Rheem-Ruud 42-23116-06 Sequencing Relay

The Rheem-Ruud 42-23116-06 is a professional-grade 24V sequencing relay designed for precise staged heating control in electric furnaces and air handlers. Featuring a DPST (Double Pole Single Throw) configuration with Normally Open (N/O) contacts, this OEM replacement part handles up to 25A resistive loads per pole at 120/230V. This relay serves as a critical interlock, managing the timing of heating elements and blower motor activation to prevent high inrush current and circuit breaker trips. The integrated heater coil operates at 24VAC with a maximum consumption of 0.55A, utilizing a bimetal disc for reliable switching delays. This unit replaces several older legacy components and is essential for maintaining the safety parameters of RBEH, RBHK, and RBHN series air handlers. For contractors, the standard angle bracket and 1/4-inch quick-connect terminals ensure a drop-in HVAC sequencer replacement without extra field modifications.

• OEM Compatibility: Exact drop-in replacement for Rheem and Ruud 42-23116-06 units, ensuring factory-spec timing and safety interlocks.
• Dual-Circuit Control: The DPST N/O design allows for simultaneous control of multiple heating banks or a combination of heat and blower stages.
• Heavy-Duty Contact Rating: Rated for a 14A FLA at 120V and 7A FLA at 230V, providing robust electric furnace sequencer performance under high-demand cycles.
• Optimized Sequencing: Features factory-calibrated "on" and "off" timing (Pole 1 On: 10-40s; Pole 2 On: 30-60s) to reduce electrical stress on the home’s power grid.

• Can I use this relay to replace a 3PST model? No, this is a Double Pole Single Throw relay. If your existing circuit requires a third pole for the blower or an additional heater bank, you must use the specific 3PST variant (such as the 42-23116-07).
• Why is my blower running but the heat is cold? This often points to a failed bimetal disc within the sequencing relay. If the 24V coil is energized but the high-voltage contacts fail to close after 60 seconds, the 42-23116-06 likely requires replacement.
• Is the mounting bracket included? Yes, the unit comes with a pre-installed angle bracket featuring two standard mounting holes for secure attachment to the air handler chassis.
