I tried taking the signal control knob off and using it for a timer knob and it worked for a short time but the settings were in the wrong cycle. Then it stopped working. I looked up the part I thought I needed and ordered it. However, I did not have the correct name of part I (though it was called Control) so I ordered the wrong part. I realized my error but was still unsure. I called the customer service/support line and a very nice person looked up the name and correct part number for me and it was shipped out the next day, I received it quickly, I slipped it on, it fit perfectly and my dryer is now working again. Wish I had called sooner and requested help. It also would have been helpful if the picture of the knob on the website had detail so I would have known the name of the part I was looking for.
