OEM Carrier Single Run Capacitor P291-1003 for Model PG8JAA042090ADJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8JAA042090ADJA packaged gas unit. The run capacitor maintains a continuous phase-shifted current to the blower or condenser fan motor, keeping it spinning efficiently at full torque after startup. When the capacitor degrades or fails, you'll notice symptoms like a humming motor that won't turn over, a fan that spins slowly or only when manually assisted, or a unit that trips on high-limit and short-cycles due to reduced airflow caused by an underperforming blower motor.

  • Specs: Single run capacitor | Factory-matched MFD and voltage rating | Cylindrical case | OEM-grade ±5% tolerance for precise motor protection
  • OEM vs Generic: This is a genuine Carrier OEM part (P291-1003), manufactured to exact factory specifications. Generic capacitors often carry a wider ±10% MFD tolerance, which can reduce motor efficiency, increase heat buildup, and shorten motor life over time.
  • Install Difficulty: 2/5 — A straightforward replacement suitable for experienced DIYers and technicians alike. Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier PG8JAA042090ADJA packaged gas unit. Before ordering, verify the MFD and voltage ratings printed on your existing capacitor against the data plate on your unit to confirm an exact match. Our HVAC parts specialists are available to verify fitment before you order — order with confidence and get your system back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA042090ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA042090ADJA. 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 PG8JAA042090ADJA?
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.
