York S1-025-47870-000 Temperature Control 65°F Open 50°F Close SPST

Description

The York S1-025-47870-000 is an OEM temperature control switch engineered for precise low-temperature detection and circuit protection in York HVAC systems. Featuring a Single Pole Single Throw (SPST) switching configuration, this control opens at 65°F and closes at 50°F, making it an ideal freeze-protection or low-limit safety device in air handlers, heat pumps, and related HVAC equipment.

Key Features

• OEM York replacement part — direct-fit for compatible York equipment
• SPST switching action for reliable single-circuit control
• Opens at 65°F to interrupt the circuit and trigger a protective response
• Closes at 50°F to restore circuit continuity once safe temperatures return
• Designed for freeze-protection and low-temperature limit applications
• Durable construction built to York’s OEM quality standards

Application

This temperature control is commonly used as a freeze stat or low-limit thermostat within York HVAC systems. When air or coil temperatures drop to potentially damaging levels, the switch opens at 65°F to shut down the system or trigger an alarm, then automatically resets by closing at 50°F once conditions normalize — protecting equipment and ensuring safe operation.
