OEM Carrier Single Run Capacitor P291-1003 for Model FC4BNF030015AEAA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier FC4BNF030015AEAA fan coil unit. The run capacitor provides the continuous phase-shifted current required to keep the blower motor spinning efficiently after startup. When this capacitor degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin, sluggish blower startup, intermittent shutdowns, or a complete loss of airflow — all signs of a capacitor that can no longer hold its rated charge.

• Specs: Single run capacitor | Factory-rated MFD and voltage per OEM specification | Oval or round case (verify data plate) | ±5% tolerance to match original factory performance
• OEM vs Generic: This is a genuine OEM Carrier part, manufactured to exact factory tolerances. Generic replacements often carry ±10% MFD variance, which accelerates motor winding wear and can shorten the service life of your blower motor significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Recommended tools: 1/4" nut driver, insulated needle-nose pliers, and a multimeter capable of MFD testing. Photograph all wiring connections before disconnecting the old capacitor.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. Orders placed before our same-day shipping cutoff ship from our warehouse the same business day — minimizing your system downtime.

Compatibility: Designed specifically for the Carrier FC4BNF030015AEAA fan coil unit. Before ordering, confirm the MFD rating and voltage printed on your existing capacitor or unit data plate to ensure a proper match. Our HVAC parts specialists are available to verify fitment before you complete your purchase — no guesswork required.
