To manually reset a central air conditioning system, perform a controlled power cycle at your electrical panel. Step 1: Turn your indoor thermostat mode switch to the "Off" position. Step 2: Locate your outdoor condensing unit's nearby emergency shut-off box (often mounted on the exterior wall) and pull the plastic disconnect block or flip the switch to "Off." Step 3: Go to your main indoor electrical breaker panel and turn off the HVAC breaker. Step 4: Wait 15 minutes, turn all breakers and disconnect switches back on, and reset your thermostat to cooling mode. Verification: Check that the outdoor unit fan begins spinning and blowing warm air upward.
