What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY3PEA048130NA 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 PY3PEA048130NA.

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 PY3PEA048130NA

This is the factory-specified OEM single run capacitor for the Carrier PY3PEA048130NA packaged unit. Run capacitors store and continuously release the electrical charge needed to keep the condenser fan motor or blower motor running at peak efficiency. When this capacitor weakens or fails, the motor it supports will struggle to start, run hot, draw excess amperage, or fail to run entirely — often leaving your system blowing warm air or shutting down on thermal overload.

This listing covers both OEM part numbers used on this unit: P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V). Verify the MFD rating printed on your existing capacitor before selecting. Mixing MFD ratings will damage motors — always match exactly.

Specs: Single run capacitor | Oval case | 370 VAC rated | Available in 4 MFD (P291-0403) and 15 MFD (P291-1503) | ±5% capacitance tolerance | 50/60 Hz
OEM vs Generic: These are genuine Carrier/Totaline OEM capacitors, tested to 60,000 service hours with 100% electrical testing at the factory. Generic capacitors often run at ±10% tolerance, accelerating motor bearing wear and shortening equipment life.
Install Difficulty: 1/5 — One of the simplest HVAC repairs. Discharge the capacitor fully before touching terminals (use a 20,000-ohm resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph terminal wiring before disconnecting.
Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PY3PEA048130NA packaged units. Always verify the MFD rating and voltage on your existing capacitor's data label before ordering — do not substitute a different MFD value. Questions about fitment? Our HVAC parts specialists verify compatibility before you order. Order now — in stock and ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA048130NA?

Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA048130NA. 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 PY3PEA048130NA?

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?
