OEM Carrier Dual Run Capacitor & Start Capacitor for Model HC1CJX048000AAAA

These factory-matched OEM capacitors — P291-4074RS (Dual Run) and P281-8806 (Start) — are the manufacturer-specified replacements for the Carrier HC1CJX048000AAAA 4-ton condensing unit. The dual run capacitor continuously powers both the compressor and condenser fan motor, while the start capacitor provides the high-torque burst of energy needed to get the compressor spinning under load. When either fails, symptoms include a loud hum with no motor movement, repeated tripped breakers, compressor short-cycling, or a fan that spins freely by hand but won't self-start under power.

  • Specs: P291-4074RS Dual Run Capacitor — matches factory MFD and 370V/440V rating for HC1CJX048000AAAA | P281-8806 Start Capacitor — factory-rated MFD boost range and voltage | Round-case design | ±3% OEM tolerance on both units
  • OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances, protecting your compressor and fan motor from voltage spikes and premature wear. Generic aftermarket units commonly ship at ±10% MFD tolerance, which shortens compressor life and can void equipment warranties.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect and discharge the capacitor terminals with an insulated resistor before handling. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. The start capacitor installs in series with the start winding; the dual run mounts in the unit's control compartment.
  • Warranty & Shipping: Both capacitors carry a 1-year OEM factory warranty against defects. Orders ship same business day from our dedicated HVAC parts warehouse — get your system cooling again fast.

Compatibility: Designed specifically for the Carrier HC1CJX048000AAAA 4-ton condensing unit. Always verify the MFD rating and voltage printed on your existing capacitor's label against your unit's data plate before ordering — MFD values vary by production run. Not sure? Our fitment team confirms compatibility before you buy. Order now and ship today.

Frequently Asked Questions

Does this Capacitor fit my Carrier HC1CJX048000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier HC1CJX048000AAAA. 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 HC1CJX048000AAAA?
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.
