Shutting off power is a crucial step in resetting your AC unit. Locate the breaker switch that runs to your central heating and air conditioning system. Switch it to the “off” position.

Wait at least a full minute before switching the breaker back to the “on” position. This allows the system to clear any residual charge.

If your AC unit has an isolator switch, you can also shut off power by locating the isolator switch, usually on the outdoor unit. Turn it off and wait for 30 minutes to allow the appliance to dispel electrostatic charge.

From the Isolator Switch

The isolator switch is a safety feature that's often overlooked, but it's a crucial part of your air conditioner's electrical system. It's located between the equipment and the main electrical supply.

An isolator switch differs from a circuit breaker because it doesn't disconnect the electrical supply when there's an overcurrent. Instead, it's designed to enhance safety during maintenance and repairs.

After waiting, you can try turning the lever again, and your AC should restart without a problem. Remember, the 30-minute wait is crucial to ensure the safe operation of your air conditioner.

After 5 minutes, restore power to the unit. Give the unit a few minutes to discharge. If you switched off power to the AC unit at the electrical disconnect, turn that back on first. Then, flip the breaker or breakers to the on position.

Wait 1 minute before turning the thermostat back on. Give your AC unit a chance to power back on. Then, restore power to the thermostat and set it to "cool." Some HVAC companies recommend waiting 30 minutes to turn your thermostat back on to give the unit more time to reset the internal breaker.
