OEM Carrier Dual Run & Start Capacitor Kit for Model PH12NA03000GACAA

This OEM capacitor kit includes both the P291-4573RS Dual Run Capacitor and the P281-8806 Start Capacitor — the factory-specified replacements for the Carrier PH12NA03000GACAA heat pump condenser. The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. The start capacitor provides an additional torque boost during compressor startup. When either component fails, you may experience symptoms such as a loud hum with no motor movement, the system short-cycling within the first few minutes of operation, tripped breakers, or a complete failure to start.

  • Included Parts: P291-4573RS Dual Run Capacitor | P281-8806 Start Capacitor — both factory-matched to Carrier PH12NA03000GACAA specifications for guaranteed fitment and performance
  • OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerance (±3%), ensuring consistent motor performance and maximum compressor lifespan. Generic alternatives often run ±10% tolerance, which accelerates motor and compressor wear over time.
  • Install Difficulty: 2/5 — Always disconnect power and fully discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, insulated discharge resistor, and a multimeter to verify discharge. Photograph all wiring connections before removal.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. Orders ship the same business day from our warehouse — get your system back up and running fast.

Compatibility: Engineered specifically for the Carrier PH12NA03000GACAA heat pump. Always verify the MFD rating, voltage rating, and terminal configuration against your unit's data plate before installing. Our technical team is available to confirm fitment before you order — don't guess on capacitors.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH12NA03000GACAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH12NA03000GACAA. 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 PH12NA03000GACAA?
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.
