OEM Carrier Dual Run & Start Capacitor Kit for Model PH12NA03000GACAA

This OEM capacitor kit includes both the P291-4573RS Dual Run Capacitor and the P281-8806 Start Capacitor — the factory-specified replacements for the Carrier PH12NA03000GACAA heat pump condenser. The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. The start capacitor provides an additional torque boost during compressor startup. When either component fails, you may experience symptoms such as a loud hum with no motor movement, the system short-cycling within the first few minutes of operation, tripped breakers, or a complete failure to start.

• Included Parts: P291-4573RS Dual Run Capacitor | P281-8806 Start Capacitor — both factory-matched to Carrier PH12NA03000GACAA specifications for guaranteed fitment and performance
• OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerance (±3%), ensuring consistent motor performance and maximum compressor lifespan. Generic alternatives often run ±10% tolerance, which accelerates motor and compressor wear over time.
• Install Difficulty: 2/5 — Always disconnect power and fully discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, insulated discharge resistor, and a multimeter to verify discharge. Photograph all wiring connections before removal.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. Orders ship the same business day from our warehouse — get your system back up and running fast.

Compatibility: Engineered specifically for the Carrier PH12NA03000GACAA heat pump. Always verify the MFD rating, voltage rating, and terminal configuration against your unit's data plate before installing. Our technical team is available to confirm fitment before you order — don't guess on capacitors.
