How to Reset a Tripped Breaker on Your AC

Introduction

A tripped breaker is one of the simplest reasons an AC won’t turn on. Resetting it is quick and can save you an unnecessary service call. Here’s exactly how to do it safely.

Step-by-Step Guide

1. Identify the AC Breaker

   • Go to your home’s main electrical panel (basement, garage, or utility closet).

   • Look for a breaker labeled “AC,” “Outdoor Unit,” or “Condensing Unit.”

2. Confirm the Trip

   • A tripped breaker will sit between On and Off, or you may see the handle pointing sideways.

   • Never force it.

3. Power Off the Breaker

   • Wearing rubber-soled shoes, flip the breaker fully to the Off position.

   • This discharges any residual power.

4. Reset to On

   • Firmly flip the breaker back to On until you feel it click.

   • You should hear the outdoor unit’s fan motor engage.

5. Verify AC Operation

   • Return to your thermostat and attempt to start cooling.

   • Listen for the compressor and fan—confirm airflow after a minute.

Troubleshooting Tips

• If the breaker trips again immediately, stop and call a professional—it indicates a deeper electrical or compressor fault.

• Ensure no large appliances on the same circuit run simultaneously.
