Description
The Carrier KSAHS1701AAA Hard Start Kit is a genuine OEM accessory engineered to improve compressor startup performance in Carrier air conditioning and heat pump systems. By delivering a powerful boost of starting torque, this kit helps the compressor overcome the pressure differential present at startup, reducing electrical demand and mechanical stress on the motor windings.
Why Use a Hard Start Kit?
Compressors that struggle to start — especially on low-voltage circuits, aging equipment, or systems with high static pressure — can draw excessive amperage, trip breakers, and suffer premature wear. The KSAHS1701AAA addresses these issues by supplementing the run capacitor with additional start capacitance and a potential relay, enabling a fast, clean startup every time.
Key Features
- Genuine Carrier OEM hard start kit — engineered for precise compatibility
- Increases compressor starting torque for reliable cold starts
- Reduces inrush current and startup amperage draw
- Helps prevent nuisance tripped breakers and blown fuses
- Minimizes mechanical stress on compressor motor windings
- Extends overall compressor and system service life
- Ideal for systems experiencing slow or failed startups
Applications
- Carrier residential and light commercial air conditioning systems
- Carrier heat pump systems
- Systems operating on low-voltage or long-run electrical circuits
- Aging equipment requiring startup assistance
Installation
Install this hard start kit in parallel with the existing run capacitor on the compressor. Always follow Carrier installation instructions and applicable local electrical codes. Installation should be performed by a qualified HVAC technician.
