Lennox 13W22 Sequencer
The Lennox 13W22 Heat Sequencer is a critical multi-stage relay designed for precise staging in electric furnaces and air handlers. As a direct replacement for the Armstrong R110000244 and Lennox 13W2201, this 24V control switch manages the timing of heating elements to prevent high inrush current and circuit overloading. This HVAC sequencer relay features a DPST (Double Pole Single Throw) configuration and utilizes a reliable bi-metal thermal disc to ensure consistent blower-on delays and proper cooling cycles, which is vital for maintaining heat exchanger integrity and overall system efficiency.
For contractors servicing Lennox CBX series air handlers or ELO/ELU electric furnaces, this OEM-grade sequencer provides a standard mounting bracket for a fast, drop-in installation. Whether you are troubleshooting a furnace not turning on or addressing staging delays, the 13W22 ensures that electric heat strips energize in the correct sequence. Professionals should verify heat strip amperage and check for signs of burnt spade terminals on the existing unit before installing this 13W22 heat sequencer replacement to ensure long-term operational reliability.
Key Benefits for Technicians:
- Universal Compatibility: Directly replaces Lennox 171-13W22, 13W2201B, and Armstrong R110000244.
- Circuit Protection: Staged activation prevents simultaneous startup of all heating elements, reducing the risk of tripped breakers.
- Standardized Specs: Operates on a 24V circuit at 60Hz with a durable bi-metal construction for light-commercial and residential use.
- Optimized Airflow: Precision-timed delays ensure the blower activates only after elements have reached temperature, avoiding cold drafts.
Common Questions:
How do I know if my heat sequencer is failing?
Common symptoms include heating elements staying energized after the thermostat is satisfied, or specific stages of the electric heat strip failing to turn on. Always check for 24V at the heater coil of the sequencer before condemning the part.
Is the 13W22 interchangeable with R110000244?
Yes, these parts are functionally identical and share the same electrical specifications and footprint for mounting in Lennox and Armstrong equipment.
Can I use this in an air handler with 3 or 4 heat stages?
This is a standard 2-stage sequencer. For systems requiring more stages, multiple sequencers may be wired in tandem. Verify your specific wiring diagram to ensure the staging order matches the original manufacturer specifications.
