York S1-024-19138-001 Relay Control

The York S1-024-19138-001 Relay Control is a critical 24V motor relay designed for precise switching in York HVAC units. This 3PDT relay (Triple Pole Double Throw) features a 24VAC coil and is engineered to handle multiple high-current and low-voltage circuits simultaneously, making it an essential component for furnace relay replacement and blower motor sequencing. As an OEM York replacement part, it ensures exact fitment and electrical compatibility within the control board circuit, preventing the common chatter or contact pitting found in generic universal relays. Designed for high-duty cycle applications, this control relay manages the HVAC blower motor control and integrated logic sequences required for efficient system operation. Field technicians rely on this specific 3PDT 24V relay for troubleshooting electrical failure in residential and light commercial air handlers where reliable switching and coil resistance are paramount for maintaining HVAC system reliability.

Key Technical Benefits

• 3PDT Configuration: Provides three independent switching poles for complex circuit management and simultaneous control of multiple system components.
• OEM Specification: Guaranteed electrical matching for York S1-024-19138-001 ensures proper inductive load handling and prevents premature contact failure.
• 24V Low Voltage Control: Standard 24VAC coil allows for seamless integration with existing 24-volt thermostats and furnace control boards.
• Durable Contact Points: Engineered for minimal resistance and high conductivity to withstand frequent cycling during peak furnace or AC operation.

Common Questions & Technical Support

Can I use a standard DPDT relay to replace this 3PDT model?
No. The York S1-024-19138-001 utilizes triple poles to bridge specific logic paths required by the York control board. Using a relay with fewer poles will leave necessary circuits open, causing system failure.

What are the symptoms of a failing S1-024-19138-001 relay?
Common indicators include a blower motor that fails to engage, audible clicking without component activation, or the indoor fan running continuously even when the thermostat is set to off.

Is this relay compatible with other Johnson Controls brands?
Yes, as an OEM part, it is frequently used across various Johnson Controls brands including Luxaire and Coleman, provided the part number matches the service manual specifications.
