OEM Carrier Single Run Capacitor 30 MFD 440V for Model 09DE109C100

This OEM single run capacitor (Carrier part number P291-3004) is the factory-specified replacement for the Carrier 09DE109C100. The run capacitor provides the phase-shifted electrical charge that keeps the motor running at peak efficiency after startup. When a single run capacitor degrades or fails, symptoms include the motor humming but not spinning, the unit short-cycling, overheating trips, or a complete no-start condition — often during the hottest days of the year when you need cooling most.

• Specs: 30 MFD (microfarad) | 440V rated | Oval case | ±5% factory tolerance | 50/60 Hz compatible | Non-PCB dielectric fluid | UL-approved current interrupter
• OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor — manufactured to exact factory specifications. Generic capacitors often carry ±10% MFD tolerance, which accelerates motor winding wear and reduces compressor lifespan over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use an insulated screwdriver across terminals). Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Capacitor terminals are typically marked HERM, FAN, and COM.
• Warranty: 1-year OEM factory warranty included. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for Carrier model 09DE109C100. Always verify the MFD rating and voltage printed on your existing capacitor's data label before ordering — using an incorrect MFD value can damage the motor. Questions about fitment?
