OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNA070000AAAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PF1MNA070000AAAA fan coil and air handler unit. The run capacitor stores and releases the precise electrical charge needed to keep the blower motor running smoothly and efficiently. When this capacitor degrades or fails, you'll notice symptoms such as the motor humming but failing to start, intermittent short-cycling, sluggish blower performance, or a complete failure to run — leaving you without conditioned air when you need it most.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | UL approved current interrupter | Non-PCB dielectric fluid | Factory-matched ±5% tolerance
  • OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor (P291-1503), manufactured to exact factory tolerances. Generic aftermarket capacitors often deviate ±10% MFD, which accelerates motor winding stress and significantly shortens motor life over repeated start cycles.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate prior to installation.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PF1MNA070000AAAA fan coil/air handler. Note: OEM part P291-1503 has been superseded by P291-1504 in some production runs — our team verifies current fitment before every order ships. Questions about compatibility? Contact us and we'll confirm the right part for your unit before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PF1MNA070000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PF1MNA070000AAAA. 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 PF1MNA070000AAAA?
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.
