What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH1REA048000AAWB 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 PH1REA048000AAWB.

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 15 MFD 370V for Model PH1REA048000AAWB

This is the factory-specified OEM single run capacitor for the Carrier PH1REA048000AAWB packaged heat pump unit. The run capacitor maintains the continuous phase-shifted current that keeps the condenser fan motor or compressor spinning at rated speed. When this capacitor weakens or fails, you'll typically notice symptoms like the motor humming but not starting, the system short-cycling, warm air from a cooling system, or a hard-shutdown fault with no cooling output. Replacing it with the correct OEM-spec part restores factory efficiency and protects motor windings from premature wear.

Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | UL-approved current interrupter | Non-PCB dielectric fluid | OEM Part No. P291-1503
OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact ±5% MFD tolerance. Generic capacitors often ship at ±10% or wider tolerances, causing motor amperage imbalance, accelerated bearing wear, and shortened compressor life — especially critical in packaged rooftop applications like the PH1REA048000AAWB.
Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before touching terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before removal. The capacitor typically mounts in the control/electrical compartment of the packaged unit.
Warranty: 1-year OEM manufacturer warranty. Orders placed before 3 PM local time ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PH1REA048000AAWB packaged heat pump. Always confirm the MFD rating and voltage stamped on your existing capacitor's label before ordering — mismatched specs can damage motor windings. Have questions about fitment? Our HVAC parts specialists verify compatibility before you buy. In stock — ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH1REA048000AAWB?

Yes. This is the factory-specified OEM capacitor for the Carrier PH1REA048000AAWB. 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 PH1REA048000AAWB?

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?
