Lennox 42W61 Wiring Harness

The Lennox 42W61 Wiring Harness is a critical OEM replacement component designed specifically for heat pump reversing valve assemblies. Engineered for precise electrical continuity, this 36-inch HVAC wire harness facilitates the seamless communication between the defrost control board and the reversing valve solenoid. This ensures the 100273-06 assembly can accurately toggle the refrigerant flow for consistent heating and cooling cycles. Field-tested for compatibility with a wide range of Lennox 13HPD, 13HPX, and 14HPX series units, this harness eliminates the need for field-splicing, maintaining the integrity of the factory electrical schematic. For technicians performing heat pump troubleshooting or valve replacements, utilizing this direct-fit Lennox replacement part ensures low resistance connections and prevents common voltage drop issues that lead to intermittent reversing valve failure. This reversing valve harness is constructed with high-temp insulation to withstand the rigorous conditions of the outdoor cabinet, providing long-term reliability for residential and light commercial split systems.

• Direct OEM Fit: Designed for an exact match to Lennox 100273-06 specifications, ensuring 100% plug-and-play compatibility with existing solenoid connectors.
• Enhanced System Reliability: High-grade heat pump wiring reduces the risk of electrical shorts or signal loss at the reversing valve.
• Simplified Maintenance: Pre-terminated ends and a 3-foot length allow for clean routing and faster physical installation during service calls.
• Broad Model Support: Engineered for use across multiple Lennox-brand equipment generations, including XP14 and XP17 heat pump series.

Is the Lennox 42W61 compatible with non-Lennox heat pumps?
This wiring harness is specifically engineered for Lennox HVAC equipment. While some reversing valve solenoids are universal, the terminal connectors and lead length of the 42W61 are optimized for Lennox equipment grounding and control board layouts.

What are the symptoms of a faulty reversing valve wiring harness?
Technicians often find that a damaged harness causes the heat pump to stay stuck in one mode or chatter during transitions. If you measure 24V at the board but not at the solenoid, the harness requires immediate inspection for breaks or corrosion.

Does this harness include the reversing valve solenoid?
No, the 42W61 is the wiring lead only. If the solenoid coil itself is burnt out, it must be purchased separately to be used in conjunction with this harness.
