What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model N6A48NG481814 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 N6A48NG481814.

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 Draft Inducer Motor Capacitor for Model N6A48NG481814

This is the factory-specified OEM run capacitor for the draft inducer motor assembly on the Carrier N6A48NG481814 packaged gas/electric unit. The draft inducer motor capacitor provides the starting and running torque required to spin the inducer blower, which evacuates combustion gases and proves airflow before ignition begins. When this capacitor fails, the inducer motor will hum without spinning, run sluggishly, or draw excess current — triggering a pressure switch fault and preventing the furnace from ever reaching the ignition stage. Cross-references OEM part numbers 50HE400792 and HC30CL461.

Specs: Factory-matched MFD rating for Carrier N6A48NG481814 inducer motor | 370V or 440V rated (verify on motor data plate) | Designed for continuous duty inducer motor use | Meets OEM ±5% capacitance tolerance
OEM vs Generic: This OEM capacitor is wound to Carrier's exact factory specification. Aftermarket capacitors often ship with loose ±10% tolerances that cause inducer motor overheating, premature bearing wear, and repeat failures — especially on draft inducer assemblies that run at sustained high temperatures near the heat exchanger.
Install Difficulty: 2/5 — Discharge the capacitor fully before handling. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (capacitance mode to verify before install). Always photograph the original wiring orientation before disconnecting terminals. The capacitor is typically mounted directly on or adjacent to the inducer motor housing.
Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered for the Carrier N6A48NG481814 packaged unit draft inducer motor assembly. Confirm your existing capacitor's MFD and voltage ratings on the motor data plate or original capacitor label before ordering. Cross-references OEM part numbers 50HE400792 and HC30CL461. Not sure it fits? Our HVAC parts team will verify compatibility before you place your order — just reach out.

Frequently Asked Questions

Does this Capacitor fit my Carrier N6A48NG481814?

Yes. This is the factory-specified OEM capacitor for the Carrier N6A48NG481814. 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 N6A48NG481814?

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?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
