OEM Carrier Single Run Capacitor P291-1503 for Model FF1ENE036005AAAA

This is the factory-specified OEM single run capacitor (part number P291-1503) for the Carrier FF1ENE036005AAAA fan coil unit. A run capacitor provides the continuous phase-shifted current needed to keep a single-phase motor running efficiently after startup. When this capacitor weakens or fails, you may notice the motor struggling to start, humming without turning, drawing excess current, or the system shutting down on thermal overload shortly after cycling on. Replacing it promptly protects the motor from burnout and restores efficient, reliable operation.

  • Specs: Single run capacitor | Factory-matched MFD rating and voltage | Round or oval case per OEM spec | ±3% tolerance for precision motor protection — verify exact MFD and voltage on your unit's data plate before ordering
  • OEM vs Generic: This is a genuine OEM Carrier part, not an aftermarket substitute. OEM capacitors are manufactured to exact factory tolerance, ensuring proper motor run current and longer service life. Generic capacitors often carry a ±10% MFD tolerance, which can accelerate winding wear and reduce equipment lifespan.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, and a multimeter for verification. Photograph all wiring connections before disconnecting terminals to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier FF1ENE036005AAAA fan coil unit using OEM part number P291-1503. Always confirm the MFD rating and voltage stamped on your existing capacitor or listed on the unit's data plate before ordering to ensure a proper fit. Have a question about fitment? Our HVAC parts specialists verify compatibility before you buy — reach out before placing your order.

Frequently Asked Questions

Does this Capacitor fit my Carrier FF1ENE036005AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FF1ENE036005AAAA. 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 FF1ENE036005AAAA?
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?
