OEM Carrier Dual Run Capacitor P291-5554RS for Model HB1AJX060000AAAA

This is the genuine OEM dual run capacitor (part number P291-5554RS) factory-specified for the Carrier HB1AJX060000AAAA packaged unit. The dual run capacitor serves a critical role in your system — it stores and delivers the electrical charge required to start and continuously run both the compressor and the condenser fan motor from a single unit. Common failure symptoms include a humming noise with no compressor or fan start, intermittent short-cycling, tripped breakers, or a system that blows warm air despite powering on. A failed capacitor is one of the most frequent causes of no-cooling calls and is one of the most cost-effective repairs available.

  • Specs: OEM part number P291-5554RS | Dual run configuration (compressor + fan) | Factory-matched MFD and voltage rating | Round case design for direct drop-in fitment on Carrier HB1AJX060000AAAA
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory tolerance (±3% MFD). Aftermarket generic capacitors often carry a ±10% tolerance, which can cause premature compressor and fan motor wear, voiding equipment warranties and shortening component life.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling — stored voltage can cause serious injury even after power is disconnected. Tools needed: 1/4" nut driver, needle-nose pliers, insulated discharge resistor or screwdriver, and a multimeter to confirm discharge. Photograph all wiring connections before removal.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse — get your system back online fast.

Compatibility: Designed and tested for the Carrier HB1AJX060000AAAA packaged unit. Always verify the MFD and voltage ratings printed on your existing capacitor's label or your unit's data plate before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility before you buy — don't guess on a critical electrical component.

Frequently Asked Questions

Does this Capacitor fit my Carrier HB1AJX060000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier HB1AJX060000AAAA. 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 HB1AJX060000AAAA?
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.
