Lennox 22W04 Blower Relay
As a field-tested HVAC blower relay replacement, the Lennox 22W04 is a critical component for managing indoor blower motor operations. This Double Pole Single Throw (DPST) relay is engineered to handle high-power hardware sequences using low-power 24V thermostat signals. Whether you are troubleshooting an air handler blower motor that won't engage or a furnace that stays on after the call for heat has ended, this OEM part provides the precise switching required for Lennox HVAC systems. Crucially, the 22W04 is 100% interchangeable and identical to the Lennox 22W0401, ensuring a direct-drop fit in various rooftop units and residential air handlers. Its 12-amp rated contacts and robust construction are built to withstand the rigors of frequent cycling in commercial and residential applications, maintaining system efficiency and protecting other sensitive control board electronics.
Key Benefits for Technicians:- Direct OEM Compatibility: Verified as a factory-authorized Lennox 22W04 replacement, eliminating mounting and wiring complications during field service.
- DPST Configuration: Features Double Pole Single Throw capability, allowing for the simultaneous switching of two separate high-voltage circuits.
- Enhanced Reliability: Built with heavy-duty contacts to prevent pitting and sticking, common failure points in generic aftermarket relays.
- Versatile Application: Frequently used in Lennox RHP13, ELO183, and OHR25 series units for reliable blower sequence control.
- Verified Equivalent: Fully substitutes the 22W0401, providing flexibility in inventory management and part sourcing.
Is the Lennox 22W04 a direct replacement for the 22W0401?
Yes. These parts are technically identical. The 22W04 and 22W0401 share the same electrical specifications and physical footprint, making them interchangeable in all documented Lennox applications.
What are the primary symptoms of a failing blower relay?
Technicians typically look for a blower motor that fails to start despite receiving a signal from the control board, or a "stuck" blower that runs continuously. Measuring for 24VAC across the coil without the DPST contacts closing is a definitive diagnostic indicator.
Can I use this relay for both heating and cooling blower speeds?
The 22W04 is designed to activate the blower circuit. Depending on your specific wiring diagram, it may control a single speed or interface with a multi-speed board to trigger high-speed cooling or medium-speed heating airflow.
