CONTACTOR — THE SWITCH THAT POWERS YOUR A/C
CONTACTOR — THE SWITCH THAT POWERS YOUR A/C
Your A/C contactor is an essential electrical component that controls the flow of power to your compressor and outdoor unit. When your thermostat calls for cooling, the contactor makes it happen.
✔ Sends power to the compressor & fan
✔ Ensures proper system start/stop
✔ Supports reliable operation
✔ Helps maintain consistent cooling
✔ Keeps your system running safely
⚠️ A worn or damaged contactor can cause your A/C to fail, short cycle, or not turn on at all.
Common causes of contactor issues:
• Burnt or pitted contact points
• Electrical wear over time
• Dirt, insects, or debris inside the unit
• Voltage issues
Warning signs:
• A/C not turning on
• Clicking noise from outdoor unit
• System turning on and off repeatedly
• Outdoor unit not running
• Weak or no cooling
Ignoring a faulty contactor can lead to bigger electrical problems and system failure.
Regular maintenance helps catch contactor wear before it becomes a costly repair.
Small switch. Big role in your comfort. ❄️
