I tried to start my dryer and the Timer/Knob Assembly just came off in my hand. On talking to someone, they said to try to use pliers to turn the stem, and then pull it out; the stem will turn but will neither pull out or push in. Do I need a new timer (which the stem is attached to) or a new knob? The knob seems to be in perfectly good shape; and this part is discontinued. What do you think? Thanks in advance for your help.

I guess it's stress or a sign of age. You're right and thank you; I was getting the washer mixed up with the dryer. Thank's for setting me straight; you're an angel! (Wish everything could be fixed so easily.)
