OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA048110ABJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA048110ABJA packaged gas/electric unit. The run capacitor provides the continuous phase-shifted current necessary to keep the blower or condenser fan motor running at peak efficiency. When this capacitor degrades or fails, you'll typically notice symptoms such as the motor humming without spinning, the system short-cycling due to thermal overload, sluggish motor startup, or a complete motor no-start condition — all of which can rapidly escalate to full motor burnout if left unaddressed.

  • Specs: Single run capacitor | Factory OEM-matched MFD rating | 370V/440V rated | Cylindrical case | Tight ±3% capacitance tolerance for optimal motor performance
  • OEM vs Generic: This is a genuine OEM Carrier part (P291-1003), manufactured to exact factory specifications. Generic aftermarket capacitors typically carry a loose ±10% MFD tolerance, which accelerates motor winding stress, increases heat buildup, and significantly shortens motor life — costing far more in the long run.
  • Install Difficulty: 2/5 — A straightforward single-capacitor swap suitable for experienced DIYers and technicians. 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. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier PG8MAA048110ABJA packaged unit. Always verify the MFD rating and voltage stamped on your existing capacitor's label against your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — contact us anytime.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor P291-1003 — PG8MAA048110ABJA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor P291-1003 — PG8MAA048110ABJA. 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 OEM Carrier Single Run Capacitor P291-1003 — PG8MAA048110ABJA?
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?
