OEM Carrier Single Run Capacitor 7.5–30 MFD 440V for Model 09DE084C510

This OEM single run capacitor is the factory-specified replacement for the Carrier 09DE084C510 air conditioning system. Single run capacitors remain energized throughout motor operation, stabilizing voltage and sustaining the torque needed to keep the compressor or condenser fan motor running efficiently. When a run capacitor fails, the most common symptoms are a loud hum with no motor movement, the unit short-cycling within seconds of startup, or a complete failure to cool. Replacing it promptly prevents downstream damage to the compressor and fan motor windings.

  • Specs: Available in 7.5 MFD (P291-0754), 25 MFD (P291-2504), and 30 MFD (P291-3004) | All rated 440V | Oval case style | Factory-matched ±5% MFD tolerance | Replaces OEM cross-references 97F9036 and 43-25136-05 (P291-0754)
  • OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances for the 09DE084C510. Generic capacitors often deviate ±10% MFD, placing unnecessary stress on motor windings and shortening compressor life — especially during peak summer demand.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect and allow 5+ minutes for the capacitor to self-discharge before handling terminals. Tools needed: 1/4″ nut driver, needle-nose pliers, multimeter (to verify discharge and confirm capacitance). Photograph all wiring before disconnecting. Match MFD rating exactly — do not substitute a different MFD value.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model 09DE084C510. Verify the MFD rating printed on your existing capacitor's label or your unit's wiring diagram before selecting between P291-0754 (7.5 MFD), P291-2504 (25 MFD), and P291-3004 (30 MFD). Voltage must be 440V. Questions about fitment? Our HVAC parts specialists confirm compatibility before you order — call or chat today.

Frequently Asked Questions

Does this Capacitor fit my Carrier 09DE084C510?
Yes. This is the factory-specified OEM capacitor for the Carrier 09DE084C510. 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 09DE084C510?
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.
