I purchased a timer plastic shaft we4m357. I don't remember where to place the wires. The letters on the timer are c, b, a, x, t, f. The wires are black, white, b&w, violet and one of them are hook together (2) either black or brown hard to tell. The paper work with the dryer shows all the parts but doesn't indicate this info as far as I can tell.
The wiring for the timer is as follows: The A terminal will have the purple wire which goes to the selector switch. The B terminal will have a black wire which is the L1 in. The F terminal would be white which goes to the gas coils. The S would be a black wire from the End of Cycle signal. X would be the Yellow black or Black and white to the motor switch. C would have what looks to be a double brown which goes to the start switch and motor.
