OEM Carrier Dual Run Capacitor for PY1REA036074ABWA Gas Furnace

The run capacitor in your Carrier PY1REA036074ABWA provides the constant phase shift the blower (and/or inducer) motor needs to run smoothly and efficiently after start-up. It stores and releases energy on every AC cycle to keep the motor's run winding in proper electrical phase. As a capacitor weakens it loses microfarads, and the motor it drives begins to struggle — you'll hear humming, notice the blower running slow or hot, find it cutting out on its thermal overload, or see the motor fail to start at all (just a hum and then nothing). A bulged or leaking top on the can is a dead giveaway. This is an oil-filled motor-run capacitor rated in microfarads (MFD/µF) at a specific voltage (commonly 370V or 440V for this class of furnace motor). The OEM holds a tight ±5% tolerance on its rated capacitance — for example a 7.5 MFD part stays within 7.1-7.9 MFD across its life. Why OEM matters: capacitor tolerance directly determines motor health. Generic aftermarket capacitors are often built to a loose ±10-15% spec, so a part stamped 7.5 MFD may actually deliver 6.4 or 8.6 MFD. Wrong capacitance forces the motor windings to run hot, drawing excess current and shortening the motor's life or burning it out. OEM holds the rating that protects the motor. Install difficulty: 2/5. Tools: 1/4" nut driver, needle-nose pliers, and a multimeter with a capacitance setting to verify the reading. #1 safety warning: a capacitor stores a dangerous charge even with power off — kill power at the breaker first, then discharge it across a 20k-ohm resistor (or insulated screwdriver) before touching the terminals. 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 PY1REA036074ABWA. 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.
