Dryer runs OK but stops randomly ,will start again if I push start button. Sometimes drum will continue roll if door opened ,did this with old switch and new one. All other functions of dryer work perfectly,heats ,reverses etc just randomly stops. would try a new timer if you thought that might help,I assume the door switch is linked to timer ,as this is the only program function I can find on machine,Hotpiont CTD00p hope you can help with advice
