OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA048135ADJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier PG8MAA048135ADJA gas furnace. The run capacitor sustains the electrical charge that keeps the indoor blower motor spinning at rated speed. When this component weakens or fails, the blower motor struggles to reach full RPM — symptoms include an audible hum with no airflow, a motor that stalls shortly after startup, or a furnace that trips on high-limit due to insufficient airflow across the heat exchanger.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | ±5% tolerance | 50/60 Hz | Operating temp: -40°C to +70°C | Non-PCB design
  • OEM vs Generic: This OEM Carrier capacitor is manufactured to exact factory tolerances, ensuring the blower motor receives the precise electrical support it was designed for. Generic aftermarket capacitors often carry wider MFD tolerances (±10%), which can cause premature motor wear and reduce blower motor lifespan.
  • Install difficulty: 1/5 — One of the simplest HVAC repairs available. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, and a multimeter to confirm the old capacitor has discharged before handling. Always photograph the existing wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3PM ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA048135ADJA gas furnace. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor before ordering to ensure a correct fit.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 10 MFD 370V — PG8MAA048135ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 10 MFD 370V — PG8MAA048135ADJA. 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 10 MFD 370V — PG8MAA048135ADJA?
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?
