What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY2PEB060090AB 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 PY2PEB060090AB.

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 PY2PEB060090AB

This is the genuine OEM factory-specified single run capacitor for the Carrier PY2PEB060090AB packaged unit. The run capacitor remains in the circuit continuously during compressor and fan motor operation, stabilizing voltage and ensuring efficient, sustained motor performance. When this capacitor weakens or fails, symptoms include a loud humming or buzzing at startup with no motor movement, a fan motor that spins sluggishly or not at all, or a unit that short-cycles and trips on thermal overload. Don't let a failed $15 part take down your entire system — this is one of the most common and straightforward fixes in HVAC service.

Specs: 4 MFD (microfarad) | 370 VAC | Oval case | ±5% capacitance tolerance | 50/60 Hz | Part Numbers: P291-0403, P291-1003, P291-2503
OEM vs Generic: This is a genuine Carrier / Totaline OEM capacitor, tested to 60,000 service hours with 100% electrical testing at the factory. Generic capacitors often carry ±10% MFD tolerance, which accelerates motor winding stress and shortens compressor life — especially critical in a packaged unit where heat buildup is concentrated.
Install difficulty: 2/5 — Discharge the capacitor fully before touching any terminals (use a 20kΩ resistor or insulated screwdriver). Tools needed: ¼" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring before disconnecting terminals. Power must be locked out at the disconnect before beginning.
Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct factory replacement for Carrier model PY2PEB060090AB. Cross-references and supersedes part numbers P291-0403, P291-1003, P291-2503, 97F5704, HC90AA004, HC91CA004, and HC90AB004. Always verify the MFD rating and voltage on your unit's data plate before ordering — voltage rating must match or exceed the original. Questions about fitment? Our HVAC parts specialists verify compatibility before you order. Order by 5 PM and it ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY2PEB060090AB?

Yes. This is the factory-specified OEM capacitor for the Carrier PY2PEB060090AB. 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 PY2PEB060090AB?

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?
