The small element blew out consequently shorting out the infinite switch.

The very first thing we did was turned the circuit breaker off and unplugged the range.
My husband removed the back panel and unplugged the switch. Drew a diaghram of the color coded wires. When we received the new one he broke the extension bar off to fit the knob, plugged it in and we were back in business. It was very easy for my husband as he is a mechanic (millwright). However, if you are mechanically inclined it is an easy fix.
