Lennox 97W31 Relay Sequencer
The Lennox 97W31 Relay Sequencer is a critical OEM component designed to manage the staggered activation of heating elements and blower motors in residential and commercial air handlers. This 2-pole relay sequencer features a high-performance Nova Coil 76701134 design, ensuring precise timing for multi-stage electric furnaces. As a direct replacement part, it handles contact ratings of 5A at 277VAC and 10A at 125/250VAC, providing the necessary switching capacity for low voltage control circuits and high-voltage heating loads up to 30VDC. By utilizing this HVAC sequencer relay, technicians can prevent circuit overloads and nuisance tripping during the initial startup phase. Its compact footprint facilitates a seamless fit in tight control cabinets, maintaining the integrity of the heat sequence and local safety protocols. This genuine Lennox part is essential for restoring proper heating operation and air distribution across various air handler configurations.
Key Benefits for Technicians:- Precise Multi-Stage Timing: Coordinates the staged power-up of heating strips to mitigate voltage drops and protect the transformer.
- Direct OEM Compatibility: Engineered specifically for Lennox air handlers, ensuring terminal positions and mounting holes align for fast field installation.
- Enhanced Contact Reliability: Rated for 10A at 250VAC, the 2-pole configuration supports demanding electric heat applications.
- System Protection: Delays the blower motor appropriately to ensure the heat exchanger reaches temperature before air distribution begins.
- Can the 97W31 replace single-pole sequencers? This is a 2-pole unit; always verify your specific wiring diagram as extra poles may be used for additional heater banks or fan interlocks.
- What are the symptoms of a failing sequencer? Common indicators include heating elements staying energized after a call for heat or the blower motor failing to kick on during the heating cycle.
- Does this relay support 24V control systems? Yes, the 97W31 is designed for standard 24V HVAC control signals to trigger the internal heater and close the high-voltage contacts.
