OEM Carrier Pressure Switch HK06WC061 for Model PY4GPAB48130NA

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier PY4GPAB48130NA packaged gas/electric unit. The pressure switch is a normally-open safety device that monitors negative pressure (inches water column) produced by the inducer draft motor. Once the inducer reaches proper speed and draft is confirmed, the switch closes and allows the control board to advance to the ignition sequence. When this switch fails — or when connected tubing cracks or clogs — the board never receives confirmation of safe draft, resulting in a no-heat lockout condition with no ignition attempt.

• Specs: OEM-matched W.C. (inches water column) rating | Single-port design | Factory-calibrated set point | Direct drop-in replacement for HK06WC061
• OEM vs Generic: This is the genuine Carrier OEM part, manufactured to exact factory W.C. tolerances. Aftermarket pressure switches frequently carry wider set-point tolerances, which can cause nuisance trips or — more dangerously — allow operation under unsafe draft conditions.
• Install difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended to verify W.C. after install). Inspect and replace rubber sensing hose if cracked or collapsed before installing new switch.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
