OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH13NR048000AHAA

This is the OEM factory-specified start capacitor for the Carrier PH13NR048000AHAA heat pump condenser. The start capacitor delivers the short but powerful surge of electrical energy needed to kick the compressor motor into motion on every cooling or heating cycle. Without a healthy start capacitor, the compressor struggles to turn over — you'll typically hear a loud hum or clicking sound followed by a tripped breaker, a hard-start delay, or a complete no-start condition. Replacing a failed start capacitor promptly protects the compressor from heat and winding damage caused by prolonged locked-rotor current draw.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" length | Includes bleed resistor | 50/60 Hz
• OEM vs Generic: OEM Carrier capacitors (P281-8806) are manufactured to exact factory MFD tolerance, ensuring reliable cold starts and full compressor protection. Generic start capacitors often carry wider tolerance bands that can under-boost the compressor motor, shortening its service life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit. Swap terminals one at a time to avoid miswiring.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM drop-in for the Carrier PH13NR048000AHAA 4-ton heat pump condenser. Always verify the MFD range and voltage rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
