Lennox 77W95 Motor Actuator 318172-701 This bi-metal TXV kit functions

This bi-metal TXV kit functions as a thermostatic expansion valve

Critical Safety Protection: Open-on-rise SPST contact arrangement prevents overheating and potential fires by interrupting the combustion circuit

and residential AC systems that are struggling to turn over or clearing "stalled motor" faults

It is best practice to install a new 5uF 370V capacitor when replacing any PSC blower motor to ensure the system operates within nameplate amperage

Built to withstand the harsh thermal environments of gas furnaces

Lennox 77W95 Motor Actuator 318172-701 This bi-metal TXV kit functionsThe Lennox 77W95 Motor Actuator is a critical OEM component designed for high precision control within commercial and industrial HVACR systems. Operating on a versatile 24VAC VDC power supply at 50 60Hz, this non spring return actuator (part number 102899 01) is engineered to convert electronic signals into mechanical motion for the exact positioning of dampers and valves. It serves as a direct replacement for the legacy 14V61 (102899 02) model,
