OEM Carrier Single Run Capacitor 5 MFD 370V for Model PG9MAB036060LBSA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAB036060LBSA gas furnace. The run capacitor provides the sustained electrical charge required to keep the indoor blower motor running at full efficiency. When this capacitor degrades or fails, the blower motor may struggle to start, run intermittently, overheat, or stop altogether — resulting in poor airflow, uneven heating, or a system lockout fault. Replacing a failing run capacitor promptly protects the blower motor from burnout and avoids a far more costly repair.

• Specs: 5 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | 50/60 Hz | OEM Part # P291-0503 (superseded by P291-0504) | Cross-references: P2910503, 97F5705
• OEM vs Generic: This OEM-spec capacitor is manufactured to exact Carrier factory tolerances (±5% MFD). Generic aftermarket capacitors often carry a wider ±10% tolerance, which accelerates blower motor wear and can shorten motor life — especially in high-run-time furnace applications.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify discharge and confirm MFD rating). Photograph all wiring connections before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAB036060LBSA gas furnace indoor blower motor circuit. Always verify the MFD and voltage rating on your existing capacitor's data label before ordering. Cross-reference OEM part numbers P291-0503 and P291-0504. Need help confirming fitment?
