I have a Hayward H150 heater and the rocker switch needs to be replaced. It was not working early in the season and we had a plumber look at it. He replaced some parts and it was working for a little while, then it stopped working. We didn't need to use the heater during the summer because with the solar cover, we were just fine. However, I wanted to get this thing fixed and ready for next season. My brother-in-law who is an electrician found that the rocker switch is faulty and needs to be replaced. Does anyone here know where I can find this part? I tried our local pool store and they did not carry it nor could they order it for me. Any help would be greatly appreciated. Thanks.
