I. Common Causes for Daikin AC Not Turning On
A. Power supply issues
When your Daikin AC refuses to turn on, the first thing to check is the power supply. Several issues can disrupt the power flow, including:
1. Check power outlet and circuit breaker
Start by ensuring that the power outlet is functioning properly. Plug in another device to check if it receives power. If the outlet is fine, move on to the circuit breaker.
Locate the circuit breaker panel in your home and look for the one labeled “HVAC” or “AC.” Check if the breaker has tripped or if it’s in the “off” position. If it has tripped, flip it back to the “on” position and see if the AC turns on.
