How to Choose the Right Capacitor for Your Appliance

Capacitors are small but critical components used in motors and HVAC systems.

Choosing the wrong one can cause:

  • motor failure
  • overheating
  • equipment not starting

What to Look For:

Every capacitor has key ratings printed on it:

  • Microfarads (MFD or µF) → must match exactly
  • Voltage (VAC) → can be equal or higher, never lower

Example:

  • 40/5 MFD 440V
  • The 40 and 5 must match exactly

Common Mistakes:

❌ Using the wrong MFD rating
❌ Guessing based on size
❌ Replacing with “close enough”

Pro Tip:

Take a picture of your old capacitor before coming in — it makes matching much faster.

When in Doubt:

Capacitors are one of the easiest parts to replace — if you get the right one.
