About the Run Capacitor
A run capacitor stores and releases a charge to start and run the condenser fan motor. If the capacitor is defective, the fan motor might be noisy, overheat, or not run at all, resulting in the unit not cooling. To determine if the run capacitor has failed, inspect the capacitor. If the dual run capacitor is bulging or leaking, replace it.
