OEM Carrier Single Run Capacitor P291-1003 for Model GB1AAV048135AEJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier GB1AAV048135AEJA packaged gas/electric unit. A run capacitor provides the continuous phase-shifted current necessary to keep the condenser fan motor or compressor running efficiently after startup. When this capacitor weakens or fails, you may notice a loud humming noise with no motor movement, intermittent short-cycling, higher-than-normal energy bills, or a complete failure of the fan or compressor to run — any of which can quickly cascade into compressor damage if left unaddressed.

  • Specs: Single run capacitor | OEM part number P291-1003 | Factory-matched MFD and voltage rating | Round or oval case per original spec | ±5% tolerance for precision motor protection
  • OEM vs Generic: This is a genuine OEM Carrier capacitor engineered to exact factory tolerances. Generic aftermarket capacitors frequently fall outside acceptable MFD ranges (±10% or worse), placing unnecessary stress on motors and compressors and voiding equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools required: 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed specifically for the Carrier GB1AAV048135AEJA packaged unit. Always verify the MFD and voltage rating printed on your existing capacitor against your unit's data plate before ordering. Not sure if this is the right part? Our HVAC parts specialists are available to confirm fitment before you buy — order with confidence and get your system back up and running today.

Frequently Asked Questions

Does this Capacitor fit my Carrier GB1AAV048135AEJA?
Yes. This is the factory-specified OEM capacitor for the Carrier GB1AAV048135AEJA. 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 GB1AAV048135AEJA?
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.
