OEM Carrier Single Run Capacitor P291-1503 for Model FH4ANA004000AAAA

This is the factory-specified OEM single run capacitor (part number P291-1503) for the Carrier FH4ANA004000AAAA fan coil unit. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running smoothly and efficiently. When this component fails, common symptoms include a humming motor that won't spin up, intermittent shutdowns, reduced airflow, or a blower that draws excessive amperage and trips the breaker. Replacing it promptly prevents secondary damage to the motor windings.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case design | OEM part number P291-1503 | ±5% tolerance per factory spec
  • OEM vs Generic: This is a genuine Carrier OEM capacitor — not an aftermarket substitute. Generic capacitors often carry a ±10% MFD tolerance, which causes motor strain, overheating, and premature failure. OEM ensures the exact electrical characteristics your Carrier fan coil was engineered to use.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter for confirmation, and a discharge resistor or insulated tool. Photograph all wiring connections before disconnecting the old unit.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for the Carrier FH4ANA004000AAAA fan coil unit. Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit data plate before ordering to confirm an exact match. Need help verifying fitment?

Frequently Asked Questions

Does this Capacitor fit my Carrier FH4ANA004000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FH4ANA004000AAAA. 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 FH4ANA004000AAAA?
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.
