OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA048135AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA048135AAJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running efficiently after start-up. When it degrades or fails, you'll notice symptoms such as the blower motor humming without spinning, the furnace cycling off on high-limit due to airflow loss, or the motor running sluggishly and overheating — all of which can cascade into costly motor replacement if left unaddressed.

  • Specs: Single run capacitor | Factory OEM-matched MFD rating | 370V/440V rated | Designed to Carrier factory tolerances (±3% MFD) for the PG8MAA048135AAJA platform
  • OEM vs Generic: This is a genuine OEM Carrier part — not an aftermarket substitute. Generic capacitors frequently ship at ±10% MFD tolerance, which accelerates motor winding wear and can void blower motor warranties. OEM ensures exact electrical characteristics every time.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before disconnecting. Power must be OFF at the breaker and the unit disconnect.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PG8MAA048135AAJA gas furnace. Always cross-reference the MFD and voltage rating printed on your existing capacitor's label or the unit's wiring diagram before installing. Our parts specialists are available to confirm fitment — reach out before ordering if you have any questions. Order today and get same-day shipping!

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA048135AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA048135AAJA. 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 PG8MAA048135AAJA?
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.
