Product review (5 stars): Works Great, No Issues, But Doesn't Fit Photo
This works just fine and looks very similar to the image, but not exactly. It installed just fine and works without an issue.  However, the original switch was straight. This replacement has a bend in the design. This must have been a product improvement and I have had no issues with the switch.

This can be disconcerting when the supplier is advertising and calling it Exact Replacement.

To replace this switch, there are plenty of videos online to show you how to do this. It's a simple matter of unplugging the dryer, popping the top of the dryer off with a putty knife, removing two Phillips screws, unclipping the old connector and adding the new switch.
