CAPACITOR — STARTS AND RUNS YOUR A/C SYSTEM
CAPACITOR — STARTS AND RUNS YOUR A/C SYSTEM
Your A/C capacitor stores and releases electrical energy to help start and run the compressor, condenser fan motor, and blower motor.
✔ Helps compressor start properly
✔ Powers fan motors efficiently
✔ Supports reliable cooling
✔ Reduces strain during startup
✔ Important for daily operation
⚠️ A weak or failed capacitor can cause no cooling, humming sounds, hard starts, or system shutdown.
Common signs:
• Outdoor unit not starting
• Humming noise from unit
• Fan not spinning
• Warm air from vents
• System struggles to start
• Breaker trips or random shutdowns
Heat, age, voltage issues, and constant summer use can shorten capacitor life.
Regular maintenance helps test capacitor strength before failure.
Small part, big power — don’t ignore your A/C capacitor.
