The power flickers, comes back, and the air conditioner does not. Before you decide it is broken, understand what it is probably doing: waiting on purpose.
Give it five minutes before you touch anything
Most thermostats hold the compressor off for about five minutes after any shutdown so the pressure inside the system can equalize. Honeywell puts that delay at up to five minutes — which is the real version of the “three minute rule” people search for.
A thermostat that just rebooted after an outage may not run that timer on its own, so wait it out yourself rather than start flipping switches. Starting a compressor against unequalized pressure is how a nuisance becomes a repair.
There may not be a reset button
Some outdoor units have a small red or yellow reset button on the condenser. Plenty do not, and hunting for one you do not have wastes an afternoon.
The real reset is power. Thermostat OFF, breaker for the outdoor unit off, back on, then thermostat to COOL. Carrier recommends leaving the breaker off for 30 minutes — longer than most people expect, and it does not hurt anything.
Check the disconnect too
There is a pull-out disconnect in a small box on the wall beside the outdoor unit. It gets bumped by lawn crews, pressure washers and anyone working near the pad. Make sure it is fully seated before you conclude the system is dead.
When to stop and call
Stop if the indoor fan runs but the outdoor unit only hums or sits silent — that is usually a capacitor, and it is a part, not a setting.
And if the breaker trips the moment you set it, leave it off and call. A breaker that trips immediately is doing its job, and resetting it repeatedly is how a fault becomes a fire.
Summer storms take the power down often enough here that the sequence above is worth knowing by heart — and what a surge actually damages is usually the control board rather than the compressor, which we go into on the Orange Park page.
