Why Do Capacitors Fail? (It’s not why you think)

You may have asked “Why do capacitors fail?” and come across many theories as to what causes run capacitors to fail so often. In this video, we review how a run capacitor works and some of the potential causes of failure.

One theory is that a high amp draw on the motor causes compressors to fail. Another is that systems with low charge or dirty condenser coils cause capacitors to fail prematurely. However, it looks like capacitors have a fixed amount of current that can go in and out of them, and they’re more independent than a lot of us realize.
