What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model LC348TM402018 — HC30GB23 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 LC348TM402018 — HC30GB23.

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 LC348TM402018 (HC30GB230)

This is the OEM factory-specified run capacitor for the draft inducer motor assembly in the Carrier LC348TM402018 furnace. The draft inducer motor capacitor provides the electrical phase shift needed to start and sustain the inducer blower motor — the critical first step in every heating cycle. When this capacitor fails, the inducer motor will hum without spinning, run sluggishly, or fail to start entirely. Because the furnace control board requires proof of inducer operation before opening the gas valve, a failed capacitor causes a complete no-heat lockout, often accompanied by a pressure switch fault code. This OEM replacement (part number HC30GB230) restores factory performance and clears those fault codes without costly motor replacement.

Specs: OEM-matched MFD rating and 370V/440V voltage rating | Designed specifically for the draft inducer motor on the LC348TM402018 | Round case design | Factory ±3% tolerance for precise motor protection
OEM vs Generic: This is a genuine Carrier OEM capacitor matched to the HC30GB230 inducer motor assembly. Generic capacitors with loose ±10% tolerances can cause inducer motor overheating, premature bearing failure, and repeat breakdowns — costing far more in labor than the savings on the part.
Install difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify capacitance before and after). Always photograph original wiring before disconnecting. Turn off power at the breaker and the furnace disconnect switch before beginning.
Warranty: 1-year OEM factory warranty against defects. Ships same business day from our climate-controlled parts warehouse.

Compatibility: Engineered for the Carrier LC348TM402018 furnace draft inducer motor assembly (OEM part HC30GB230). Always verify your existing capacitor's MFD and voltage rating against your unit's data plate before ordering. Not sure about fitment? Our HVAC parts specialists verify compatibility before you buy — no guesswork, no return hassle. Order by 3PM local time and your part ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier LC348TM402018 — HC30GB23?

Yes. This is the factory-specified OEM capacitor for the Carrier LC348TM402018 — HC30GB23. 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 LC348TM402018 — HC30GB23?

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?
