Pressure switches prove that the inducer motor has established proper draft before allowing the ignition sequence to proceed. When either switch fails or sticks open, the control board interprets it as a blocked flue or inducer fault, resulting in a no-heat lockout condition — often before you ever see a spark or hear the gas valve open.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Includes HK02ZA395 High Pressure Switch and HK02ZB028 Low Pressure Switch | Factory-calibrated W.C.

Generic replacements frequently carry wider tolerance thresholds, which can cause nuisance lockouts in marginal draft conditions or — more dangerously — fail to detect actual blocked-flue events, creating a safety hazard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Shut off power and gas before beginning. Tools needed: 1\/4\" nut driver, needle-nose pliers, small flathead screwdriver, manometer (recommended to verify switch trip point after installation). Disconnect rubber tubing carefully — inspect hoses for cracks or blockages while the switch is out, as clogged tubing is a common companion failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.

Verify both OEM part numbers (HK02ZA395 and HK02ZB028) against your unit's wiring diagram or data plate before ordering. Replacing both switches together is strongly recommended — if one has failed due to age or moisture exposure, the other is typically at equal risk. Questions about fitment?
