OEM Carrier Single Run Capacitor P291-1503 for Model FC4BNB070010ABAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier FC4BNB070010ABAA fan coil unit. The run capacitor maintains the continuous phase-shifted current needed to keep the blower motor spinning efficiently after startup. When this component fails, you'll notice symptoms such as a humming motor that won't start, a blower that struggles to reach full speed, intermittent shutdowns, or the air handler producing warm air due to reduced airflow across the evaporator coil.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | OEM part number P291-1503 | ±5% tolerance per factory specification
  • OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerances. Aftermarket alternatives often carry ±10% MFD variance, which stresses motor windings over time, shortens blower motor life, and can void equipment warranties. Choose OEM for long-term reliability.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — stored voltage can cause serious injury. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting leads. This is a straightforward swap for a qualified technician or experienced DIYer comfortable with electrical safety procedures.
  • Warranty: Backed by a 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before our same-day shipping cutoff ship from our warehouse the same business day.

Compatibility: Engineered specifically for the Carrier FC4BNB070010ABAA fan coil unit. Always verify the MFD and voltage rating printed on your existing capacitor's label or the unit's data plate before ordering to confirm this is the correct replacement. Our HVAC parts specialists are available to verify fitment — reach out before you order if you have any questions. Order today and get back to comfort fast — in stock and ships same business day.

Frequently Asked Questions

Does this Capacitor fit my Carrier FC4BNB070010ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FC4BNB070010ABAA. 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 FC4BNB070010ABAA?
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.
