What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model 09DE054C900 is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number 09DE054C900.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Single Run Capacitor 7.5 / 10 MFD 440V for Model 09DE054C900

This is the factory-specified OEM single run capacitor for the Carrier 09DE054C900, available in two MFD ratings to match your unit's data plate: P291-0754 (7.5 MFD) and P291-1004 (10 MFD). The run capacitor provides the continuous electrical charge required to keep the blower motor spinning efficiently throughout every heating and cooling cycle. When this component fails, symptoms include a humming motor that won't turn, the blower motor running hot and tripping thermal overload, or the motor failing to start entirely — leaving your system unable to circulate conditioned air.

Specs: P291-0754 — 7.5 MFD ±6% | 440V | Oval case | 50/60 Hz | UL Listed & RoHS Compliant. P291-1004 — 10 MFD ±5% | 440V | Oval case | 50/60 Hz | UL Listed & RoHS Compliant.
OEM vs Generic: These are genuine Carrier Totaline-brand capacitors engineered to ±5–6% MFD tolerance. Generic capacitors frequently run ±10% or wider, which accelerates motor winding wear and can shorten blower motor life significantly. Always match the MFD value on your unit's wiring diagram label exactly.
Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: flathead screwdriver, needle-nose pliers, and a multimeter for pre-install verification. Critical safety step: discharge the capacitor terminals to ground with an insulated screwdriver before touching any leads. Photograph all wire connections before removal.
Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse. Oval form factor fits standard blower compartment mounting brackets on the Carrier 09DE054C900.

Compatibility & Ordering Note: Fits Carrier model 09DE054C900. Verify the MFD rating printed on your existing capacitor or the unit's wiring schematic before selecting between P291-0754 (7.5 MFD) and P291-1004 (10 MFD). P291-0754 directly replaces P291-0753 and HC91CA007. P291-1004 directly replaces P291-1003 and a wide range of cross-references including HC90BB010 and HC91DA010.

Frequently Asked Questions

Does this Capacitor fit my Carrier 09DE054C900?

Yes. This is the factory-specified OEM capacitor for the Carrier 09DE054C900. 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 09DE054C900?

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?
