What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH2PEB048000AA 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 PH2PEB048000AA.

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 7.5 MFD 370V for Model PH2PEB048000AA

This is the factory-specified OEM single run capacitor for the Carrier PH2PEB048000AA packaged heat pump unit. The run capacitor remains in the circuit continuously during compressor and fan motor operation, stabilizing voltage and ensuring efficient motor performance. When this component fails, you'll typically experience symptoms such as a humming or buzzing sound with no motor startup, the unit blowing warm air, or the system short-cycling shortly after startup. Left unaddressed, a weak or failed capacitor forces motors to work harder, accelerating wear on the compressor and condenser fan motor.

Specs: 7.5 MFD (microfarad) | 370V rated | Oval case form factor | OEM part number P291-0753 (superseded by P291-0754) | Also covers P291-1503 (15 MFD 370V oval, superseded by P291-1504) — verify your unit's data plate rating before ordering
OEM vs Generic: Genuine Carrier OEM capacitors are factory-tolerance matched (±5% MFD). Generic aftermarket units commonly run ±10% or worse, which causes motors to draw excess current, shortens compressor life, and can void equipment warranties.
Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before opening the unit. Allow 5 minutes for the capacitor to self-discharge, then use an insulated screwdriver to short the terminals before handling. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting terminals.
Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier PH2PEB048000AA packaged heat pump units. Note that Carrier sources capacitors from third-party manufacturers such as Genteq/GE — the label on the capacitor will reflect the capacitor manufacturer's name, not Carrier. Cross-references include HC91CA007 and GE/Genteq 27L566 for the 7.5 MFD variant. Always verify the MFD and voltage rating on your unit's data plate before ordering. Have a fitment question?

Frequently Asked Questions

Does this Capacitor fit my Carrier PH2PEB048000AA?

Yes. This is the factory-specified OEM capacitor for the Carrier PH2PEB048000AA. 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 PH2PEB048000AA?

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?
