OEM Carrier Dual Run Capacitor 45/5 MFD for PH13NR036000AEAA

The dual run capacitor gives both the compressor and the condenser fan motor in your Carrier PH13NR036000AEAA the phase-shifted jolt they need to start and the steady torque they need to keep running. It is the single most common failure point in any outdoor unit. When it weakens, the compressor or fan hums but won't start, the unit clicks and trips the breaker, you hear a loud buzz from the contactor area, the fan spins slowly or only after you nudge it, or the system short-cycles on overload. A failed cap often bulges, leaks, or reads far below its rated value. This is a dual run capacitor, commonly 45/5 MFD at 440VAC (verify the exact MFD stamped on your old cap — HERM for compressor, FAN for the fan, C common). OEM capacitors are held to a tight ±5% tolerance and rated for full continuous-duty voltage and temperature. Why OEM matters: cheap aftermarket caps often carry ±10–15% tolerance and lower voltage/temperature ratings. A cap that is even 10% low starves the compressor windings of starting torque, drawing locked-rotor current that overheats and shortens the life of the most expensive part in the system. Correct MFD is not optional — wrong capacitance stresses the compressor windings and burns them out. Install difficulty: 1 of 5 — the easiest common repair. Tools: 1/4" nut driver, insulated needle-nose pliers, and a multimeter with capacitance mode to confirm the new reading. #1 safety warning: ALWAYS discharge the capacitor across its terminals with an insulated screwdriver or 20k-ohm resistor before touching it — a charged run cap can deliver a dangerous shock minutes after power is off. Photograph the wiring first. Ships same business day from our stocked warehouse on orders 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 PH13NR036000AEAA. 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.
