Lennox 72L28 Reversing Valve
The Lennox 72L28 Reversing Valve is an essential OEM replacement part engineered for V2-Series packaged units and residential heat pump systems. Designed to manage the thermodynamic cycle, this 4-way reversing valve facilitates the critical transition between heating and cooling modes by redirecting refrigerant flow based on system demand. Built with a 24V coil and standard sweat connections, it ensures seamless integration with Lennox HVAC equipment, specifically targeting refrigerant flow control in air-source systems.
For technicians in the field, the 72L28 offers a robust construction capable of handling 50/60 Hz frequencies. This HVAC reversing valve is purpose-built to maintain high-pressure stability, preventing internal bypass leaks that often lead to compressor inefficiency. Whether you are performing a reversing valve replacement during a winter heating failure or a summer cooling service call, this genuine component guarantees the precise orifice alignment and sliding block movement required for high-performance heat pump repair.
Key Benefits- OEM Compatibility: Precision-fit for Lennox V2-Series and compatible heat pump models to eliminate field modifications.
- Enhanced Flow Dynamics: Optimized internal design minimizes pressure drops across the valve body during refrigerant reversal.
- Reliable Actuation: The included 24V coil provides consistent magnetic force for reliable pilot valve operation in all weather conditions.
- Durability: High-grade materials resist corrosion and withstand the thermal stresses of frequent cycle switching.
- What are the symptoms of a stuck Lennox 72L28 valve? Common signs include the system being "stuck" in one mode, lukewarm air output, or equalized pressures on the high and low sides while the compressor is running.
- Does this valve work with both R-22 and R-410A? While specifically designed for Lennox equipment, always verify the maximum operating pressure (MOP) on the unit nameplate, as R-410A systems operate at significantly higher pressures than older R-22 units.
- Is the solenoid coil included with the 72L28? Yes, this assembly typically includes the 24V solenoid coil necessary for electronic actuation from the defrost board or thermostat.
