This dual-function switch monitors both the low- and high-fire draft states of the inducer, proving safe venting before the ignition sequence can proceed. If your furnace locks out, short-cycles, or throws a pressure-switch fault code, a failed or drifting switch is a common culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Combination (dual) negative-pressure switch\u003c\/li\u003e\n\u003cli\u003eSet points: -.30 in.

Generic or universal switches often ship with a single set point or mismatched pressure calibration, which can cause nuisance lockouts or bypass a critical safety. For a modulating furnace, matching both set points is essential to correct low\/high-fire operation.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — a competent DIYer can complete the swap in 15–30 minutes with basic hand tools.
