Rocker switch that controls vent fan would not work

First I removed the burner control knobs by pulling them off. Then I removed the screw washers from around the burner control stems. I lifted the chrome plate from around the burner stems. I disconnected the wire plugs from the rocker switch control. I made a note of which one was plugged to what (color coded). I removed holding washers from the two screws on the switch. Then I unscrewed the small screws that hold in the rocker switch and removed the old switch. I screwed in the new switch, put on the new holding washers, plugged the wire plugs back in, replaced the chrome plate and burner stem screw washers. Replaced the burner knobs and the vent fan worked. The hardest thing was getting the holding washers back on as they are too small to go over the screw but open up as they go on. I did not have the right tool for this so used a hammer and a socket with an opening that would fit on the washer so I could bang it down.
