What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY3PNA060115AA 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 PY3PNA060115AA.

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 PY3PNA060115AA

This is the factory-specified OEM single run capacitor for the Carrier PY3PNA060115AA Performance Series packaged gas/electric unit. The run capacitor sustains the phase-shifted voltage required to keep the condenser fan motor spinning efficiently throughout every cooling cycle. When it weakens or fails, the motor loses torque — symptoms include a loud hum with no fan rotation, intermittent shutdowns on hot days, or the unit tripping the high-pressure limit. Left unaddressed, a failed run capacitor forces the motor to draw locked-rotor amperage, rapidly burning out the motor windings.

Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% factory tolerance | 50/60 Hz | Replaces P/N 97F5704, HC90AA004, HC91CA004, HC90AB004. Also cross-references secondary OEM part P291-2503 for blower circuit applications on this model — verify your unit's wiring diagram before ordering.
OEM vs Generic: This genuine Carrier/Totaline capacitor is manufactured to exact factory tolerances and subjected to 100% electrical testing before packaging. Generic aftermarket capacitors are typically rated at a looser ±10% MFD tolerance, which accelerates motor wear and reduces compressor longevity over time.
Install Difficulty: 2/5 — Locate and switch off the unit's disconnect and wait a minimum of 5 minutes for the capacitor to discharge fully before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter capable of reading capacitance. Photograph all wiring connections before removing the old capacitor. Match MFD and voltage ratings exactly to the data plate on your unit.
Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PNA060115AA Performance Series 5-ton packaged gas/electric unit. Always verify the MFD rating and voltage stamped on your existing capacitor against your unit's data plate before ordering. Our team is available to confirm fitment prior to purchase — reach out before you order if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PNA060115AA?

Yes. This is the factory-specified OEM capacitor for the Carrier PY3PNA060115AA. 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 PY3PNA060115AA?

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?
