OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH4RNG048000BBAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH4RNG048000BBAA packaged heat pump unit. The start capacitor delivers the high-voltage jolt of energy needed to energize the compressor motor at startup. Without a functioning start capacitor, the compressor will attempt to start, draw excessive amperage, and either trip the breaker or cycle off on thermal overload — leaving you with a unit that hums but won't cool or heat. A failed start capacitor will often appear swollen, leaking, or will read out-of-range on a capacitor tester.

• Specs: 88–108 MFD (microfarad) | 330V rated | Includes bleed resistor | Oval/round case | Factory-matched tolerance per Carrier specification P281-8806
• OEM vs Generic: This is a genuine OEM-sourced Carrier/Totaline capacitor matched to the exact MFD range and voltage your unit demands. Generic alternatives often carry loose ±10% tolerances that can stress the compressor motor windings over time and void equipment warranties.
• Install difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH4RNG048000BBAA packaged heat pump. Cross-references include BMI, 1017H, 092A088B330CE7X, 88-108UF, 1403H, and Totaline factory-authorized parts. Always verify the MFD rating and voltage printed on your existing capacitor's data label before ordering to ensure an exact match. Have a fitment question?
