OEM Carrier Single Run Capacitor P291-1003 for Model FC4BNF036005ABAA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier FC4BNF036005ABAA fan coil unit. A single run capacitor maintains the continuous phase-shifted current needed to keep your blower or fan motor running at peak efficiency. When this component fails, you'll typically notice symptoms such as a humming sound with no motor movement, intermittent shutdowns, or a blower fan that refuses to start — leaving your system unable to circulate conditioned air through your home.

  • Specs: OEM-matched MFD rating | 370V/440V rated (verify on unit data plate) | Oval or round case | Factory ±3% capacitance tolerance for precise motor protection
  • OEM vs Generic: This is a genuine OEM Carrier part, engineered to exact factory specifications. Aftermarket alternatives commonly ship with ±10% MFD tolerances, which stresses motor windings over time and can shorten blower motor life significantly.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — stored voltage can cause serious injury. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed specifically for the Carrier FC4BNF036005ABAA fan coil unit. Always confirm the MFD rating and voltage printed on your existing capacitor or unit data plate before ordering to ensure a correct fit. Have questions about fitment? Our HVAC parts specialists verify compatibility before your order ships — reach out via chat or phone for fast assistance.

Frequently Asked Questions

Does this Capacitor fit my Carrier FC4BNF036005ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FC4BNF036005ABAA. 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 FC4BNF036005ABAA?
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.
