Rheem-Ruud 42-23116-08 Sequencing Relay

The Rheem-Ruud 42-23116-08 Sequencing Relay is a vital OEM replacement part designed for precise load management in electric furnaces and air handlers. This 24V DPST N/O sequencing relay controls the staging of heating elements to prevent excessive amperage draw and circuit breaker trips during startup. Rated for 8kW, 10kW, and 12kW systems, this double-pole single-throw relay ensures that furnace components, such as heat strips and blower motors, energize in the correct order. By utilizing a 24-volt coil to manage high-voltage circuits, it provides the timing delay necessary for stable system operation. As a 24V HVAC heat sequencer, it is engineered for direct compatibility with Rheem, Ruud, and Weather King equipment, replacing legacy part numbers like 42-25270-51 and 42-23116-04. Its normally open contacts offer a reliable switching solution for multi-stage heating applications, maintaining efficiency and protecting the integrity of the electrical distribution within the HVAC sequencing control system.

• OEM Compatibility: Direct replacement for Rheem-Ruud 42-23116-08, ensuring exact fitment for specific air handler models.
• Circuit Protection: Prevents simultaneous high-demand loads to avoid nuisance tripping of the primary breaker.
• Multi-Stage Control: Effectively manages staging for 8kW to 12kW electric heat configurations.
• Durable DPST Design: Features two poles and a normally open configuration for robust electrical switching.
• Standard 24V Logic: Integrates seamlessly with standard 24VAC thermostat and control board signals.

• How do I tell if my sequencing relay has failed? If your heating elements turn red but the blower motor fails to start, or if the furnace trips the breaker immediately upon startup, the sequencer timing may be compromised.
• Is this compatible with other brands? While designed as an OEM Rheem-Ruud part, it is also found in Weather King and Corsaire units; always verify the specific part number on your existing relay.
• Can this relay control multiple heat strips? Yes, this DPST N/O relay is typically utilized to stage up to two heating elements or a combination of an element and a fan motor.
