Description
Product Summary
The Supco SPP7S Super Seven Hard Start Kit is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Hard Start Kit Positive Temperature Coefficient (PTC) Relay and Start Capacitor SPP Series.
Hard start kits give a struggling compressor the extra starting torque it needs on low-voltage days, after long off-cycles, or when an aging compressor begins to trip on locked-rotor amps. Adding the correct hard start reduces start-up current spikes, cuts down on nuisance breaker trips, and can extend compressor life on PSC-type single-phase systems. Always match the kit to the compressor horsepower and system voltage.
