OEM Carrier Pressure Switch with Bracket — -0.27" WC for Model PG8JEB036045AAJA

This OEM pressure switch with bracket is the factory-specified replacement for the Carrier PG8JEB036045AAJA gas furnace. The inducer pressure switch monitors negative pressure created by the draft inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board cannot verify inducer operation and will lock out the heating cycle entirely — leaving you with no heat and often a blinking fault code indicating a pressure switch fault.

• Specs: -0.27" W.C. Break (open) | 0.42" W.C. Max Make (close) | SPST configuration | Includes factory mounting bracket | OEM Part# HK06WC100, superseded by HK06MC100 | Cross-references: IS20205-6117, ICP 1191249
• OEM vs Generic: OEM pressure switches are calibrated to exact W.C. tolerances at the factory. Off-spec generic switches can trip prematurely or fail to close, causing nuisance lockouts or unsafe ignition sequences. Don't gamble with a safety-critical component.
• Install difficulty: 2/5 — Shut off power and gas to the furnace before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers. Disconnect the rubber hose and two-wire harness from the old switch, transfer the bracket if reusing, and snap the hose and harness onto the new switch. Always inspect the pressure hose for cracks or blockage before install.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.
