New Timer not working.

Model Number: NGD4700YQ2
Brand: Amana
Age: 6-10 years

Is there a reason a new timer might not move? It was a pain to take out the old one so I am hoping to avoid taking it out again if I can.

I cannot find a wiring diagram for this unit so cannot help.

I would check that the timer is not advancing in both timed and auto modes.

Timed is usually a direct hook up but auto uses a different circuit/set up.
