I've tested the heat coil and that has continuity. I've tested all the thermostats but one. the ones I tested all show continuity (0 ohms resistance) The one I didn't test has 4 leads so I wasn't sure how to test it. there are a red and blue wire each going to one pin of the thermostat and an orange / black wire going to another pin then jumping over to the 4th pin. The schematic says that this is the control thermostat. Interesting thing...when I disconnected the leads going to the heater element and started up the dryer, each lead showed 120 volts (+/-) - using the voltmeter and testing each lead to ground. Really can't afford a new dryer so I would really like to fix this one. Thanks in advance.

The one I didn't test has 4 leads so I wasn't sure how to test it. test for continuity across the (2) big terminals (Red and Orange/Black) 417.49012890 Wiring DIagram If there's 120v to chassis (ground) from each side of the (removed) Heater Element, then there should be 240v across those connections

Many Thanks - That looks like it might be the culprit. There was no continuity between the red and the large orange/black connectors. The same for the blue and the small orange/black connectors - no continuity. When I briefly connected the red and the orange/black wires and fired it up, the coils started generating heat. Since I have the beast all torn apart, are there any other parts you'd recommend replacing (as preventative maintenance) at the same time - since I'll be ordering a new control thermostat?

that should do it.. (the smaller terminals won't have continuity, but should have some high resistance) 4-wire Control Thermostat 134048800 click on picture

the 2 smaller wires are a bias heater, they are connected to a small heater within the thermostat, when gentle cycle is selected those 2 wires supply voltage to a heater within the thermostat to heat it so the thermostat trips sooner just so you know what they do incase you have to fix this puppy at a later date, but it sounds like you whipped her this time
