OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH13NR01800GAAAA

This is the genuine OEM Carrier start capacitor (part number P281-8806), the factory-specified replacement for the Carrier PH13NR01800GAAAA heat pump. The start capacitor delivers a powerful burst of electrical energy to the compressor motor at the moment of startup, giving it the torque needed to overcome static refrigerant pressure and begin its cycle. Without a functioning start capacitor, the compressor either fails to start entirely, hums and trips the breaker, or draws excessive amperage that shortens its lifespan. If your Carrier PH13NR01800GAAAA won't cool, trips repeatedly, or you hear a single hum followed by shutdown, a failed start capacitor is one of the most common and cost-effective culprits to check first.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" height | Includes bleed resistor for safe passive discharge
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM capacitors are manufactured to exact MFD tolerance for the PH13NR01800GAAAA compressor. Generic capacitors often ship with ±10% MFD drift, which stresses the compressor windings and voids manufacturer warranties.
• Install difficulty: 2/5 — Always shut off power at the disconnect before servicing. Even with power off, capacitors can hold a dangerous charge — use an insulated discharge tool or resistor before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old capacitor.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed and specified for the Carrier PH13NR01800GAAAA heat pump. Also cross-references part numbers HC95DD088, HC95DE088, 38GK52747D1, 301023-101, and 300749-101. 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 — reach out before placing your order.
