A run capacitor is an energy-saving device that is in the motor circuit at all times. If a run capacitor fails, the motor can display a variety of problems including not starting, overheating, and vibrating. A bad run capacitor deprives the motor of the full voltage it needs to operate correctly.
Visual Clues: Physical damage to the capacitor’s casing, such as cracks or splits, is a clear sign of a problem. This can be due to mechanical stress, overheating causing the casing to burst, or manufacturing defects.
The motor may exhibit signs of sluggishness, uneven operation, or intermittent stalling, indicating a capacitor issue. Excessive heat generation in the motor or capacitor area can signal a malfunctioning capacitor.
In this comprehensive guide, we will delve deeper into the symptoms of a bad motor capacitor and explore the steps to address them effectively. One of the primary indicators of a defective motor capacitor is the motor's inability to start or a delayed start-up.
If you notice that a run capacitor seems “swollen” that’s a bad sign, and some can actually split open in extreme cases. When the capacitor appears to be intact and in good form, the next step is to remove the capacitor from the system for testing, a process you can follow in this guide.
A: A start capacitor requires a high amount of energy to produce enough torque to kick start motors in an AC system. Q: What happens if the wrong size run capacitor is used? A: It will cause a variety of problems and cause undue stress on the motor including overheating or a reduction in speed.
