The timer was intermittent and not connecting to ignitor

I pulled the dryer away from the wall unplugged it.
I removed the small back panel just behind the timer switch ( 5 screws for 1/4" nut driver)
The switch has one screw (1/4"nut driver ). Remove it and the timer switch comes away. Disconnect the two electrical connections.(impossible to screw this part up). Reconnect the the new switch to the couplings from the old switch. This part really is idiot proof. There's only one way.
The knife is to pry off the plastic dial from the stem of the old timer. Dial was on tight and the broad blade on the butter knife helped from breaking the plastic dial. Everything goes back together the way it came apart. Blissfully simple. I hope that helps. I felt like a real genius when I was done. Good job Partselect! I have 10 cats.
