After you have done the first step, you will need to turn off your A/C unit. When you are finished using the air conditioning, locate the breaker that powers the unit. Then press the power button located near the thermostat to reset the thermostat. If the A/C unit is not turning on, turn off the main power supply to the system and press the reset button on the unit.
