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.
