OEM Carrier Dual Round Run Capacitor 45/5 MFD for PH13NR036000AAAA

The run capacitor stores and releases electrical energy to keep the compressor and condenser fan motor running efficiently on the PH13NR036000AAAA. A dual round capacitor serves both loads from one can — the HERM terminal feeds the compressor, the FAN terminal feeds the fan motor. When it weakens or fails you'll notice the fan struggling to start (a hum followed by nothing until you spin the blade by hand), the compressor clicking on its overload, warm air, short-cycling, and a bulged or leaking capacitor top. A failed capacitor is the single most common no-cool service call. This is a dual run capacitor, commonly 45/5 MFD at 440V (45 MFD HERM / 5 MFD FAN), with an OEM tolerance of ±5%. That tight tolerance matters: a capacitor reading more than 6% below its rating should be replaced. Verify both MFD values and the voltage rating (a 440V can is backward-compatible with 370V loads, not the reverse) against the label on your old capacitor. OEM capacitors hold ±5% tolerance and are rated for full HVAC duty cycle and ambient heat. Generic capacitors often drift to ±10–15%, which throws the motor's phase angle off — the compressor windings draw higher amperage, run hotter, and lose years of service life. An out-of-spec capacitor is cheap to buy and expensive to ignore, so match the exact MFD and voltage. Install difficulty: 2/5. Tools: 1/4" nut driver, a multimeter with capacitance (MFD) mode, an insulated screwdriver, and a phone photo of the terminal wiring. #1 safety warning: ALWAYS discharge the capacitor across an insulated 20k-ohm resistor before touching the terminals — a charged run capacitor holds a dangerous shock long after the breaker is off. Ships same business day from our stocked warehouse on orders placed before 3 PM CST, backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PH13NR036000AAAA. 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.
