If only there is more information on what causes the fuse to keep blowing than I would have had this problem fixed a long time ago. Instead I searched and searched and finally decided to test the timer which appeared to be working. Not the case though, it was bad. I finally traced tge wires from the fuse holder to the door switch and timer. Looked up on how to test the timer and door switch. Turned out the timer was bad but nothing I had found lead me to believe that timer was the cause of the fuse blowing.
