OEM Carrier SPST Pressure Switch High Fire — HK06WC091 / HK06WC092 for Model PG8JVA060110AAJA

This OEM Carrier SPST (Single-Pole, Single-Throw) high-fire pressure switch is the factory-specified replacement for the Carrier PG8JVA060110AAJA gas furnace. The pressure switch proves that the draft inducer motor is running at the correct RPM and generating sufficient negative pressure before allowing ignition to proceed. When this switch fails or sticks open, the furnace will lock out before it ever reaches the ignition stage — often displaying a fault code for a pressure switch fault or inducer fault. Available as two variants: HK06WC091 (switch only) and HK06WC092 (switch with pressure tube included).

• Specs: SPST (Single-Pole, Single-Throw) configuration | High-fire pressure switch | Factory Authorized Part manufactured by Honeywell for Carrier | Compatible with Carrier, Bryant, and Payne gas furnace platforms
• OEM vs Generic: This is a genuine OEM part engineered to exact W.C. (water column) trip-point tolerances. Aftermarket pressure switches frequently carry ±15% pressure rating tolerances, which can cause nuisance lockouts or — more dangerously — allow the furnace to operate with inadequate flue draft.
• Install difficulty: 2/5 — Straightforward swap accessible from the furnace cabinet. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, multimeter (to test switch continuity). Always power down and verify the inducer hose is free of cracks or blockages before installing the new switch — a clogged hose is the #1 cause of pressure switch failure.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8JVA060110AAJA gas furnace. Order HK06WC091 if your existing pressure tube is intact; order HK06WC092 if your pressure tube is cracked, brittle, or missing. Verify your existing switch's W.C. rating on the data plate or switch body before ordering. Questions about fitment? Our HVAC parts specialists confirm compatibility before you buy.
