OEM Carrier Single Run Capacitor P291-1003 for Model FC4BNF033000ABAA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier FC4BNF033000ABAA fan coil unit. A single run capacitor provides the continuous phase-shifted current needed to keep the blower motor running efficiently after startup. When this capacitor weakens or fails, common symptoms include a humming motor that won't spin, intermittent blower operation, the system tripping on thermal overload, or reduced airflow that causes the coil to freeze. Replacing this component promptly prevents secondary damage to the blower motor itself.

  • Specs: OEM-matched MFD rating | 370V rated | Designed for single-motor fan coil blower application | Factory ±5% tolerance for reliable, long-term motor performance
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory tolerances. Aftermarket alternatives frequently ship with ±10% MFD variance, which shortens blower motor life, reduces efficiency, and may void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. Turn off all power at the breaker and air handler disconnect before beginning.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed by 3 PM ship the same business day from our stocked warehouse — no backorder delays.

Compatibility: Engineered specifically for the Carrier FC4BNF033000ABAA fan coil unit. Always confirm the MFD rating and voltage on your existing capacitor's label or unit data plate before ordering to ensure a correct fit. Not sure? Our HVAC parts specialists verify fitment before you buy — contact us anytime.

Frequently Asked Questions

Does this Capacitor fit my Carrier FC4BNF033000ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FC4BNF033000ABAA. 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 FC4BNF033000ABAA?
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.
