Checked vent (good flow); replaced control inlet and drum outlet thermostats; temperature at filter inlet varies from 120 to 180 degrees; heaters both 19.5 ohms. Also substituted heat selector, timer and EOC signal board from a known to work dryer. This machine doesn't have a separate 4500 ohm resistor to drop the voltage for the timer. It appears to be part of the EOC board and reads 4500 ohms. Also, on the schematic there appears something called a top rod and a bottom rod. Does the Auto on this machine operate differently than the traditional method of getting timer motor current from the heating coils? Perhaps the top rod and bottom rod comprise some sort of moisture sensor?
