If your outdoor unit can’t stop running…

Here’s the situation: Your thermostat is at the temperature you want. The air stops blowing and the indoor unit shuts off.

All is fine, but the outside unit keeps running rather than shutting off. What’s wrong?

There are several possible causes. Maybe squirrels chewed on a wire or you accidentally banged something loose if you hit the unit while cutting the lawn.

Or… a compressor contactor in the outside unit shut down. These contacts are in frequent use so they do wear out over time; a technician will check them as part of a periodic inspection.

Contactors are part of the electromagnetic switches operating the system.

A current overload can cause overheating that makes them stick.

Corrosion and dirt also can cause a contactor to go awry.
