Hey y'all! We have been enjoying our pool for about 2 weeks now. We are out almost every night, night swimming and hanging out pool side. So of course we have our pool lights on. We haven't had any problems with them (2) but tonight while inside the house I heard a loud "buzz" "whirring" sound my kids heard it upstairs, it just really echoed. We ran back outside and as soon as we turned the pump off, my husband was able to hear it and the only other thing on was the lights. We turned those off, no sound. We turned them on the super loud buzz came back. It seems to be happening with the turn of the colors. Also we realized it wasn't turning "red" tonight. This is not just a low buzzing sound, we can hear it from the house, it would certainly wake up anyone on the side of the house where the box is. Anyone have any idea what could be happening? We will look more closely in the morning, but i wanted to get this posted tonight. Thanks!!
