OEM Carrier Dual Run & Start Capacitor Kit (P291-3553RS + P281-8806) for Model PH13NR018000ACAA

This factory-matched OEM capacitor kit includes both the dual run capacitor (P291-3553RS) and the start capacitor (P281-8806) specified for the Carrier PH13NR018000ACAA split-system heat pump. The dual run capacitor continuously supports both the compressor and condenser fan motor during operation, while the start capacitor provides a powerful extra torque boost to reliably kick the compressor into motion on every cycle. When either capacitor fails, symptoms range from a humming unit that won't start, to a compressor that trips the breaker, short-cycles within minutes, or fails to cool or heat entirely — leaving you with a fully non-functional system.

  • Dual Run Capacitor Specs (P291-3553RS): 35+5 MFD (microfarad) | 370V rated | Round style | Terminals: HERM–C–FAN | Factory ±3% tolerance | Manufactured by GE/Genteq for Carrier
  • Start Capacitor Specs (P281-8806): 88–108 MFD | 330V rated | With bleed resistor | 2.06" diameter | Cycles on the compressor at startup to prevent hard-start burnout
  • OEM vs Generic: These are genuine Carrier-sourced OEM capacitors built to exact factory tolerances. Generic aftermarket alternatives commonly run ±10% MFD drift, which accelerates compressor wear, increases amp draw, and can void equipment warranties. Replacing both capacitors together as a kit is best practice and maximizes system longevity.
  • Install Difficulty: 2/5 — Always discharge capacitors before handling — they store lethal voltage even with power off. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Start cap typically mounts near the contactor; run cap mounts in the outdoor unit's control section.
  • Warranty: 1-year OEM factory warranty on both capacitors. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: This kit is engineered for the Carrier PH13NR018000ACAA heat pump condenser. Always verify the MFD and voltage ratings on your unit's data plate before ordering — using a capacitor with incorrect MFD will damage the compressor. Cross-references include HC98JA036D, HC98CA036, HC95DD088, and HC95DE088. Need fitment confirmed before you order? Our HVAC parts specialists verify compatibility at no charge — contact us today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH13NR018000ACAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH13NR018000ACAA. 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 PH13NR018000ACAA?
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.
