What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model Heat Pump PH12NA06000GACAA 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 Heat Pump PH12NA06000GACAA.

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 Run Capacitor for Heat Pump PH12NA06000GACAA

The run capacitor is the workhorse component that keeps the compressor and condenser fan motor of your Carrier PH12NA06000GACAA heat pump running with the proper phase shift and torque. Unlike a start capacitor, it stays energized the whole time the unit operates, stabilizing voltage and current draw. As it degrades, you'll see the outdoor unit buzzing without starting, the fan struggling to spin up, lukewarm air in cooling, frequent short-cycling, or a breaker that trips on startup. A swollen top, rust streaks, or oily residue on the can means it's already failing. Specs: This is a dual round run capacitor measured in microfarads (MFD/µF), serving both the HERM (compressor) and FAN terminals — commonly in the 35–45/5 µF range at 440 VAC on this Carrier condenser. Match the exact MFD values stamped on your current capacitor. OEM parts maintain a precise ±5% tolerance and a 10,000-hour rated service life. OEM vs Generic: With capacitors, the number on the label has to be the number in the circuit. Generic aftermarket units frequently carry ±10–15% tolerance, so capacitance can drift well outside spec. Wrong MFD robs the compressor of starting torque, overheats its windings, and quietly shortens the life of the costliest part in the system. OEM-grade tolerance and voltage rating are cheap insurance for an expensive compressor. Install: Difficulty 2/5. Tools: 1/4" nut driver, insulated needle-nose pliers, and a multimeter for verification. SAFETY — a capacitor stores a lethal charge even after power is off; pull the disconnect AND discharge it across the terminals with an insulated screwdriver before touching any lead. Snap a photo of the wiring first. 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 PH12NA06000GACAA. 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 Heat Pump PH12NA06000GACAA?

Yes. This is the factory-specified OEM capacitor for the Carrier Heat Pump PH12NA06000GACAA. 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 Heat Pump PH12NA06000GACAA?

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.
