OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA048110ADJA

This OEM single run capacitor (Carrier part number P291-1003) is the factory-specified replacement for the Carrier PG8JAA048110ADJA gas furnace. The run capacitor sustains the continuous phase-shifted current that keeps the blower motor spinning at proper speed and efficiency. When it degrades or fails, you'll typically notice a humming blower that won't start, sluggish motor spin-up, repeated tripping of the thermal overload, or a furnace that shuts down shortly after ignition due to airflow proving issues. Replacing a worn capacitor promptly protects the blower motor from overheating and premature failure.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±6% factory tolerance | 50/60 Hz | Non-PCB dielectric fluid | UL-recognized current interrupter | Operating range: -40°C to +70°C
  • OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerances. Generic capacitors frequently run outside ±10% MFD tolerance, causing the blower motor to run hot, draw excess current, and fail prematurely — negating any cost savings.
  • Install difficulty: 2/5 — Disconnect power and discharge the capacitor before touching terminals. Tools needed: 1/4" nut driver or flat-blade screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph the original wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Direct OEM replacement for Carrier model PG8JAA048110ADJA gas furnaces. Note: P291-1003 has been superseded by P291-1004 — both part numbers are cross-compatible and represent the same 10 MFD 370V specification. Verify the MFD rating and voltage on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — contact us anytime.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA048110ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA048110ADJA. 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 PG8JAA048110ADJA?
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.
