CONTACTOR — THE SWITCH THAT STARTS YOUR A/C

CONTACTOR — THE SWITCH THAT STARTS YOUR A/C

Your A/C contactor is an electrical component that receives the thermostat signal and sends power to the compressor and outdoor fan motor.

✔ Helps your A/C start properly
✔ Sends power to key components
✔ Supports reliable cooling
✔ Important for daily operation
✔ Helps system respond to thermostat calls

⚠️ A worn or burned contactor can cause no cooling, clicking noises, stuck running, or system failure.
Common signs:

• Outdoor unit not turning on
• Rapid clicking sounds
• A/C runs constantly
• Warm air from vents
• Intermittent cooling
• Burn marks or buzzing sounds

Heat, ants/insects, pitted contacts, voltage wear, and age can damage the contactor over time.
Regular maintenance helps inspect and replace weak contactors before failure.

Small part, big job — don’t ignore your A/C contactor.
