OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH14NA018000AAAA

This is the factory-authorized OEM start capacitor (part number P281-8806) for the Carrier PH14NA018000AAAA heat pump. The start capacitor provides the short-duration electrical boost the compressor needs to overcome inertia and reach operating speed on each cooling or heating cycle. When this capacitor fails, the compressor struggles to start, draws excessive locked-rotor amperage, and will typically trip on thermal overload — leaving you with a system that hums briefly and then shuts off, or one that won't start at all. Replacing a failed start capacitor promptly also protects your compressor from repeated hard-start stress and premature wear.

  • Specs: 88–108 MFD (microfarad) | 330V rated | 2.06" diameter × 4.37" length | Round case with bleed resistor | Factory-matched tolerance
  • OEM vs Generic: This is a genuine Carrier-sourced capacitor meeting exact factory MFD tolerance. Off-brand capacitors often carry a wide ±10% tolerance that can stress your compressor motor windings and shorten system life.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PH14NA018000AAAA heat pump condensing units. Always verify the MFD range and voltage rating on your unit's data plate or existing capacitor before ordering. Our parts specialists are available to confirm fitment — order with confidence and get back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Start Capacitor 88-108 MFD 330V — PH14NA018000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Start Capacitor 88-108 MFD 330V — PH14NA018000AAAA. 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 OEM Carrier Start Capacitor 88-108 MFD 330V — PH14NA018000AAAA?
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?
