York S1-024-19082-032 Sequencer

The York S1-024-19082-032 Sequencer is a critical 24V component designed for managing the staged activation of heating elements in electric furnaces and air handlers. Built for high-reliability circuit control, this 24V heat sequencer prevents electrical overloads by ensuring heater banks and blower motors engage in a specific timed sequence rather than simultaneously. As a heavy-duty HVAC sequencer relay, it is frequently used in York and Luxaire residential electric furnace parts kits to maintain system efficiency during high-demand cycles. The solid-state PTC (Positive Temperature Coefficient) heater provides consistent timing across a wide voltage range, ensuring the heating element relay functions correctly even during low-voltage conditions. Contractors often utilize this part for staged heating control to resolve issues with circuit breakers tripping during the initial heat call. Its rugged construction makes it a preferred OEM-standard replacement for stabilizing current in multi-stage central heating systems.

• Optimized Load Management: Prevents peak demand surges by staggering the startup of resistive heating elements and blower fans.
• Universal Compatibility: Engineered as a direct fit for diverse York HVAC replacement parts configurations and cross-references with part number 209A68.
• Reliable PTC Ignition: The integrated heater element ensures stable switching times regardless of ambient temperature fluctuations.
• Durable Contacts: Field-tested terminals designed to handle high-amperage heating loads in standard 24V control circuits.
• Simple Integration: Standard mounting footprint and quick-connect terminals allow for rapid installation during service calls.

• How do I know if my York heat sequencer is failing? If heating elements stay on after the thermostat is satisfied or if the furnace fan fails to start during a heat call, the sequencer contacts may be stuck or the PTC heater may be open.
• Can this sequencer be used in heat pump applications? Yes, this 24V relay is commonly utilized in air handlers to manage auxiliary heat strips and provide the necessary blower delay in heating mode.
• What is the voltage rating for the control coil? This specific model is designed for standard 24VAC control circuits found in most residential HVAC systems.
