Lennox Motor Start Capacitor Round

The Lennox Motor Start Capacitor is a round start capacitor for HVAC and refrigeration equipment. It gives the compressor motor a short burst of extra electrical energy at startup. This helps the motor overcome initial inertia and reach running speed. Lennox motor start capacitors are also called compressor start capacitors or hard start capacitors. They are a common replacement part when a unit hums, struggles to start, or fails to start.

Key Features:

• Round-case design for use in air conditioning and refrigeration motor start circuits
• Provides a temporary boost of starting torque at motor startup
• Lennox-branded replacement part for reliable, consistent starting performance
• Terminal connections allow straightforward installation in the control compartment

Start capacitors are intended for brief, intermittent duty during motor startup. Always disconnect power and safely discharge the capacitor before servicing. Choose the variant that matches the capacitance and voltage ratings of the original part.
