What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY3PEA042060AA 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 PY3PEA042060AA.

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 for Model PY3PEA042060AA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PEA042060AA packaged unit. A single run capacitor maintains a continuous phase-shifted current to keep either the compressor motor or the fan motor running at peak efficiency after startup. When this capacitor fails, the motor it supports will hum without turning over, draw excessive amperage, overheat, and ultimately trip on thermal overload — or the unit will short-cycle within the first few minutes of operation.

OEM Part Numbers: P291-0403 and P291-1503 — both are factory-authorized single run capacitors for this model. Verify the MFD rating and voltage on your unit's data plate before ordering to confirm which applies to your specific configuration.
OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances (±3% MFD). Generic aftermarket capacitors often carry a ±10% tolerance, which accelerates motor winding wear, shortens compressor life, and can void equipment warranties.
Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter capable of capacitance measurement. Photograph all wiring connections prior to removal.
Warranty: 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA042060AA packaged unit. Cross-reference your existing capacitor's MFD rating and voltage stamped on the label to confirm fitment between P291-0403 and P291-1503. Our parts specialists are available to verify compatibility before you order — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA042060AA?

Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA042060AA. 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 PY3PEA042060AA?

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?
