This capacitor stores and releases electrical energy to help an AC motor start and run smoothly. Replacing a weak or failed capacitor can restore reliable motor operation and reduce humming, no-start, or stall conditions.
- Provides the phase shift and starting torque an induction motor needs to start
- Helps the motor reach and maintain proper speed under load
- Common symptoms of a failing capacitor: motor hums but won't start, intermittent starts, slow or stalled rotation, or frequent thermal trips
- Visible clues may include a swollen case or leaking residue
What's included: One capacitor Install notes:
- Disconnect power to the appliance before servicing; verify no voltage is present
- Capacitors can retain a charge—discharge safely before handling
- Note wire positions; move leads to the new capacitor one at a time and ensure snug terminal fit
- Reuse the original bracket/clip if applicable and secure the capacitor to prevent vibration
