Went out to help a tech at some town homes. First when I arrived on scene I asked him what was the situation he mentioned the the transformer inside of the air handler was burning out and that this was the second transformer he burned out. Being that I am a detective that was recently armed with combat training as a samurai I quickly begin half splitting to determine what circuit is causing the transformer to push to many amps. Having an understanding of electrical circuitry(thanks to the fundamentals at master samurai tech) I placed a 3 amps fuse in the circuit with the transformer to save it. Then begin to find what thang that was not doing its thang. Isolated the cool circuit going to the outside unit, by the way this is a heat pump. Discovered that the tech had the wrong unit. Elementary my dear Watson is what I wanted to tell him but I thought it was pretty lame. My next move was to locate the culprit that was shorted and pushing too many amps that would cause the transformer to overdose. Not in my neighborhood seen a contactor that looked very suspicious so I questioned him and he only had 9 ohms which I knew from samurai training didn't add up to ohms law allowing to much current to pass. The sta troubleshooting is for more than washer,dryers, or ranges it's universal. I used it to troubleshoot my tie for first love air conditioning. It has made me a better tech in understanding and explanation.
The cool hand
