When failures in the heating cycle occur

Critical Safety Protection: Monitors internal plenum temperatures to prevent heat exchanger damage

Optimal Evaporation: The specialized clay coating facilitates consistent wicking and prevents water from "beading" on the aluminum surface

ensuring a seamless drop-in fit for legacy Wayne combustion systems

Lennox 93J54 Temperature Sensor When failures in the heatingThe Lennox 93J54 Temperature Sensor is a critical OEM 10k Ohm thermistor designed for precision ambient air monitoring in high performance HVACR systems. As a genuine Lennox 93J5401 replacement part, this sensor provides the control board with real time analog voltage data to manage heating and cooling cycles, ensuring the unit operates within its engineered thermal parameters. Measuring roughly 3. 45" x 4. 15", this Lennox ambient temperature sensor
