York S1-025-32652-000 Limit Switch

The York S1-025-32652-000 Limit Switch is a critical high-limit safety control engineered for York HVAC units and compatible furnace systems. This SPST (Single Pole Single Throw) switch features an auto-reset functionality, designed to interrupt the electrical circuit when internal plenum temperatures reach the upper threshold of 230°F. Once the heat exchanger cools to the 200°F cut-in point, the limit switch automatically closes to restore system operation. As an OEM replacement part, it ensures precise over-temperature protection, preventing heat exchanger damage and maintaining furnace safety standards. This 200-230F limit switch is built for technicians who require genuine York parts to maintain system integrity and avoid the nuisance tripping common with low-quality aftermarket alternatives.

• Precise Thermal Regulation: Operates on a strict 200°F to 230°F range to provide reliable automatic temperature control.
• OEM Compatibility: Exact York S1-025-32652-000 specifications ensure a drop-in fit for rapid field replacement.
• Auto-Reset Logic: Eliminates manual resets after temporary overheating events, reducing unnecessary service calls.
• Industrial-Grade Build: Engineered to withstand the high-cycle demands of modern residential and commercial heating systems.

What causes a York limit switch to trip frequently?
Frequent tripping usually indicates restricted airflow, often due to a clogged air filter, blocked return vents, or a failing blower motor. If the S1-025-32652-000 fails to reset, the internal bimetal disc may be fatigued, requiring a full replacement.

Is the S1-025-32652-000 compatible with other furnace brands?
While designed as a York OEM part, this limit switch may fit other Johnson Controls brands (such as Luxaire or Coleman) provided the temperature ratings and mounting footprints match the original equipment specifications.

Can I test this switch with a multimeter?
Yes. Under normal (cool) conditions, the limit switch should show continuity (0 ohms). If the switch is open at room temperature, the internal contacts have failed, and the part must be replaced to restore furnace operation.
