Lennox 72W95 Temp Switch

The Lennox 72W95 is a critical F58-29F Freezestat Temp Switch engineered for industrial and commercial refrigeration monitoring. Designed specifically to prevent evaporator coil freeze-up, this HVAC temperature control switch triggers an automated response when sensing temperatures between 58°F and 29°F. This OEM Lennox part (also identified as Lennox 102450-01) ensures that air conditioning systems and heat pumps maintain thermal integrity during low-ambient operations, effectively protecting the compressor and heat exchanger from slugging or ice-related mechanical failure.

For service technicians, the Lennox 72W95 Freezestat offers a compact form factor for versatile mounting in restricted cabinets. It is a direct internal replacement for Lennox KCA092 and KCA102 series units. By utilizing high-accuracy thermal sensing, this limit switch reduces unnecessary system downtime and mitigates the risk of catastrophic coil ruptures. The durable construction is optimized for the high-vibration and moisture-heavy environments typical of commercial rooftop units and split systems.

• Evaporator Coil Protection: Actively monitors for freezing conditions to prevent ice buildup and airflow restriction.
• Precision Thermal Sensing: Accurate setpoints between 58°F and 29°F ensure the unit shuts down before refrigerant temperatures reach critical lows.
• OEM Compatibility: Exact replacement for Lennox 102450-01, ensuring seamless integration with existing control boards and wiring harnesses.
• Durable Construction: Engineered to withstand the harsh environmental stresses and temperature fluctuations found in commercial HVACR applications.

• What models are compatible with the 72W95? This freezestat is commonly used in Lennox KCA092H4, KCA092S4, KCA102H4, and KCA102S4 commercial units.
• How does this part prevent system damage? When the temperature drops below the preset limit, the switch breaks the control circuit to stop the cooling cycle, allowing the coil to thaw and preventing liquid refrigerant from returning to the compressor.
• Can this be used as a general-purpose limit switch? While it functions as a thermal limit, it is specifically calibrated for freeze protection; we recommend cross-referencing your technician manual to ensure the 58-29F range matches your system requirements.
