This OEM Carrier run capacitor (P291-4554) provides the continuous electrical phase shift your FC4BNB048000AEAA fan coil blower motor needs to maintain full torque and consistent airflow. When a run capacitor weakens, the blower may hum without starting, spin up slowly, overheat, or trip the breaker. This genuine Carrier replacement is built to factory specifications, matching the original microfarad and voltage values so your PSC motor runs cool, quiet, and efficiently. Installation is a moderate DIY task for anyone comfortable around electrical parts: disconnect power at the breaker, discharge the old capacitor safely, photograph the lead positions, and mount the new one in about 15–20 minutes. Verify the ratings stamped on the can before restoring power. A factory-grade capacitor outlasts cheap universal units and protects your motor while keeping efficiency high. We keep this part in stock and ship same-day on orders before 3PM CST, so your air handler is back to cooling fast. Confirmed compatible with the FC4BNB048000AEAA fan coil.
