Working on Maytag centennial electric dryer for a friend with little money. No light inside of dryer but the bulb is good. I opened the back and tested the thermal fuse, element, thermostats and all have continuity with no wires attached to them. I tested the door switch and the start switch and both have continuity when in use. Power is coming into the timer although I don't remember which colors I had checked to see 240 volt. I bypass blue wire on timer and the white wire on the starter switch with the red stripe and plugged into 120 volt and ran the drum and motor for a while so I then changed out the timer but only to get the same result. The wiring connections on all the ends look to be in good shape. I hope to go back today and continue working. I don't know if I have received a new defective timer, or perhaps I should post the wiring diagram for this dryer on this site in order to get help. Thanks
