Description
The Lennox 67K32 is an OEM replacement pressure switch engineered to deliver reliable furnace protection and precise airflow monitoring in Lennox heating systems. With a calibrated set point of 0.34″ water column (wc) and a single-pole, single-throw (SPST) switching configuration, this pressure switch accurately detects inducer motor operation and proper venting conditions before allowing the main burner to fire — a critical safety function in modern induced-draft and condensing furnaces.
The 1/4″ barb port connection ensures a secure, leak-free fit to the rubber tubing routed from the inducer housing or collector box, making installation straightforward for HVAC technicians. As a direct OEM replacement, the 67K32 restores factory performance and maintains the integrity of the furnace’s safety control circuit.
