Lennox 26W76 (65289200) – Pressure Switch, Actuates at 0.40" W.C.; Resets at 0.55" W.C.
The Lennox 26W76 (part number 65289200) is a factory-authorized pressure switch engineered to monitor and control airflow conditions in gas furnace systems. This switch plays a critical safety role by ensuring proper venting and combustion air before the furnace ignites. It activates (closes) at 0.40" W.C. and resets (opens) at 0.55" W.C., allowing the unit to maintain safe operation by verifying that pressure levels fall within the correct range.
This pressure switch is typically mounted on the inducer housing or flue system, where it monitors negative pressure created by the inducer fan. If airflow is insufficient or obstructed, the switch prevents ignition, protecting the system from overheating or flue gas backdraft.
