Broken Dryer

So the after the first time trying to use the dryer, the dryer went right to cool down mode. I tried a timed cycle and it dried just fine. The next time I tried the dryer it was no longer blowing hot air as a new timed cycle was still wet. So time to diagnose it.

Well as the first dryer I've really taken to fix, they are actually really simple machines.

There are about 4 "fuses" to check power and temperature's as safe guards. One, an actual internal fuse for to prevent overloading amp's. The other 3 for "monitoring" the temperature. The manufacturers have made it pretty easy to check if the components are working. You just need to use a multi meter and check for continuity (meaning there are no breaks in the wire.)

After reaching to hard places and checking the components finding they are all working properly. Its time to check the circuit board, or "motherboard." Taking way to long and plugging it back in multiple times, having it work, then not work after I put it all back together. I thought maybe a solder connection was bad, as they sometimes happen with lots of vibration. I found 3 broken solder joints and circled 2 of them as my picture doesn't show the third just an arrow point to it. Oh and I also stuffed that bothersome noise maker (piezoelectric transmitter) full of paper towel to quite it up, though I could have just removed it.

Here you see me soldering one of the joints by adding a little more solder and heating it up so it melts evenly. I found that solder gun a few years ago and having that to solder is like a 1000 times better than what I had before.

I put it all back together and tried the dryer out, and oh so much sweet hot air it was great. ps: don't worry about the hair it helps when its windy outside.
