What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PG8UAA024045ADJA 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 PG8UAA024045ADJA.

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 PG8UAA024045ADJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8UAA024045ADJA gas furnace. The run capacitor stores and releases the precise electrical charge needed to keep the blower motor running at steady speed and peak efficiency. When this capacitor fails, you'll typically notice symptoms such as the blower motor humming but not starting, intermittent fan operation, or the motor running slower than normal — all of which can lead to reduced airflow, overheating, and eventual motor burnout if left uncorrected.

Specs: 7.5 MFD (microfarad) | 370V rated (440V-rated replacements are acceptable upgrades) | Oval case | OEM part number P291-0753 | Cross-references: HC91CA007, GE 27L566
OEM vs Generic: This is the genuine Carrier-sourced capacitor built to exact factory MFD tolerance (±5%). Generic capacitors often carry wider tolerances (±10%), which can accelerate motor wear and shorten the service life of your blower motor.
Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify discharge and confirm MFD before install). Photograph all wiring connections before disconnecting the old unit.
Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for use in the Carrier PG8UAA024045ADJA gas furnace. Always verify the MFD rating and voltage on your unit's data plate before ordering — the voltage rating of the replacement must be equal to or higher than the original. Questions about fitment? Our HVAC parts specialists confirm compatibility before you order — no guesswork.

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.
