Rheem-Ruud 42-19736-02 RELAY

The Rheem-Ruud 42-19736-02 is a high-performance 24V SPDT Relay engineered for precise switching in residential and light commercial HVAC systems. Designed as a genuine OEM repair part, this Single Pole Double Throw relay provides reliable control over two separate circuits, making it an essential component for furnace control boards, fan logic, and air conditioning sequencing. With a robust 24VAC coil and a contact rating typically capable of handling up to 10 Amps, it ensures consistent electrical continuity and minimizes voltage drop across the system. This electro-mechanical device is built with high-grade internal contacts to prevent pitting and arcing, extending the service life of both the relay and the peripheral components it controls. The compact terminal layout allows for straightforward integration into existing control enclosures, providing a direct-fit solution for Rheem-Ruud HVAC parts replacement and maintenance. This specific 24 V switching relay is characterized by its high switching frequency and thermal stability, ensuring reliable operation under varying indoor equipment loads.

• OEM Reliability: Ensures precise mechanical fit and electrical compatibility with factory-installed Rheem and Ruud equipment.
• SPDT Configuration: Allows for versatile control functions including normally open (NO) and normally closed (NC) switching scenarios.
• Efficient Coil Power: Optimized for 24V control circuits, drawing minimal current while maintaining high holding force.
• Durable Construction: Heavy-duty housing and terminal pins designed to withstand high-vibration HVAC environments.

• Can this relay replace the 42-19736-04? Yes, this part number is frequently cross-referenced with and can replace several 42-19736-XX series and 8201-5537 variations, provided the coil voltage and contact amperage match your system requirements.
• How can I tell if my current relay has failed? Technicians often look for signs like a "chattering" sound, charred terminals, or high resistance across the closed contacts using a multimeter.
• Is this relay suitable for fan motor control? This SPDT Relay is commonly utilized for fan speed switching or as an isolation relay for low-voltage thermostats to protect circuit boards from higher amperage draws.
