Thanks for your speedy answer. But looks like you misunderstood my question.
I'm aware of the timer knob is threaded, unscrew counter-clockwise to remove it. But as I stated in my initial question, BOTH TIMER KNOB AND DIAL SPINS FREELY EVEN PUSHED DOWN . the knob pushes in pulls out to on/off, but I just can't turn the timer the way I supposed to do. I'm not sure if the knob is broken or dial, or both are broken. Should I use traumatic force(like hammer and chisel) to release(break) the timer knob? Thanks again for your help.
ANSWER Hello Steve. If the shaft free turns, you, will need to try and use needle nose pliers to hold the shaft while you remove the knob. It would be best to have the timer in the on position, shaft pulled out, to do this. Once removed, the timer must be replaced, and also the knob if damaged. Hope this helps.
