A contactor is an electromechanical device that helps control the flow of electricity in a central air conditioner. It acts as a switch, allowing the current to pass through or interrupt the electrical circuit. The air conditioner contactor prevents overload, protects the compressor, and helps regulate the cooling process.
When the thermostat signals the air conditioner to start cooling, the central air conditioning contactor receives an electrical signal from the control board. The central AC contactor's electromagnet is then energized, pulling down the contactor's armature, allowing the electrical current to flow. This action engages the compressor and other components to start the cooling process. When the desired temperature is reached, the electrical signal is cut off, de-energizing the central air contactor and stopping the flow of electricity.
Like any other air conditioning part, central air contactors can develop issues over time. Look out for these signs which may indicate a faulty contactor:
