OEM Carrier Run Capacitor for PH13NR03600GAHAA Heat Pump Unit

The run capacitor supplies the steady phase-shifted current that keeps your condenser fan motor and compressor running efficiently after start-up. When it loses capacitance or fails outright, you'll hear the outdoor unit humming without starting, see the fan blade struggle to spin (or only turn if nudged), feel warm air at the registers, trip breakers, or watch the compressor short-cycle on its overload. A domed, bulging, or leaking top on the existing cap is a clear visual sign. This is a dual "round can" run capacitor wired to both the HERM (compressor) and FAN terminals. Units in the PH13NR036 (3-ton) class typically use a rating in the 35/5 MFD range at 440 VAC, held to a precise OEM tolerance of ±5%. Read the microfarad and voltage values stamped on the side of your original capacitor and match them exactly — the dual ratings are not interchangeable between the fan and compressor sides. Capacitance accuracy is critical on this part. Generic aftermarket caps are often built to loose ±10–15% tolerances and drift further with age and heat. A capacitor even a few MFD off-spec under-energizes the compressor windings, increases amp draw, drives winding temperatures up, and shortens the life of the system's most expensive component. The genuine Carrier part holds its rated value through thousands of thermal cycles. Install difficulty: 2 of 5. Tools: 1/4" and 5/16" nut driver, insulated needle-nose pliers, and a multimeter with a capacitance function. #1 safety warning: a charged capacitor can deliver a lethal shock even with power off — open the disconnect and fully discharge the cap across a 20k-ohm resistor or insulated screwdriver before touching the terminals.

Compatibility

This part is compatible with Carrier model PH13NR03600GAHAA. 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.
