What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PG9MAA024040ADKA 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 PG9MAA024040ADKA.

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 3 MFD 250V for Model PG9MAA024040ADKA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAA024040ADKA two-stage 96% AFUE gas furnace. Carrying OEM part numbers HC91PD001 and P291-0753, this rectangular 3 MFD 250V capacitor is mounted in the furnace's blower section and provides the sustained electrical charge that keeps the indoor blower motor running at proper speed. When this capacitor weakens or fails, you'll typically notice a humming blower motor that won't spin up, intermittent blower operation, motor overheating, or a blower that runs sluggishly — all symptoms that can trigger nuisance lockouts and reduced heating efficiency in your two-stage system.

Specs: 3 MFD (microfarad) | 250V rated | Rectangular case | ±5% tolerance | 50/60 Hz | CSA listed — exact factory replacement dimensions: 1.10" H × 0.87" L × 0.94" W
OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact factory tolerance of ±5% MFD. Off-brand generic capacitors frequently run ±10% or wider, placing added stress on blower motor windings and shortening motor life — a costly consequence on a high-efficiency two-stage furnace.
Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Discharge the capacitor terminals using an insulated resistor before touching any leads. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph or label wire positions before removing the old capacitor.
Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Engineered for the Carrier PG9MAA024040ADKA two-stage 96% AFUE gas furnace. Cross-references include OEM part numbers HC91PD001 and P291-0753. Always verify the MFD rating and voltage on your existing capacitor's label or unit data plate before ordering to ensure a correct match. Our parts specialists are available to confirm fitment — reach out before you order if you have any questions.

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.
