OEM Carrier Furnace Pressure Switch Replacement for PH13PB060000AAAA

The pressure switch is a critical safety device in your Carrier furnace that confirms the inducer (draft) motor is moving combustion gases before the board allows the igniter and gas valve to fire. It senses negative pressure through a small rubber hose; if proper draft isn't detected, it keeps the system locked out to prevent dangerous flue-gas spillage. When the switch fails or sticks, homeowners see the furnace try to start, run the inducer, then shut down without igniting — often repeating in a frustrating short-cycle. A flashing 'pressure switch' fault code, no heat on the coldest days, and a furnace that 'clicks but won't light' are the classic signs. This is a normally-open diaphragm switch with a defined trip set-point measured in inches of water column (in. W.C.), a single- or dual-port body, and a specific hose-barb orientation. The set-point and port count must match your furnace's draft design exactly. A blocked hose, cracked nipple, or clogged condensate trap can mimic a bad switch, so verify draft before replacing. OEM matters because the calibrated trip pressure is the whole point of the part. Generic switches frequently carry wider tolerances and looser set-points; one that trips at the wrong pressure will either nuisance-lockout a healthy furnace or, worse, allow ignition without adequate draft. The genuine Carrier switch holds the tight factory calibration your unit's safety certification depends on. Installation difficulty: 2 of 5. Tools needed: 1/4" nut driver, Phillips screwdriver, and a multimeter to confirm continuity on a draft call. #1 safety warning: shut off both the electrical breaker and the gas supply to the furnace before servicing. Inspect the hose for cracks and moisture while you're in there. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
