Ordered new part. Unplugged dryer from the outlet. Removed small metal cover on upper back of dryer. Matched old and new part to determine if I had the right part. It matched. Removed the knob on front panel. Removed the old part by lifting a small tab on one side of the part with a screw drive.. Twisted to remove. Left wires hooked up. Put new part in place. Changed wires one at a time to be sure they went on the correct position on the new part. Replaced back cover. Replaced knob on front. It worked. Yeah !!!
