You are one lucky lady to have caught that! I think there is something worng with the Rowenta, I've had two Rowenta irons go on me….they became very, very hot, then wouldn't cool down, then refused to go on again when plugged in! And they were both the expensive ones! You are right to warn everyone to be cautious…..we quilters use irons as a MAJOR tool. We can't be careful enough….!
