Rheem-Ruud 42-23116-01 Sequencing Relay

The Rheem-Ruud 42-23116-01 Sequencing Relay is a vital 24V SPST-N/O control engineered for precision logic in residential and commercial electric furnaces. As an essential HVAC sequencer replacement, this component manages the timed staging of heating elements to prevent localized grid overload and circuit breaker trips during high-amperage start-up cycles. Operating with 1/4 inch quick connects, this relay features a reliable bimetal heater that initiates a 1-30 second "On" delay and a 40-90 second "Off" delay, ensuring the blower motor and heat strips remain synchronized for optimal heat exchange efficiency.

For field technicians, the 42-23116-01 provides a universal mounting profile via an angle bracket with two pre-drilled holes. It supports a motor FLA of 14A at 120V and 7A at 230V, with a pilot duty rating of 125VA. Whether you are performing an electric furnace repair or troubleshooting staged heating controls, this genuine OEM-spec relay is the industry standard for maintaining system integrity in Rheem-Ruud heating systems. Its rugged construction is designed to withstand 0.9A maximum heater power consumption, providing long-term reliability in demanding thermal environments.

• Optimized Power Management: Prevents electrical surges by staging heating elements sequentially.
• Universal Compatibility: Direct replacement for various Rheem and Ruud 5 kW sequencer configurations.
• Technician-Ready Design: Standard 1/4 in. quick connects and angle bracket mounting speed up installation time.
• Durable Performance: High-quality bimetal switch designed for consistent timing cycles across thousands of operations.

• Why is my furnace blower running but the air is cold? A failed sequencing relay often prevents power from reaching the heating elements even if the motor circuit is engaged.
• Can I replace a multi-pole sequencer with this SPST relay? This SPST-N/O relay is designed for single-circuit control; always verify your wiring diagram to ensure proper pole count.
• How do I test this relay in the field? Use a multimeter to check for 24V at the heater coil and verify continuity across the load terminals after the appropriate delay period.
