I fixed my dryer myself

Came home today and found wet clothes in the dryer. Which was weird because earlier, I had found the same load in there wet and just thought I had forgotten to start the dryer. Low and behold, when I stood and watched it, about ten seconds after starting it, it started beeping and gave out an F01 error code.

While googling it, it seemed that the code meant the relay electronics board had failed and needed to be replaced. I thought, I can probably do that, but the board seemed to be more than $150, which is more than the callout fee on our home warranty ($125). But what we most needed was a working dryer!

While looking for the exact price and a source to order the board, I found this video describing a simple fix for a blown solder connection. I unplugged the washer, opened it up, and the board was blown in the exact same spot as in the video. I soldered a jumper in, put it back together, and lo and behold, the dryer runs!

I have an undergraduate degree in electrical engineering, even though it hasn't been my day job in a long time. So I could at least evaluate the plausibility of the fix, and I had the tools and know-how to do the soldering. So definitely not a fix for everyone.

Money is tight right now, so fixing the dryer for $0 (and in half an hour no less) was big for us. Sometimes you need a win, and today was a day I really needed one!

What fixes around the house are you most proud of, saved you some money, or kept a piece of equipment out of the landfill?
