OEM Carrier Single Run Capacitor 50 MFD 370V for Model 09DK024100

This OEM single run capacitor (part number P291-5003) is the factory-specified replacement for the Carrier 09DK024100. The run capacitor remains continuously energized during motor operation, providing the phase-shifted current needed to keep the compressor running smoothly and efficiently. When this capacitor weakens or fails, symptoms include a loud humming sound with no motor startup, the compressor short-cycling within minutes of starting, noticeably reduced cooling output, or a complete no-start condition that leaves your system dead on a hot day.

• Specs: 50 MFD (microfarad) | 370V rated (440V compatible — higher voltage is an acceptable upgrade) | Single run capacitor | Factory ±5% tolerance | Oval metal can design
• OEM vs Generic: This OEM Carrier P291-5003 capacitor is built to exact factory tolerances. Generic aftermarket capacitors often drift ±10% MFD over time, accelerating compressor wear and reducing system efficiency. OEM ensures a drop-in fit with no guesswork.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling — use a resistor or insulated screwdriver across the terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. Average install time: 15–20 minutes.
• Warranty: 1-year OEM factory warranty included. Orders placed by 3 PM ship same business day from our warehouse.

Compatibility: Designed for Carrier model 09DK024100. Always verify the MFD rating and voltage stamped on your existing capacitor's label before ordering — specs can vary by production run. Not sure? Our HVAC parts specialists verify fitment before you buy. Order today and get back to cool fast.
