Product review (4 stars): 107 or 109?
Ordered Part# 3406109 and received #3406107. This works perfectly. The picture shows 3 wires and my drier has only 2. However the connectors are 3 wire on the drier, so center wire doesn't go to anything. Easy to swap out if you know how to lift top of drier.
See video: http://www.youtube.com/watch?v=95sXlRjCsXw You could let customers know these Part numbers are interchangeable and that 2 wire system works with this 3 wire switch. Would give you 5 stars, but you had me scratching my head, because I am an amateur at this.
