OEM Carrier Single Run Capacitor 15 MFD 370V for Model PG8MAA048070ADJA

This OEM single run capacitor is the factory-specified replacement part for the Carrier PG8MAA048070ADJA gas furnace. The run capacitor maintains the continuous phase-shifted current that keeps the blower motor spinning at proper speed after start-up. When this component fails, you'll typically experience symptoms such as a humming blower motor that won't spin, intermittent motor starting, or the furnace shutting down on limit due to restricted airflow caused by a failed blower. Replacing a degraded capacitor promptly protects the blower motor from overheating and premature failure.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals | ±5% MFD tolerance
  • OEM vs Generic: This OEM Carrier/Totaline capacitor is built to exact factory specifications. Generic alternatives often carry a wider ±10% MFD tolerance, which can reduce motor efficiency, increase heat buildup, and shorten blower motor life over time.
  • Install difficulty: 2/5 — Always disconnect power and discharge the capacitor before handling. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (for pre/post verification). Photograph all wiring connections before removal. Note: P291-1503 has been superseded by P291-1504 (440V); verify your unit's data plate voltage rating before ordering.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as the OEM replacement for Carrier model PG8MAA048070ADJA gas furnaces. Carrier sources capacitors from select manufacturers; labeling on the component will reflect the capacitor manufacturer's name. Verify the MFD and voltage rating on your unit's data plate before ordering. Our team is available to confirm fitment — reach out before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA048070ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA048070ADJA. 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 PG8MAA048070ADJA?
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.
