OEM Carrier Single Run Capacitor P291-1003 for Model GB3AAV048115AEJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier GB3AAV048115AEJA packaged or split-system unit. A single run capacitor provides continuous electrical support to either the compressor or the fan motor during operation — keeping the motor running smoothly and efficiently at its rated speed. When this capacitor weakens or fails, common symptoms include a loud humming noise with no motor movement, the condenser fan spinning slowly or not at all, hard starting under load, or the system tripping on thermal overload and shutting down shortly after startup.

  • Specs: Single run capacitor | OEM part number P291-1003 | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±5% tolerance for precise motor protection
  • OEM vs Generic: This OEM unit is manufactured to Carrier's exact tolerances. Aftermarket single run capacitors frequently fall outside acceptable MFD ranges, causing premature motor wear, reduced efficiency, and shortened compressor or fan motor lifespan — costing far more in the long run.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling — stored charge can cause serious injury. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to confirm discharge. Photograph all wiring connections before removal. Single run capacitors have two terminals; polarity must be observed on polarized types.
  • Warranty: Backed by a 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship the same business day from our climate-controlled warehouse.

Compatibility: Designed and factory-matched for the Carrier GB3AAV048115AEJA. Always cross-reference the MFD and voltage rating printed on your existing capacitor's label or the unit's data plate before ordering to confirm an exact match. Our HVAC parts specialists are available to verify fitment — reach out before you order for complete peace of mind. In stock and ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier GB3AAV048115AEJA?
Yes. This is the factory-specified OEM capacitor for the Carrier GB3AAV048115AEJA. 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 GB3AAV048115AEJA?
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.
