OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH12NA01800GADAA

This factory OEM capacitor kit includes both the dual run capacitor (P291-3553RS) and the start capacitor (P281-8806) — the two capacitors your Carrier PH12NA01800GADAA unit depends on for reliable compressor and condenser fan motor operation. The dual run capacitor stores and delivers the sustained electrical charge to keep the compressor and fan motor running, while the start capacitor provides the extra torque burst needed to get the compressor spinning on each cooling cycle. When either fails, symptoms range from a loud hum with no motor start, to hard short-cycling, to complete system lockout on a hot day when you need it most.

• Includes: P291-3553RS Dual Run Capacitor + P281-8806 Start Capacitor | Factory-matched MFD and voltage ratings | Round case design | OEM ±3% tolerance — verify exact MFD/voltage on your unit's data plate before ordering
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact electrical tolerance specifications. Generic aftermarket capacitors frequently ship at ±10% MFD deviation, which places added thermal stress on the compressor windings and shortens system life — a risk not worth taking on a premium unit like the PH12NA01800GADAA.
• Install Difficulty: 2/5 — Always discharge capacitors fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. If unfamiliar with live 240V work, consult a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: This kit is the factory-specified capacitor replacement for the Carrier PH12NA01800GADAA. Always cross-reference the MFD rating, voltage rating, and terminal configuration printed on your existing capacitor's label before finalizing your order.
