OEM Carrier Dual Run & Start Capacitor Kit — P291-3553RS + P281-8806 for Model PH4RNG024000BAAA

This factory-matched OEM capacitor kit contains both the dual run capacitor (P291-3553RS) and the start capacitor (P281-8806) specified for the Carrier PH4RNG024000BAAA packaged heat pump unit. The dual run capacitor simultaneously energizes the compressor (HERM terminal) and the condenser fan motor (FAN terminal), while the start capacitor delivers the extra torque burst the compressor needs on each startup cycle. When either capacitor degrades, symptoms include a hard-starting compressor, a humming condenser fan that won't spin up, or a unit that trips on high-pressure lockout within the first minute of operation.

  • Dual Run Capacitor Specs (P291-3553RS): 35 + 5 MFD | 370 VAC | Round case | Terminals: HERM / C / FAN | OEM manufacturer: GE/Genteq
  • Start Capacitor Specs (P281-8806): 88–108 MFD | 330 VAC | Integrated bleed resistor | OEM-sourced by Carrier/Totaline
  • OEM vs Generic: OEM capacitors are built to exact factory MFD tolerances (±5%), protecting compressor windings and fan motor bearings. Generic units often run ±10–15% MFD, accelerating wear and shortening equipment life — especially critical on hard-starting packaged units.
  • Install difficulty: 2/5 — Always discharge the run capacitor before touching terminals. Tools needed: 1/4" and 5/16" nut drivers, insulated needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The start capacitor mounts in a dedicated bracket near the compressor contactor.
  • Warranty: 1-year OEM factory warranty on both capacitors. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH4RNG024000BAAA packaged heat pump. Verify capacitor ratings on your unit's data plate before installation — MFD and voltage must match exactly. The run capacitor voltage may be upgraded to 440V if a direct 370V replacement is unavailable, but MFD values must remain identical. Have questions about fitment? Our HVAC parts specialists verify compatibility before you order — reach out before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH4RNG024000BAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH4RNG024000BAAA. 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 PH4RNG024000BAAA?
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.
