OEM Carrier 45/5 MFD Dual Run Capacitor for PH10JA04200GABAA

The dual run capacitor provides the constant phase shift that keeps both the compressor and the condenser fan motor running smoothly in your Carrier PH10JA packaged unit. It is one of the most common failure points in any HVAC system. When it weakens or fails, the symptoms are immediate: the outdoor unit hums but won't start, the fan turns slowly or not at all, the compressor clicks on its overload and shuts down, or the system trips the breaker on startup. A bulging or domed top, or leaking oil, is a sure sign the capacitor is finished. This is a dual-rated 45/5 MFD capacitor — 45 µF for the compressor (HERM terminal) and 5 µF for the fan (FAN terminal) — rated at 440VAC, matched to Carrier's original specification. OEM capacitors hold a tight ±5% tolerance, oval/round form factor, with three terminal posts (HERM, FAN, C). For a capacitor, OEM tolerance is everything. A generic cap with ±10–15% tolerance — common in aftermarket parts — delivers the wrong microfarad value, which stresses the compressor start and run windings, causes them to overheat, and dramatically shortens compressor life. The right MFD keeps your most expensive component cool and balanced. Installation difficulty: 2/5. Tools needed: 1/4" nut driver, an insulated screwdriver, needle-nose pliers, and a multimeter with capacitance mode. #1 safety warning: a capacitor STORES a lethal charge — discharge it across the terminals with an insulated resistor before touching the leads, even after the breaker is off.

Compatibility

This part is compatible with Carrier model PH10JA04200GABAA. 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.
