What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model 09DE084910 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 09DE084910.

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 MFD 440V for Model 09DE084910

This OEM single run capacitor (part number P291-0754) is the factory-specified replacement for the Carrier 09DE084910 unit. The run capacitor delivers and sustains the precise electrical charge needed to start and keep the condenser fan motor running throughout every cooling cycle. A failing capacitor is one of the most common HVAC service calls — symptoms include a humming condenser fan that won't spin up, a motor that overheats and trips on thermal protection, or a unit that short-cycles and shuts down within minutes of startup.

Specs: 7.5 MFD (microfarad) ±6% tolerance | 370/440V dual-rated | 50/60 Hz | Oval CBB65A case | Factory-matched Totaline by Carrier specification
OEM vs Generic: This OEM capacitor meets Carrier's exact ±6% MFD tolerance, ensuring proper motor torque and thermal protection. Generic capacitors often run ±10% or wider, accelerating fan motor wear and risking premature compressor damage.
Install difficulty: 1/5 — One of the simplest HVAC repairs. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (to verify discharge). Always discharge the old capacitor fully before touching terminals, and photograph wire positions before disconnecting.
Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model 09DE084910. Verify your existing capacitor's MFD rating and voltage on the unit data plate or the old capacitor label before ordering. This oval-style capacitor replaces 97F9036 and fits both 370V and 440V applications. Our fitment team is available to confirm compatibility before you order — no guesswork required.

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.
