The other day, the big fluorescent light in our garage stopped working. So, being the problem solver that I am, I started looking for the cause.
First things first: had a breaker popped? No.
Since it’s a fixture with two large (8-foot!) fluorescent tubes, I figured it had to be either a bad tube or a bad ballast. (I thought it a little strange that it had failed completely, with no previous signs like slow start up or flickering.)
To save time, I decided to buy new tubes and a new ballast. At Home Depot, they had the ballast, but it was an open package, probably a returned item. But they gave me 10% off, so that was okay. I came home, and although I should have tried just the tubes first, I put in the new ballast and the new tubes and tried the switch.
Nothing.
I was trying to figure what else it could be, when I looked around the garage and noticed that, in addition to the switch by the door into the house, there was another switch by the side door to the outside. (We have lived in this house for less than a year.) I flicked it, and the other ceiling fixture came, and the one that I had been working on flickered briefly and went out.
So the problem had been that it was a three-way circuit with a second switch that I had never used or even realized was there, and that had been accidentally thrown. There was never anything wrong with the fixture. I had spent about $50 and an hour and half or so (including time to buy the replacements) for no reason at all.
:smack::smack::smack:
However, the fact that the fixture didn’t work with the new parts meant that something was still wrong. (If everything had worked, I would have just left it as is, with the new parts in place, keeping the old parts as spares.) But it didn’t work.
So I put the old ballast back, and it worked with the new tubes, except that one of the tubes only lit up for half its length. So the new ballast was bad, as was one of the tubes. I put back the old tubes. Everything was back to status quo ante – old ballast, old tubes – and worked perfectly.
The good news is that although I wasted all that time, at least I can return the new – but, fortunately for me, defective – parts for a refund, and not be out $50.
The last bit of :smack::smack::smack: is that little thing I mentioned above about the other fixture on the ceiling. When the problem arose, I didn’t even notice that there were two fixtures. I saw that the one over where we park our car was out, but didn’t happen to notice that about ten feet away was a second identical fixture, that was also out. If I had, I would have realized that the problem was not with a ballast or tube in that one fixture, and could have spared myself a few hours’ trouble.
I’m a pretty smart guy, and have handled of a lot of home repairs successfully, but every once in a while I wake up stupid.
Please make me feel better: tell me about your :smack::smack::smack: moments around the house.
