WHY CAPACITORS FAIL in Air Conditioners! Watch it Break! - YouTube
July 22, 2023 at 8:24:17 AM PDT * - permalink -- 00:00 The video discusses why capacitors fail in air conditioning units.
- 00:30 The presenter demonstrates how to test a capacitor while the system is running, measuring voltage and current for both the compressor and fan motor.
- 01:26 The test results show that both the compressor and fan capacitors are good and within their specified microfarads rating.
- 02:41 The presenter shows that the capacitor has failed, causing both the fan and compressor to stop working.
- 04:11 Capacitors can fail due to overheating, causing the dielectric fluid to expand and press on the capacitor shell, leading to bulging or leaking.
- 05:35 The lifespan of a capacitor is limited, and higher operating temperatures can reduce its lifespan.
- 07:01 Exceeding the voltage rating of the capacitor, lightning strikes, or voltage spikes can damage the capacitor plates.
- 08:38 Corroded or loose connection points can lead to capacitor failure.
- 09:06 Capacitors do not fail due to high current; they control current going to the start winding of the compressor and the outdoor fan motor.
