What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY2PPB060115AB is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number PY2PPB060115AB.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060115AB

This is the genuine OEM Carrier single run capacitor factory-specified for the Carrier PY2PPB060115AB packaged unit. Unlike a dual run capacitor, the single run capacitor remains in the circuit continuously throughout motor operation, stabilizing voltage and ensuring efficient, reliable motor performance. When this capacitor fails, you'll typically experience a humming or buzzing sound with no motor movement, a fan or blower that fails to start, or a unit that short-cycles and shuts off shortly after attempting to start. Prompt replacement prevents secondary motor damage caused by locked-rotor current draw.

Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% capacitance tolerance | 50/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, and P291-2503
OEM vs Generic: This is a genuine Carrier Totaline-branded OEM capacitor manufactured to factory tolerance specifications, built with high-grade metallized polypropylene film and 100% electrically tested before shipment. Generic alternatives often ship with ±10% MFD tolerance, which accelerates motor wear and can void equipment warranties.
Install difficulty: 2/5 — Always shut off power at the disconnect and allow 5 minutes for residual charge to dissipate before touching terminals. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter (for verification). Photograph all wiring connections before disconnecting the old capacitor.
Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse — order before 3 PM local time for guaranteed same-day dispatch.

Compatibility: Engineered for the Carrier PY2PPB060115AB packaged unit. Always cross-reference the MFD and voltage rating on your unit's data plate before ordering — voltage rating must match or be higher (e.g., a 440V-rated capacitor is acceptable in a 370V application). This part also cross-references OEM numbers P291-1003 and P291-2503. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.

Does this Capacitor fit my Carrier PY2PPB060115AB?

Yes. This is the factory-specified OEM capacitor for the Carrier PY2PPB060115AB. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the capacitor on my Carrier PY2PPB060115AB?

Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.

My AC hums but won’t start. What part do I need?

An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).

Is this capacitor compatible with Bryant or Payne too?

Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Carrier capacitor?

OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.

How fast does National HVAC Parts ship?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
