OEM Carrier Single Run Capacitor 50 MFD 370V for Model 09DK034100

This OEM single run capacitor is the factory-specified replacement for the Carrier 09DK034100, carrying OEM part number P291-5003. The run capacitor maintains a continuous phase-shifted current to keep the compressor motor spinning efficiently after startup. When this component degrades or fails, you'll typically notice the compressor humming without starting, the system tripping on thermal overload, rising energy bills from motor inefficiency, or a complete no-cool condition. Replacing it promptly prevents costly compressor damage.

• Specs: 50 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | Non-PCB dielectric fluid | UL recognized
• OEM vs Generic: This OEM P291-5003 capacitor is manufactured to Carrier's exact factory tolerances. Generic aftermarket units often run at wider MFD variance (±10% or more), which accelerates compressor winding wear and shortens overall system life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to verify the replacement. Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty included. Ships same business day from our warehouse when ordered before cutoff.
