OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH13NR048000ACAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH13NR048000ACAA heat pump condenser. The start capacitor delivers the high-voltage electrical boost the compressor needs to overcome inertia and begin its rotation. When this component fails, the compressor draws locked-rotor amperage, trips the breaker, or simply refuses to start — leaving your system in a no-cooling or no-heating condition. A failing start capacitor may also cause audible clicking or humming from the outdoor unit with no compressor operation.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" length | Includes bleed resistor for safe discharge | Cross-references: 1017H, 092A088B330CE7X, 1403H
• OEM vs Generic: This is a genuine OEM-spec Carrier part (P281-8806). OEM start capacitors are manufactured to exact MFD tolerances, ensuring full compressor torque on every start. Generic alternatives often run outside rated MFD, stressing the compressor motor windings and shortening equipment life.
• Install difficulty: 2/5 — Always disconnect power and discharge the capacitor before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter. The built-in bleed resistor helps safely dissipate stored charge, but always verify with a meter before touching terminals. Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NR048000ACAA 4-ton heat pump condenser. Verify the MFD range and voltage rating on your unit's data plate before ordering to ensure correct fitment. Need help confirming compatibility? Our HVAC parts specialists verify fitment before you buy — just ask.
