OEM Carrier Single Run Capacitor P291-1503 for Model FC4BNF048010ACAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier FC4BNF048010ACAA fan coil unit. A single run capacitor maintains a continuous phase shift to keep the blower motor running at peak efficiency after startup. When this capacitor fails, you'll notice symptoms such as a humming motor that won't spin, intermittent blower operation, weak airflow, or the system shutting down shortly after startup due to motor overload. Replacing a failed capacitor promptly protects the blower motor from heat damage and costly secondary failures.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Round or oval case | ±5% OEM tolerance for precise motor protection
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory specifications. Generic aftermarket capacitors often carry ±10% MFD tolerance, which accelerates motor winding wear and can void equipment warranties — OEM is always the safer choice for fan coil applications.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to confirm discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our stocked warehouse — no waiting on backorders.

Compatibility: Designed specifically for the Carrier FC4BNF048010ACAA fan coil unit. Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility before you buy — reach out with your model and serial number for peace of mind. Order today and ship today — get your system back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier FC4BNF048010ACAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FC4BNF048010ACAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Carrier FC4BNF048010ACAA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
