York S1-025-19499-002 Temp Control

The York S1-025-19499-002 Temp Control is an essential OEM SPST (Single Pole Single Throw) temperature control engineered for precision sensing in residential and commercial HVAC units. This snap-acting York replacement part is designed to cycle components based on ambient or surface temperatures, specifically calibrated with a 45 degree F open and 55 degree F close setpoint. As a close-on-rise switch, it ensures reliable circuit engagement when temperatures reach the upper threshold, providing critical protection and operational logic for compatible furnace and air handling assemblies. Built for long-term durability in high-demand environments, this limit control switch maintains thermal safety and system efficiency for service technicians and contractors maintaining York, Luxaire, or Coleman equipment. Utilizing a standard mounting configuration, the S1-025-19499-002 offers a direct-fit solution to resolve cycling issues and restore factory-spec performance to the HVAC system.

• OEM Precision: Genuine York component ensures exact calibration and electrical compatibility with factory control boards.
• Reliable Thermal Cycling: Features a fixed 10-degree differential (45°F Open / 55°F Close) for consistent temperature regulation.
• Rugged Construction: Built to withstand the vibration and thermal stress typical of industrial and residential air handlers.
• Easy Integration: Simplified SPST design facilitates fast installation into existing wiring harnesses for reduced job-site labor.

• What does a 45 degree open and 55 degree close setting mean for my system? This SPST temperature control acts as a switch that opens the circuit when the temperature drops to 45°F and closes it when it rises to 55°F, often used to manage low-ambient cooling or specific heating stages.
• Is this S1-025-19499-002 compatible with other brands? While designed as a York replacement part, it is also frequently found in equipment under the Johnson Controls umbrella, including Luxaire and Coleman models.
• How do I know if my temperature limit switch is failing? Common indicators include the system failing to start despite a call for cooling/heating or short-cycling due to inaccurate thermal sensing.
