So, pool was opened on Tuesday last week. Due to my schedule, I didn't get a chance to kick on the heater to make sure everything was working properly. Well, I tried today as I was hoping for a little spa time. Unfortunately, after several attempts where I was first getting a simple AGS error (had this last year which turned out to be simply that it took a while for the gas to get down the line (about 250 feet from the meter). Now I have an Air Flow Sw error showing up....so nothing goes on. I guess the good news is that all the equipment is covered for 3 years under the PB, so I've called them. However, I'm wondering if this wasn't going to be under warranty, how pricey this could be to repair.
