Lennox 98M43 Reversing Valve
The Lennox 98M43 Reversing Valve is a critical OEM 4-way control component engineered for high-performance heat pump reversing valve applications. Designed to handle the rigorous demands of R-454B and R-22 systems, this V10 series reversing valve facilitates seamless transitions between heating and cooling cycles by accurately shifting refrigerant flow. This unit comes complete with a pre-installed 24V reversing valve coil, ensuring immediate field compatibility with standard low-voltage control circuits. With a capacity range of 3 to 8.5 tons, the Lennox 98M43 features 7/8" x 1/2" connections, providing a robust fit for a variety of commercial and residential split systems. As a veteran technician knows, maintaining the integrity of the sealed system requires precise hardware; this genuine Lennox replacement part (100145-05) eliminates the guesswork of aftermarket fitment, ensuring your HVAC reversing valve replacement restores the unit to factory specifications for pressure management and cycle efficiency.
Key Benefits- Precision Refrigerant Control: Features a high-integrity slide mechanism to prevent internal bypass and thermal migration.
- Integrated 24V Solenoid: Includes the 24VAC coil for direct integration with the defrost board and thermostat leads.
- Broad Capacity Range: Optimized for systems ranging from 3 to 8.5 tons, offering versatile application across multiple Lennox and Armstrong models.
- OEM Build Quality: Constructed with heavy-duty brass and copper to withstand high discharge temperatures and vibration.
How do I confirm the 98M43 coil is functioning?
With the system energized in the appropriate mode, check for 24V at the solenoid leads. You should hear a distinct "click" as the internal pilot valve shifts. If voltage is present but the slide does not move, the coil or the valve body may be seized.
Does this valve require specific brazing techniques?
Yes. To protect the internal nylon seats and the solenoid, always wrap the valve body in a wet rag or use a heat-blocking putty during the brazing process. Remove the solenoid coil before applying heat to the ports.
Is the 98M43 compatible with newer A2L refrigerants?
This Lennox 98M43 is rated for use in modern systems, including those utilizing R-454B, provided the system's pressure and capacity requirements align with the valve’s 3 to 8.5-ton specification.
