OEM Carrier Run Capacitor for Furnace Model LC350LC400674

Keep your motors running smoothly with this OEM Carrier run capacitor for the LC350LC400674 system. The run capacitor delivers a steady electrical charge that maintains full torque on the blower or condenser motor throughout each cycle. When it weakens, bulges, or fails, you'll notice hard starts, humming, overheating, reduced airflow, and rising energy costs—and a dead capacitor can quickly destroy a costly motor. This genuine Carrier capacitor is rated to the precise microfarad and voltage values your equipment demands, ensuring dependable startup and quiet, efficient operation. Replacement is a moderate job for someone comfortable around electricity: disconnect power, safely discharge the old capacitor, and move the leads to the matching terminals. Choosing an OEM-spec part protects your motor and avoids the premature failures common with poorly matched generics. Order before 3PM CST and it ships the same day. Trust NationalHVACParts.com for genuine Carrier replacement parts that keep your HVAC system performing at its best, season after season.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Furnace Model LC350LC400674?
Yes. This is the factory-specified OEM run capacitor for the Carrier Furnace Model LC350LC400674. 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 run capacitor on my Carrier Furnace Model LC350LC400674?
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 run 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 run 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?
