Why Use a Hard Start Device?
Compressors can struggle to start under high-load conditions, especially in systems with low voltage, long line sets, or aging components. A hard start device provides the additional starting torque needed to get the compressor running quickly and efficiently, reducing wear on the motor windings and protecting the overall refrigeration system.
Installation
The 2-wire design makes this hard start device easy to install — simply connect to the compressor’s run and start terminals. Always follow York’s installation guidelines and local electrical codes. Consult a licensed HVAC technician for proper installation.
