CONTACTOR — STARTS YOUR A/C SYSTEM

CONTACTOR — STARTS YOUR A/C SYSTEM

Your A/C contactor is an electrical switch that sends power to the compressor and condenser fan when your thermostat calls for cooling.

✔ Turns outdoor unit on and off
✔ Sends power to compressor
✔ Powers condenser fan motor
✔ Important for reliable cooling
✔ Essential for daily system operation

⚠️ A worn or damaged contactor can cause no cooling, buzzing noises, stuck contacts, or system failure.

Common signs:
• Outdoor unit not starting
• Clicking or buzzing sounds
• A/C runs constantly
• Intermittent cooling
• Burned or pitted contacts
• System shuts off unexpectedly

Heat, insects, age, and electrical wear can shorten contactor life.

Regular maintenance helps inspect contacts before failure.

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

CONTROL BOARD — THE BRAIN OF YOUR A/C SYSTEM

CONTROL BOARD — THE BRAIN OF YOUR A/C SYSTEM

Your A/C control board manages communication between components and helps your system start, run, and shut down correctly.

✔ Controls system operations
✔ Sends signals to motors and compressor
✔ Helps thermostat communication
✔ Supports safe startup and shutdown
✔ Essential for reliable cooling

⚠️ A failing control board can cause no cooling, blower issues, short cycling, or system shutdown.

Common signs:
• A/C not turning on
• Fan runs constantly
• Outdoor unit not starting
• Intermittent cooling
• Burn marks or electrical smell
• Error codes or random shutdowns

Power surges, moisture, age, or loose wiring can damage the board.

Regular maintenance helps inspect wiring and protect sensitive electronics.

Small board, big control — don’t ignore control board problems.
