OEM Carrier Dual Run Capacitor 35+5 MFD & Single Run Capacitor 15 MFD 370V for Model PH2PNB024000AC
This listing covers the two factory-specified OEM run capacitors for the Carrier PH2PNB024000AC packaged heat pump unit: the P291-3553 Dual Run Capacitor (35+5 MFD 370V) and the P291-1503 Single Run Capacitor (15 MFD 370V). The dual run capacitor simultaneously supports the compressor (HERM terminal, 35 MFD) and condenser fan motor (FAN terminal, 5 MFD), while the single run capacitor provides dedicated start and run support for auxiliary motor loads. When either capacitor degrades, you'll experience symptoms ranging from a loud hum with no compressor start, a condenser fan that won't spin, or a system that short-cycles and trips on high-pressure lockout within minutes of startup.

-
OEM vs Generic: These are Totaline-branded OEM capacitors built to Carrier factory specification. Generic aftermarket capacitors often carry ±10% MFD tolerance vs. the OEM ±5%, leading to accelerated compressor and motor wear. Always match the MFD rating and use equal or higher voltage rating when replacing.
-
Install Difficulty: 2/5 — Discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Always photograph wiring connections before disconnecting. Note: P291-3553 has been superseded by P291-3554; P291-1503 has been superseded by P291-1504 — both are confirmed compatible replacements.
