I changed my water about 2 weeks ago.... haven't used it since. It heated up just fine. I went out to check on it today, we've had some major winds and I never strap down the cover. I noticed the cover was crooked... so I checked the water and whatnot. It was only 91. At first I thought maybe it was cause we've been cooler than norm and the cover wasn't on right/tight... but then I realized it was more than that. I went and checked the disconnect and noticed the one on the right was tripped. I flipped it over and now the tub is heating. Should I be concerned?
