What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model Model PH3ANA048000BAAA 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 Model PH3ANA048000BAAA.

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 Dual Round Run Capacitor for Model PH3ANA048000BAAA

The dual run capacitor delivers the steady phase shift that keeps both the compressor and condenser fan motor running smoothly on your PH3ANA048000BAAA packaged heat pump. It is the part that fails most often in an outdoor unit, and the symptoms are unmistakable: a compressor or fan that hums but won't spin up, a fan turning slowly, the breaker tripping the instant the unit calls, warm air from the vents, or repeated short-cycling on the compressor's thermal overload. A swollen, domed, or oil-leaking capacitor top confirms it has failed. This is a dual-rated (HERM + FAN) round run capacitor carrying your unit's factory microfarad (MFD) and voltage ratings — commonly in the 40+5 MFD / 370–440 VAC class — and held to a tight OEM ±5% tolerance so both motors see the exact capacitance they were engineered for. Why OEM matters: with capacitors, the rating is the whole job. Generic aftermarket caps frequently ship at ±10–15% tolerance with cheaper dielectric film. A cap that drifts low on MFD forces the compressor to pull higher amperage, overheating and gradually breaking down the motor windings until the compressor itself fails — a far costlier repair than the capacitor. Install difficulty: 2 of 5. Tools needed: a 1/4" nut driver, needle-nose pliers, and a multimeter with a capacitance function to verify MFD. The #1 safety warning: a run capacitor holds a potentially lethal charge even after power is off — turn off the breaker and disconnect, then discharge both terminals through an insulated resistor before handling. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PH3ANA048000BAAA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.

Frequently Asked Questions

Does this Capacitor fit my Carrier Model PH3ANA048000BAAA?

Yes. This is the factory-specified OEM capacitor for the Carrier Model PH3ANA048000BAAA. 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 Model PH3ANA048000BAAA?

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.
