reset My Daikin?

One of the ways to reset Daikin error codes is the hard reset. Hard reset itself is the best way to reset the AC after a power outage happens. But you can also use this technique when a power surge happens. How to do it?

  • Turn the thermostat off so auto turning won’t be on
  • Find the breaker box. Flip the circuit breaker off.
  • Wait for around 60 seconds before you turn the breaker on again.
  • And then wait for an extra 30 minutes before you can switch on the thermostat again.
  • You can now set the temperature or on Cool Mode.

Another option is to unplug your unit. Do it for a minute. If you use this option, you won’t have to turn off the breaker.
