Why Every Tech Should Read Schematics
What are the benefits and advantages of actually utilizing a s- a schematic diagram, understanding it? So first and foremost, accurate diagnostics. Anytime that you diagnose something properly, right, you measure the resistance, voltage, all of that information, you're actually pinpointing the root cause of the failure, which in the long, long run, it's gonna actually save you time, right?
A lot of technicians, you know, they contact me, they're like, "Hey, Juan, you know, I don't, I don't need to troubleshoot. I could just swap out a part, and most of the time it works." And while that may be the case in certain instances, uh, for the most part, if you don't troubleshoot and you just shotgun it, there's a very high probab- probability that you're not gonna get the right part the first time.
So if you troubleshoot, you're actually saving time because you'll have the certainty of what it is that's wrong with the appliance, and that allows you to get the right part every single time. So that's kind of one of the first advantages that I wanted to mention over here, my friends. And of course, um, the second major point is safe service practices, okay?
When you're working with electricity, obviously there's gonna be a lot of, uh, areas of high voltage or even points in, you know, on the board or, or in the appliance where you could potentially cause damage, right? So by leveraging the schematic diagram, you're a- you're actually able to identify where those live circuits are and also help you prevent damaging something.
And I'll give you a perfect example in a couple minutes when we, uh, dive into, um, the, the, the actual circuitry, the actual schematic diagram for this front load washer we're gonna be demonstrating today. Now, the last thing, my friends, is of course consistent workflow. And what I mean by that is when you, when you have a consistency in, in how you do things, right, you're able to establish a standardized repair procedure.
So for example, as a technician when I w- when I was doing this years ago, what I would often do is, let's say I had a dead washing machine, right? The display's dead, nothing's working. The first thing I would check is the AC outlet. Make sure that there's voltage coming from the AC so that from that point on, I know that, you know, there's AC at the outlet, everything should be okay after that, and then I could pinpoint exactly where the, um, where the open circuit was.
So if you, if you establish a standard procedure, you make it almost a habit to follow good, um, how could I say, like a good consistent workflow every single time, right? So that's why it's important to, to utilize the schematic diagrams because this doesn't just work for washers, right? What I'm gonna show you today can actually be applied to any, any appliance out there.
So obviously this is gonna help you improve your repair quality and it builds customer trust as well.
