York S1-024-19082-738 Relay

The York S1-024-19082-738 Relay is an essential Heat Sequencer Time Delay Rly specifically designed for the staging of electric heating elements in York, Luxaire, and Coleman air handlers. This OEM component manages the sequential activation of heating banks to prevent excessive inrush current, which can lead to tripped breakers or damage to the electrical service. As a critical HVAC time delay relay, it utilizes a 24V control circuit to actuate internal bimetal heaters, providing the necessary timing differential between stages. Field technicians rely on the S1-024-19082-738 for its precise contact closure and opening cycles, ensuring the blower motor and heating elements operate in the correct synchronization. When troubleshooting York furnace heating elements that fail to energize or stay stuck in the "on" position, this electric furnace sequencer is the standard replacement to restore factory-spec operation. Its robust terminal layout allows for direct mounting and wiring without the need for field modifications or bracket adjustments.

• Direct OEM replacement for York S1-024-19082-738, ensuring terminal alignment and timing accuracy.
• Engineered for 24V control systems found in standard residential air handlers and furnaces.
• Heavy-duty construction designed to handle the high amperage of electric resistive heat banks.

Common Questions

• What happens if the sequencer fails in the closed position? If the S1-024-19082-738 contacts weld shut or fail to open, the heating elements will remain energized even after the thermostat is satisfied, potentially causing the limit switch to trip.
• Can this relay be used to control the fan motor? Yes, in many York configurations, one set of contacts on the Heat Sequencer Time Delay Rly is dedicated to energizing the blower motor to ensure airflow before the elements reach peak temperature.
• How do I verify if the time delay is functioning correctly? A technician should measure the voltage at the output terminals after the 24V coil is energized; if the elements do not receive power within the manufacturer's specified timing window, the sequencer requires replacement.
