I had really good intentions of making the change, and installing the new one myself. I even attempted it 3 times. (By attempt I mean took it out of the package, read the instructions, popped the top off the old one, and then stared at the insides for about 20 minutes before realizing that I had absolutely no idea what I was doing. I promptly placed it back in the package each time.
Now we`re a little greener and much more efficient over at our house!
