OEM Carrier Start Capacitor P281-8806 for Model PH4RNG018000BAAA

This is the factory-specified OEM start capacitor for the Carrier PH4RNG018000BAAA heat pump system. The start capacitor delivers a high-energy burst of stored electrical charge to kick the compressor into motion at startup. Without a properly functioning start capacitor, the compressor may hum loudly, fail to start, draw excessive amperage, or trip the circuit breaker — all signs that this component needs immediate replacement.

• Specs: OEM Part Number P281-8806 | Factory-matched microfarad (MFD) and voltage ratings | Engineered to exact Carrier specifications for the PH4RNG018000BAAA platform
• OEM vs Generic: This OEM unit is built to Carrier's factory tolerance standards. Aftermarket start capacitors frequently ship with looser MFD tolerances, placing added strain on the compressor motor windings and shortening overall system life.
• Install Difficulty: 3/5 — Always shut off power at the disconnect and breaker before beginning work. Discharge the capacitor fully using an insulated resistor before handling. Tools needed: insulated screwdrivers, needle-nose pliers, multimeter, and a capacitor discharge tool. Photograph all wiring connections before disconnecting.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our climate-controlled warehouse.
