OEM Carrier Single Run Capacitor 25 MFD 440V for Model 09DE109C900

This is the factory-specified OEM replacement single run capacitor for the Carrier 09DE109C900. The run capacitor stores and releases the electrical charge needed to start and sustain the blower or condenser fan motor during operation. When this capacitor begins to fail, you may notice the motor running noisily, overheating unexpectedly, or refusing to start altogether — leaving your system unable to cool or heat effectively.

• Specs: 25 MFD (microfarad) | 440V rated | Oval aluminum case | 50/60 Hz | Dimensions: 1.8" L × 2.8" W × 2.9" H | Operating range: -40°C to +70°C
• OEM vs Generic: This is a genuine Carrier OEM part (P291-2504) built to factory-exact ±3% MFD tolerance. Generic capacitors frequently run ±10% or more, increasing motor stress and shortening system lifespan. For a long-term fix, OEM is the right choice.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify charge is clear). Photograph all wiring connections before disconnecting.
• Warranty: 1-year OEM manufacturer warranty. Orders placed before cutoff ship same business day from our warehouse.
