OEM Carrier Dual Run Capacitor for PH12NA02400GADAA Heat Pump

The dual run capacitor is the small cylinder that gives both your compressor and condenser fan motor the electrical push they need to start and run smoothly in your Carrier PH12NA02400GADAA heat pump. It stores and releases energy on every cycle. When it weakens — and capacitors are the single most common HVAC failure — you'll hear a hum from the outdoor unit that won't start, see the fan needing a stick-push to spin, notice warm air, frequent breaker trips, or a compressor that buzzes and clicks off on overload. A bulging or leaking top is a dead giveaway. This genuine Carrier dual capacitor carries the exact factory MFD ratings (a HERM side for the compressor and a FAN side for the motor) at 440VAC, held to a tight OEM tolerance of ±5%. That precision keeps both motors running at their designed phase angle and amp draw. OEM tolerance is the whole story with capacitors. Cheap aftermarket units are often rated to only ±10–15%, so a 'matching' part can actually run 15% low out of the box and drift further with heat. An under-spec capacitor forces the compressor windings to pull extra amperage, runs them hotter, and quietly shaves years off a compressor worth thousands. Correct MFD is cheap insurance. Install difficulty: 2 of 5 — one of the easiest repairs. Tools: a 1/4 in. nut driver, needle-nose pliers, and a multimeter with a capacitance setting to confirm the reading. Photograph the terminals (C / HERM / FAN) before removing leads. The #1 safety rule: a capacitor holds a dangerous charge even with power off — always discharge it across an insulated resistor before touching the terminals.

Compatibility

This part is compatible with Carrier model PH12NA02400GADAA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
