What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model LC3:50LC400677 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 LC3:50LC400677.

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 LC3:50LC400677

This is the factory-specified OEM run capacitor designed for the draft inducer motor assembly on the Carrier LC3:50LC400677 furnace. The draft inducer motor capacitor provides the phase-shifted electrical charge required to start and sustain the inducer blower — the component responsible for venting combustion gases before and during the heating cycle. When this capacitor fails, the inducer motor may hum without spinning, fail to reach operating speed, or prevent the pressure switch from closing, causing the furnace to lock out before ignition ever occurs. Replaces OEM part numbers HC30CK235 and HC30CR230.

Specs: Factory-matched MFD and voltage rating for Carrier LC3:50LC400677 draft inducer motor | Round or oval case per OEM spec | Tight ±5% tolerance for reliable motor performance
OEM vs Generic: This OEM capacitor is manufactured to exact Carrier factory tolerances. Generic alternatives often run outside ±10% MFD, which stresses inducer motor windings, accelerates bearing wear, and shortens overall motor life — leading to costly motor replacement rather than a simple capacitor swap.
Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter for verification. Always photograph existing wiring before disconnecting. The capacitor is typically accessible after removing the furnace access panel and locating the inducer motor assembly.
Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model LC3:50LC400677 furnaces equipped with the HC30CK235 or HC30CR230 draft inducer motor assembly. Always verify the MFD and voltage rating on your existing capacitor or motor data tag before ordering to ensure an exact match. Our parts specialists are available to confirm fitment — order with confidence and get your furnace back online fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier LC3:50LC400677?

Yes. This is the factory-specified OEM capacitor for the Carrier LC3:50LC400677. 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 LC3:50LC400677?

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?
