OEM Carrier Single Run Capacitor P291-1503 for Model FC4BNF036000AEAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier FC4BNF036000AEAA fan coil unit. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency. When it begins to fail, you may notice the blower motor struggling to start, humming without spinning, overheating, or shutting down shortly after startup — all signs of a capacitor that can no longer hold its charge.

  • Specs: Single run capacitor | Factory-matched MFD rating | Rated voltage per OEM specification | Oval or round case per original design | ±3% tolerance for precision motor protection
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory tolerances. Generic aftermarket capacitors frequently carry a ±10% MFD variance, which accelerates motor winding wear, reduces efficiency, and shortens the service life of your blower motor significantly.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, and a multimeter capable of reading capacitance. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed by cutoff time ship the same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Carrier FC4BNF036000AEAA fan coil unit. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor before placing your order. Our parts specialists are available to confirm fitment — reach out before you buy if you have any questions. Order today and get back to comfort fast with same-day shipping available.

Frequently Asked Questions

Does this Capacitor fit my Carrier FC4BNF036000AEAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FC4BNF036000AEAA. 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 FC4BNF036000AEAA?
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.
