What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model YAC48110YAC103AT 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 YAC48110YAC103AT.

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 YAC48110YAC103AT

This OEM single run capacitor is the factory-specified replacement for the Carrier YAC48110YAC103AT packaged unit. A single run capacitor maintains a continuous phase-shifted current to keep the motor running at peak efficiency after startup. When this capacitor fails, you'll typically notice symptoms such as a humming unit that won't fully start, a compressor or fan motor that short-cycles within minutes, or a system that trips on high-pressure lockout due to a struggling motor. Replacing a worn or failed capacitor promptly prevents costly downstream damage to your compressor.

OEM Part Numbers: P291-0753 | P291-4504 — both are factory-authorized replacements for the Carrier YAC48110YAC103AT; verify your unit's data plate for the exact MFD and voltage rating before ordering.
OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances (typically ±3% MFD), ensuring optimal motor performance and longevity. Generic alternatives often carry a ±10% tolerance, which can accelerate motor winding wear and shorten overall equipment life.
Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter capable of capacitance testing. Photograph all wiring connections before removal.
Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier YAC48110YAC103AT packaged unit. Always cross-reference the MFD value and voltage rating printed on the original capacitor or the unit's data plate to confirm fitment. Need help verifying your part? Our HVAC specialists confirm fitment before you order — no guesswork.

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.
