I had the same problem with my dryer. Checked all the diagnostics that came with the dryer and everything was O'K. Replaced the circuit board and the dryer still would not run without holding the button in. Just for the heck of it switched the motor relay with the heat relay and the dryer ran without holding the button in. The continuity test showed the relay to be in working order and it wasn't. {text removed by admin, reason: site policy} Hope this helps you out. Karen
