I have a rack from boaphile it is 5 tubs high, 32 qts and sideways. I have a ranco thermostat. The thermostat is set at 100 (which usually puts the warm side of the tubs at 88-90 degrees, but the tubs are not being heated at all. Everything appears to be plugged in....the thermostat is reading the themperature (like it says that its 77 degrees in there) and it keeps turning on like its trying to raise the temps but its not working. I don't know what to do. I have most of my snakes moved over to my room-mates rack, but two of them could not fit.....any suggestions besides call boaphile (which I'm about to do)??
