What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH1REA120000AAWA 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 PH1REA120000AAWA.

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 Heat Pump Dual Run Capacitor for PH1REA120000AAWA

The dual run capacitor in your Carrier PH1REA120000AAWA heat pump delivers the stored phase-shifted current that both the compressor and the condenser fan motor need to start and run smoothly. It is the most failure-prone component in the outdoor unit. When it goes weak or dead, you'll hear the condenser hum loudly while the fan refuses to turn, the compressor may struggle and trip the breaker, the system blows warm air, or the unit short-cycles on and off. A swollen, domed, or oil-leaking top confirms a blown capacitor. This is a dual-rated round capacitor — on a unit this size commonly 45/5 or 40/5 MFD at 440 VAC (a 440V cap is fully compatible with 370V positions) — held to a tight OEM tolerance of ±5%. The "HERM" terminal serves the compressor, "FAN" serves the condenser motor, and "C" is common. Always confirm the MFD and voltage printed on your existing capacitor before ordering. OEM is especially important for capacitors. Budget aftermarket units routinely run ±10–15% tolerance with cheaper dielectric material. A cap drifting even slightly off its rated MFD under-energizes the compressor windings, forcing them to draw extra amperage, overheat, and fail prematurely — turning a small repair into a compressor replacement. Genuine Carrier-spec capacitors hold their value across years of heat cycling. Install difficulty: 2 of 5. Tools: 1/4" nut driver, insulated screwdriver, needle-nose pliers, and a multimeter with capacitance mode. #1 safety warning: capacitors store a lethal charge even after power is off — discharge across the terminals with an insulated screwdriver or 20k-ohm resistor before touching any lead. 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 PH1REA120000AAWA. 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 PH1REA120000AAWA?

Yes. This is the factory-specified OEM capacitor for the Carrier PH1REA120000AAWA. 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 PH1REA120000AAWA?

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.
