OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH4RNG030000BAAA

This OEM start capacitor (Part# P281-8806) is the factory-specified replacement for the Carrier PH4RNG030000BAAA packaged heat pump unit. The start capacitor delivers the high-voltage electrical boost required to bring the compressor motor up to running speed. Without a properly functioning start capacitor, the compressor will hum and fail to turn on — often triggering a high-pressure lockout or tripping the breaker. If your unit is making a clicking or buzzing noise but the compressor never fully starts, a failed start capacitor is one of the most common culprits.

  • Specs: 88–108 MFD (microfarad) | 330V rated | Round case, 2.06" diameter | Includes integrated bleed resistor for safe discharge | Factory ±tolerance matched
  • OEM vs Generic: This is a genuine OEM Carrier part sourced through the Totaline® factory parts program. OEM capacitors maintain exact MFD tolerance critical for compressor longevity. Generic alternatives can run wide tolerance swings, placing excess strain on the compressor windings over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use a resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify MFD before and after). Photograph all wiring connections before disconnecting.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our climate-controlled warehouse. Free shipping on orders over $99.

Compatibility: Designed for the Carrier PH4RNG030000BAAA packaged heat pump. Cross-references include part numbers 1017H, 092A088B330CE7X, 88-108UF, and 1403H. Always verify MFD rating and voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH4RNG030000BAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH4RNG030000BAAA. 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 PH4RNG030000BAAA?
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.
