Description
The York S1-024-19082-031 is an OEM 24V Heat Sequencer Relay engineered specifically for York electric heating systems. Heat sequencer relays play a critical role in electric furnace and air handler operation by staging the activation of heating elements in a controlled sequence — preventing simultaneous element startup, reducing electrical demand spikes, and protecting the system from excessive current draw.
Why Heat Sequencers Matter
Without a properly functioning heat sequencer relay, all electric heating elements in a system may attempt to energize at once, causing nuisance tripping of circuit breakers, premature component wear, and uneven heat distribution. The S1-024-19082-031 restores proper staged operation, ensuring each heating element comes online in a timed, orderly fashion for smooth, efficient performance.
Key Features
- OEM York replacement part — engineered to exact factory specifications
- 24V control voltage for compatibility with standard low-voltage thermostat circuits
- Staged sequencing of electric heating elements for reduced inrush current
- Helps prevent nuisance circuit breaker trips during heating startup
- Direct drop-in replacement for failed or degraded heat sequencer relays in compatible York units
- Supports reliable, consistent heat output throughout the heating cycle
Application
Designed as a direct replacement for York electric furnaces and air handlers that utilize sequenced electric heat strips. Always verify compatibility with your specific York model before installation.
Installation Notes
- Disconnect all power before servicing electrical components
- Match wiring connections to original relay terminals per the unit wiring diagram
- Consult a licensed HVAC technician for installation if needed
