How to reset the Daikin air conditioner after a power outage

If you had experienced a power outage and your Daikin air conditioner won’t start after power is restored, follow these steps to reset the entire system and see if it will stop acting up afterward

Switch off your AC system

The first thing you need to do is shut down your air conditioner via your thermostat.

Just look for a system switch on your device(your thermostat) and push it to the off position.

Turn off the air conditioner

You should do this at the circuit breaker – and that is after turning the entire system off (using the thermostat) as explained above.

Just locate the switch controlling your Daikin air conditioning system(at the circuit breaker) and then flip it off.

Turn the AC back on (via the circuit breaker)

Next flip the circuit breaker to the ON position….there’s no need to wait for a few minutes here like it is the norm when resetting these kinds of systems so turn the breaker back on right after the previous shutoff

Allow thirty minutes

These systems take about 30 minutes for their circuitry (internal) to successfully reset so set your time and countdown some thirty minutes- you can be doing other chores

Restart your Air Conditioning System(via the thermostat)

After the 30 minutes have lapsed, turn your AC system back on –push the system switch on the thermostat back on.

You Air Con should start up without a hitch once you do that.

If it does not- and you have followed every step above correctly- then it may have developed some other fault due to the power outage.


Wrap up

If you have tried resetting your air conditioner and still it is not working, you can it take it back to the company for service if it is still under warranty.

Otherwise, you can call in an authorized repair person to check it(your friends, neighbors, or family members could have some referrals)
