Well, it must be that time of year, because my Aqualink has blown still yet another temp sensor (this makes the third, about one per year).

At $90 per these things are expensive to replace every year -- does anyone have an idea on alternatives? I'm even thinking I don't need something that has sensor capabilities, just something that will turn the solar on or off (and I'll deal with the rest manually by monitoring the temp of the water myself).

I have no idea why these things are so fragile -- they don't have any moving parts and all are sealed units. Must be made overseas <bg>.
