The average operational lifespan of a typical ceiling fan motor run capacitor generally ranges between seven and twelve years under normal operating conditions. Capacitors degrade over time due to continuous thermal stress from electrical current, indoor ambient humidity, and routine voltage fluctuations. When a capacitor fails, it loses its ability to store and release the electrical charge required to give the AC induction motor the rotational push it needs. You can troubleshoot capacitor wear easily by checking for a bulging or leaking casing. You can verify that your corrective action is successful when discharging the old unit and replacing it with a new motor capacitor matching the exact microfarad rating restores instant, powerful blade rotation without requiring manual pushes.
