York S1-024-19082-017 Heat Relay

The York S1-024-19082-017 Heat Relay is an essential OEM replacement part engineered for precise thermal management in residential and commercial HVAC systems. As a veteran technician knows, maintaining the integrity of the heating control circuit is critical for preventing short-cycling and ensuring efficient heat transfer. This 24V heat relay features robust bimetal actuated contacts and a positive temperature coefficient (PTC) heater, providing the reliable time-delay switching necessary for sequencing heating elements or controlling auxiliary heat in heat pump applications.

Designed specifically to meet York’s stringent performance standards, the S1-024-19082-017 replaces several legacy sequencer relay models, offering a streamlined fit for furnace control boards and electrical cabinets. Its durable construction ensures stable current switching and rapid contact separation, minimizing arcing and extending the operational life of the unit’s heating components. Whether you are troubleshooting a no-heat condition or performing a preventative upgrade, this relay provides the factory-spec compatibility required to restore system efficiency and consistent temperature control without the risk of mismatching non-OEM generic alternatives.

• Direct OEM Compatibility: Specifically engineered for York heating systems, ensuring seamless integration and electrical safety.
• Precise Thermal Control: Maintains accurate timing sequences for heating elements to optimize energy consumption and airflow.
• Heavy-Duty Construction: Built with high-grade electrical components to withstand the rigorous operating temperatures of furnace environments.
• Efficient Troubleshooting: Simplifies repairs for auxiliary heat failures and blower motor sequencing issues.
• Optimal Heat Transfer: Facilitates reliable circuit switching to ensure even heat distribution across the network.

How do I test if the York S1-024-19082-017 is faulty?
Technicians should verify 24V at the relay coil. If the control voltage is present but the load contacts fail to close and pass line voltage to the heating elements, the relay is likely defective and requires replacement.

Can this relay be used for both gas and electric heating systems?
While primarily utilized in electric furnaces and heat pump auxiliary stages for sequencing, it is vital to verify the specific wiring diagram of your unit to ensure this 24V component matches the auxiliary control requirements.

What are the symptoms of a sticking heat relay?
A common symptom is the blower motor or heating elements remaining energized after the thermostat has satisfied the set temperature, often caused by welded contacts within the relay housing.
