OEM Carrier Run Capacitor P291-4554 for Model LC348TM402286 Unit

This OEM Carrier run capacitor (part P291-4554) provides the steady phase shift that keeps the blower and condenser motors running efficiently in your Carrier LC348TM402286 unit. A run capacitor stores and releases energy to maintain torque; when it weakens or bulges, motors draw high amperage, run hot, hum without starting, or fail to come up to speed. A failed capacitor is among the most common HVAC service calls and an inexpensive fix that prevents costly motor damage. This direct-replacement capacitor matches the exact microfarad and voltage rating required for the LC348TM402286, ensuring proper motor performance and long life. Installation takes about 20 minutes: cut power and discharge the old capacitor safely before touching terminals, photograph the wiring, then transfer leads one at a time. Experienced DIYers can handle it; technicians treat it as routine. Genuine OEM specs mean reliable starting and efficient operation. In stock and ships same-day on orders placed before 3PM CST so you can restore cooling or airflow fast.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model LC348TM402286 Unit?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model LC348TM402286 Unit. 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 Model LC348TM402286 Unit?
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?
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.
