To reset your outside AC unit, you can follow these steps:
Turn off the power: Locate the power disconnect switch for your AC unit. It is usually located near the unit or on an adjacent wall. Flip the switch to the "Off" position to cut off power to the unit. Alternatively, you may need to turn off the breaker dedicated to the AC unit in your home's electrical panel.
Wait for a few minutes: After turning off the power, allow the AC unit to remain without power for at least 5 minutes. This waiting period helps ensure that any capacitors within the unit are discharged, allowing for a proper reset.
Restore power: After the waiting period, turn the power back on by flipping the disconnect switch to the "On" position or by resetting the breaker in the electrical panel.
Reset the thermostat: Go to your thermostat inside your home and set it to the desired temperature for cooling. Ensure that the thermostat is set to the "Cool" mode and that the temperature setting is lower than the current room temperature.
Monitor the AC unit: Observe the AC unit to see if it starts up and begins cooling. You should hear the unit's compressor and fan running. It may take a few minutes for the system to kick in and start cooling your home.
If the AC unit fails to reset or does not start functioning properly after following these steps, it may indicate an underlying issue. In such cases, it's recommended to contact a professional HVAC technician to diagnose and resolve any problems with your AC unit.
