• 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.

Soft starter saves compressor.

He has low opinion of Lennox.
