OEM Carrier Pressure Switch HK06WC091 for Model PG8JEA060110AAJA

This is the genuine OEM replacement pressure switch for the Carrier PG8JEA060110AAJA packaged gas furnace. The pressure switch is a critical safety component that monitors negative air pressure produced by the draft inducer blower. Once the inducer reaches proper speed and airflow, the pressure switch closes — proving safe venting conditions and signaling the control board to proceed with ignition. A failed pressure switch will prevent the furnace from ever reaching the ignition stage, resulting in a no-heat lockout condition. Common symptoms include the inducer running continuously with no ignition, a blinking fault code on the control board, or the system cycling off immediately after startup.

• Part Number & Specs: OEM Part HK06WC091 | Factory-calibrated W.C. (water column) rating | Single-port hose connection | Designed for the draft inducer on Carrier PG8JEA060110AAJA packaged units
• OEM vs Generic: This OEM switch is calibrated to the exact pressure differential specified by Carrier engineering. Aftermarket pressure switches frequently carry wider tolerances that can cause nuisance lockouts or, worse, fail to detect unsafe flue conditions — a serious safety risk in any gas appliance.
• Install Difficulty: 2/5 — Straightforward swap once the unit is de-energized. Tools needed: 1/4" nut driver, flat-head screwdriver, and a short length of replacement hose (inspect existing hose for cracks). Always verify the hose fitting is fully seated and the electrical connector clicks into place before restoring power.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered and factory-matched for the Carrier PG8JEA060110AAJA packaged gas furnace.
