Answer to Dryer only Blowing cold air, Simple repair, Remove the plate off the back, the onle that looks a bit like a banjo (Bottom left), About 8 screws i think, Ease away from the machine and then remove the 2 screws holding the element in place on the back of this plate, the thermostat is there, On top of the element casing there are 2 connectors, One of them has a little pin hole in it, Push a needle in there gently Until you hear a click, This resets the thermostat, and brings back the hot air. Put it back together and you should be good to go.
