OEM Carrier Single Run Capacitor P291-0753 for Model UPFLOW150U4819X

This OEM single run capacitor (part number P291-0753) is the factory-specified replacement for the Carrier UPFLOW150U4819X upflow air handler system. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency after startup. When this capacitor degrades or fails, you'll notice symptoms such as a humming motor that won't spin up, intermittent blower operation, warm air from supply registers, or a system that trips on thermal overload and shuts down shortly after starting.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | ±5% OEM tolerance — verify your unit's data plate for exact MFD value before ordering
  • OEM vs Generic: This is a genuine OEM Carrier part (P291-0753), manufactured to exact factory specifications. Generic alternatives often carry a looser ±10% MFD tolerance, which accelerates motor winding wear and can shorten blower motor life significantly over time.
  • Install Difficulty: 2/5 — Always shut off power at the breaker and discharge the capacitor terminals before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back online fast.

Compatibility: Designed for the Carrier UPFLOW150U4819X upflow air handler. Always cross-reference the MFD rating and voltage stamped on your existing capacitor or the unit's data plate to confirm fitment. Our parts specialists are available to verify compatibility before you order — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier UPFLOW150U4819X?
Yes. This is the factory-specified OEM capacitor for the Carrier UPFLOW150U4819X. 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 UPFLOW150U4819X?
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.
