Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Was the new timer part number 37001251? If so it is the correct timer if not what number did you get?
Okay so you had no heat anywhere not in the timed or sensor dry positions? Who told you that you needed the timer? Why did you need to replace this? Somebody tell you that was the problem? This is a gas dryer am I correct?
