Now there's one signal, okay, that I'm gonna mention right here, and it is gonna be a white cable 'cause it's labeled W, and that is gonna be the speed feedback. And that signal comes back from the inverter board to the main control board. It actually starts at the hall sensor in the motor and then goes through the inverter and back at the main.
What this signal does, my friends, is it co- is it... What it does is it constantly tells the main control board if the motor is spinning, how fast it's spinning, or if it's agitating, or if it's going out of control. And the reason this is important is because that is your, that is the main control board's way of monitoring the performance of the motor.
That's your RPM signal. And I'll show you later on how you can leverage SmartHQ service to actually, uh, read that, that, that RPM because unfortunately, with your multimeter, with your, the tools that you have, you're not gonna be able to do this. Even if you can read the schematic, there's no physical way that you can measure that with a multimeter.
But, uh, it is important for you to understand that that signal is, is critical because without it, you're gonna get some kind of a fault code that essentially, um, the end result is that the motor can't spin or agitate
