OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH4RNG048000BAAA

This is the genuine OEM start capacitor (part number P281-8806) factory-specified for the Carrier PH4RNG048000BAAA packaged heat pump unit. The start capacitor provides the high-voltage surge of stored energy needed to spin the compressor motor from rest to operating speed. Without a functioning start capacitor, the compressor will struggle to start, draw excessive current, trip thermal overloads, or fail to start entirely — leaving you with no heating or cooling. A swollen case, burned smell, or a unit that hums briefly then shuts off are the classic signs this part has failed.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" height | Includes bleed resistor for safe discharge
• OEM vs Generic: This is a genuine Carrier OEM part — factory-matched to exact MFD tolerance. Generic start capacitors often ship at ±10% MFD variance, which stresses the compressor motor windings and shortens service life significantly.
• Install difficulty: 3/5 — Always de-energize the unit and verify the capacitor is fully discharged through its bleed resistor before handling. Tools needed: insulated screwdriver, ¼" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting terminals.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
