Product Details

Description

The Lennox Pressure Switch 0.8" WC is a vital safety component engineered for residential gas furnaces and high-efficiency HVAC systems. Functioning as an air-proving switch, it monitors the draft pressure created by the inducer blower motor to ensure combustion gases are being properly vented. If the system detects insufficient airflow or a blocked vent, this vacuum-actuated switch prevents the furnace from igniting, protecting your home from potential hazards. Calibrated to a precise 0.8-inch water column set point, this replacement pressure switch is essential for troubleshooting furnace ignition failures, pressure switch stuck open errors, and intermittent heating issues. It is a reliable solution for maintaining the safety and efficiency of your heating equipment.
