Description

  • The Lennox 56L3201 HVAC Furnace Flue Inducer Pressure Switch is an industrial-grade, commercial-grade equipment component engineered specifically to ensure continuous negative pressure safety monitoring across demanding residential gas furnace heating arrays.
  • Fabricated from premium galvanized steel housing components and high-temperature silicone diaphragms, this high-performance component handles tight pressure safety thresholds at a strict -0.55" WC setpoint with repeatable snap-action logic while permanently resisting internal diaphragm fatigue and premature mechanical contact failure.
  • The innovative dual-port sensing design significantly improves diagnostic accuracy to smoothly handle combustion fan operation monitoring without causing nuisance control ignition lockouts or blocked flue sensor failure codes.
  • Ideal for licensed HVAC/R technicians, mechanical contractors, and facility maintenance supervisors, this durable safety switch features an integrated multi-hole mounting bracket and standard spade connectors to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive equipment failure callbacks.
