Where these warrenty parts that were installed?
Try this and tell me what happens.
hold the "No Heat Dry" button for 4 seconds or more.
Ok then this means that you have a stuck button on the keypad which in this case is the normal. Did they give you a warrenty on the parts at all?
Thats to bad. Also i want you to know that when they use warrenty parts the parts are not bran-new they are repaired for whatever reason and then sent back out. You will have to get a bran-new one im sorry to say.
What you could try is to take a look at the ribbon cable and clean the ends on it then re-install it and see what happens. Give it a shot.
