OEM Carrier Single Run Capacitor P291-1003 for Model GA2AAD048090ABJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier GA2AAD048090ABJA packaged gas/electric unit. A single run capacitor maintains a continuous phase-shifted current to keep either the compressor or condenser fan motor running at peak efficiency. When this capacitor fails, you'll typically notice symptoms such as a loud humming noise with no motor movement, intermittent shutdowns, hard starts, or a system that trips the breaker shortly after startup — all signs the motor is struggling without proper capacitance support.

  • Specs: Single run capacitor | OEM part number P291-1003 | Factory-matched MFD and voltage rating | Round case design | ±3% tolerance for precise motor protection
  • OEM vs Generic: This is a genuine Carrier OEM component engineered to exact factory specifications. Generic alternatives often carry a ±10% MFD tolerance, which can accelerate motor wear, reduce efficiency, and shorten compressor service life over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, and a multimeter capable of reading capacitance (MFD). Photograph all wiring connections before disconnecting the old capacitor to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed specifically for the Carrier GA2AAD048090ABJA packaged unit. Always verify the MFD and voltage ratings on your existing capacitor's label or the unit's data plate before ordering to confirm an exact match. Not sure if this part fits your system? Our HVAC parts specialists are available to verify fitment before you buy — order with confidence and get back to comfort fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier GA2AAD048090ABJA?
Yes. This is the factory-specified OEM capacitor for the Carrier GA2AAD048090ABJA. 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 GA2AAD048090ABJA?
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.
