York S1-025-19499-002 SPST Temperature Control, 45°F Open / 55°F Close

Description

The York S1-025-19499-002 is an OEM single-pole, single-throw (SPST) temperature control designed for precise, reliable switching in York HVAC systems. Engineered to open the circuit at 45°F and close it at 55°F, this temperature controller provides accurate low-temperature protection and system sequencing to keep your equipment operating safely and efficiently.

Key Features

• OEM York replacement part — ensures direct fit and reliable performance
• SPST switching configuration for straightforward circuit control
• Opens at 45°F — protects against low-temperature fault conditions
• Closes at 55°F — restores circuit continuity as temperature recovers
• Designed for use in York heating and cooling equipment
• Maintains consistent temperature setpoints for dependable system operation

Application

This temperature control is commonly used in York HVAC units to monitor and respond to low ambient or refrigerant temperatures. When temperatures drop to 45°F, the SPST switch opens to interrupt the circuit and prevent damage or unsafe operation. Once temperatures recover to 55°F, the switch closes to resume normal system function. Its OEM design ensures compatibility and longevity in York equipment.
