OEM Carrier Dual Run Capacitor 35+5 MFD 370V for Model PH1ZNA024000ADAA

This OEM dual run capacitor kit covers both the P291-3553RS (Dual Run, 35+5 MFD 370V Round) and the P291-1503 (Single Run, 15 MFD 370V Oval) — the two factory-specified capacitors for the Carrier PH1ZNA024000ADAA heat pump system. The dual run capacitor simultaneously serves the compressor (HERM terminal) and the condenser fan motor (FAN terminal), while the single run capacitor supports the blower or auxiliary motor circuit. When either capacitor fails, you'll typically hear a low hum with no motor start, notice the system short-cycling within minutes of startup, or experience full system lockout with no cooling or heating output.

• Primary Specs (P291-3553RS Dual Run): 35+5 MFD (microfarad) | 370V rated | Round case | Three terminals: HERM – C – FAN | Factory GE/Genteq manufactured for Carrier | ±5% tolerance
• Secondary Specs (P291-1503 Single Run): 15 MFD | 370V rated | Oval case | Factory Totaline/Carrier OEM | Note: superseded by P291-1504 (440V upgrade); 440V is backward-compatible with 370V systems
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances. Generic units commonly run ±10% MFD deviation, accelerating motor winding stress, reducing compressor life, and voiding equipment warranties on newer systems.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling — stored charge can cause injury. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph existing wiring before disconnecting. Match MFD rating exactly; voltage rating must be equal to or higher than the original.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
