What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model N6A48NG481457 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 N6A48NG481457.

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 N6A48NG481457

This is the OEM-specified run capacitor for the draft inducer motor assembly on the Carrier N6A48NG481457 gas furnace. The draft inducer motor capacitor provides the precise starting torque and continuous run support required to spin the inducer blower — the component that purges combustion gases before and during each heating cycle. When this capacitor fails, the inducer motor will hum without spinning, run sluggishly, or fail to prove sufficient negative pressure to close the pressure switch, resulting in a no-heat lockout condition. Referenced under OEM part numbers 50HE400792 (Draft Inducer Motor Assembly w/ Capacitor) and HC30CL461 (Draft Inducer Motor w/ Capacitor), this capacitor is the factory-matched replacement to restore full inducer performance without replacing the entire motor assembly.

Specs: OEM-matched MFD and voltage rating | Factory tolerance ±3% | Designed for inducer motor run-circuit duty | Replaces capacitor component within assemblies 50HE400792 and HC30CL461
OEM vs Generic: OEM capacitors are wound to exact factory MFD tolerances, protecting the inducer motor bearings and windings from the stress of under- or over-capacitance. Generic alternatives often run ±10% tolerance, which can shorten inducer motor life and cause nuisance pressure switch faults.
Install Difficulty: 2/5 — Disconnect power and verify zero voltage before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring and terminal connections before removal. Discharge any residual voltage from the old capacitor prior to disconnecting leads.
Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier N6A48NG481457 gas furnace draft inducer motor circuit. Verify your existing capacitor's MFD and voltage ratings against your unit's data plate and inducer motor nameplate before ordering. Cross-references OEM part numbers 50HE400792 and HC30CL461. Have your model and serial number ready — our fitment team is available to confirm compatibility before you order.

Frequently Asked Questions

Does this Capacitor fit my Carrier N6A48NG481457?

Yes. This is the factory-specified OEM capacitor for the Carrier N6A48NG481457. 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 N6A48NG481457?

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.
