OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNA048000AAAA

This is the factory-specified OEM single run capacitor (P291-1503) for the Carrier PF1MNA048000AAAA fan coil and associated HVAC equipment. The run capacitor maintains the continuous phase-shifted current needed to keep the motor running at rated torque and efficiency. When this capacitor weakens or fails, you'll notice symptoms such as a humming condenser with no motor start, intermittent short-cycling, reduced airflow, compressor overheating, or a tripped high-pressure limit. Replacing it promptly prevents costly secondary damage to the motor windings or compressor.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | ±5% factory tolerance | Multiple electrical terminals
  • OEM vs Generic: This is the genuine Carrier/Totaline OEM part, sourced through authorized distribution channels. Generic capacitors commonly run ±10% MFD tolerance, which accelerates motor wear and may void compressor warranties. The OEM unit is factory-matched for exact fit and electrical spec.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling — stored charge can cause serious injury. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Typical replacement time: 15–20 minutes.
  • Warranty: 1-year OEM manufacturer warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Factory replacement for Carrier model PF1MNA048000AAAA. OEM part number P291-1503; superseded by P291-1504 where noted. Verify the MFD and voltage ratings on your unit's data plate before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you buy — no guesswork required. In stock — order now and ship today.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 15 MFD 370V — PF1MNA048000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 15 MFD 370V — PF1MNA048000AAAA. 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 15 MFD 370V — PF1MNA048000AAAA?
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?
