Lennox 67K19 Relay
The Lennox 67K19 Relay (part number 67K1901) is an essential OEM replacement component engineered for high-reliability switching in residential and commercial HVAC systems. This 120V relay is typically configured for SPDT (Single Pole Double Throw) or SPST (Single Pole Single Throw) operation, depending on the specific furnace or air handler wiring requirements. Operating at 50/60 Hz, it provides precise control over high-voltage circuits for components like blower motors, condensing units, and combustion fans based on low-voltage signals from the thermostat or control board.
For service technicians, the 67K1901 relay offers a direct-fit solution that eliminates the mounting and terminal alignment issues common with universal "will-fit" parts. Its compact footprint is ideal for tight electrical cabinets in Lennox air handlers and furnaces. Utilizing a genuine Lennox 67K19 ensures the electrical timing and contact ratings meet the original manufacturer specifications, preventing premature failures in the field and maintaining system efficiency during high-demand cycles.
Key Benefits for Contractors:
- OEM Compatibility: Precision-matched for Lennox 67K1901 specifications to ensure seamless integration with existing wiring harnesses.
- Heavy-Duty Contacts: Designed to handle the inductive loads of 120V HVAC motors and solenoids without excessive pitting or sticking.
- Versatile Configuration: Functionally supports SPDT switching for complex control logic or standard SPST applications.
- Broad Application: A common HVAC control relay used across multiple generations of Lennox heating and cooling equipment.
- Reliable Performance: Engineered for millions of cycles, ensuring long-term stability in HVAC electrical systems.
Common Questions:
Can the 67K1901 relay replace a generic 120V relay?
While universal relays exist, using the Lennox 67K19 OEM relay is recommended to ensure the footprint and terminal designations match the factory wiring diagram, preventing installation errors.
What are the symptoms of a failing HVAC relay?
Common signs include a "clicking" sound without the component starting, a blower motor that runs constantly (stuck closed), or a furnace that fails to initiate the heating cycle (stuck open).
Is this relay compatible with 240V systems?
No, this specific model is rated for 120V primary voltage. Always verify the voltage requirements on your unit’s data plate before installation.
