Ice maker was not making ice

I watched a short video on YouTube and decided that looked SO easy, even I could do it. I'm a 64-year-old female retired government employee. Of course, most things look easy on video and I had my doubts, but for the $129 part, I figured I'd take a chance, and if I could fix it myself, I'd probably save $100 from having an appliance repairman fix it for me. My husband had SERIOUS doubts that I'd be able to do it. BUT, the part arrived and, rather than pull the refrigerator out and unplug it, I shut off the circuit breaker to the fridge...very easy.and turned the water off on the water heater. I removed 3 screws, took out the old unit and put in the new, then tightened the 3 screws. It took a while for the freezer to get cold enough to start the ice maker, but when I heard the water run into the ice maker, I said..."oh, yes, that's what I'm talking about." Then a bit later, I heard the first ice cubes drop in to the tray, and shouted out another round of "oh, yes, that's what I'm talking about." It works like a charm, and I'm so proud of myself for replacing it myself. Since then, a cousin invited me to her house to fix a drainage problem, and a friend asked me to come over and fix a lamp for her. Am I seeing a new career here??
