Do it Yourself A/C Repair

If I were to rate the most frustrating part of my life for this year (2012), it would be our Air conditioning unit in our home. I’ve had a crash course in do it yourself a/c repair since we owned the home from clogged drain lines to a defective door squat switch.

The latest thing I’ve been chasing is an electrical connection problem. Often, I would get up in the morning and Janna would tell me that the a/c doesn’t work. I found out after several trips to the attic that if I moved a certain wire bundle inside the A/C unit it would turn on.

At first the a/c would turn on and stay on for several weeks. Each time I did this though I found the cycle would get shorter; it would work for a week, then a few days, then only a few minutes. I found myself at a point where I needed to fix this permanently. I don’t really like to hire people to do things until I’ve exhausted my knowledge about it.


Luckily, after doing some snooping around I saw something that didn’t look right. Turns out it was a broken solder joint on the fan control circuit board. I had to buy a soldering iron to fix it. Soldering is definitely an art to some degree; it’s a lot like welding and requires a steady hand, which I don’t have. It seemed like the circuit board was a moving target; it took a little getting used to.

You can see the crack in the solder a little better in this picture than in the video.

It may not look the prettiest but it’ll work.


It took me a while to re-solder the terminal and make it look presentable to the viewing public. : ) In the end I ended up saving $65, not bad.

The next thing on my to do list is to straighten the fins on the a/c compressor, this should save us some money during the summer months because it will increase efficiency. Too bad I’m waiting to do this at the end of summer. : ( Have you ever fixed an a/c problem yourself? Please tell us about it in the comments section below.

    This is way cool! Soldering is tricky, but looks like you got it down better than I have so far. Nice flashlight too.

      Thanks Derek! I think it’s a stretch saying I have soldering down yet. I only let you see what I wanted you to see. : ) Janna already wants me to fix a piece of jewelry now so we’ll see how that goes. I got the flashlight last christmas and use it for everything, the tripod feature it extra handy.

    Watch out! You are following the path of my super-handy hubby. He may be semi-retired now, but you wouldn’t know it. He works his flights and in-between those, he is at someone ELSE’s house doing handy work.
    With that said, I am very grateful that he has been so talented/gifted in this area and that he doesn’t mind sharing those skills with others.
    If you ever get stuck, give him a call. He rarely can’t find a solution.

      I got that impression the first time we met. I will definitely give him a call when I get stuck, I only have a basic understanding of air conditioners, only enough to be dangerous. 🙂 I mostly call for help when I get into more complicated high risk electrical stuff. Thanks for the compliment and offer.
