Thanks that helps! I just wish they would tell me what the power should be going to the Sub pcb.
You should be getting 120 AC Voltage on CN1 (Brown & White Wires and/or Brown & Yellow Wires) of Main PCB which sends power to Sub PCB (see page 4 of Tech Sheet): You may need to press the power button to test/verify voltage on either set of wires.
Unplug dryer and verify Ohm's on Thermistor CN2 (Blue & Red Wires) of Main PCB: Must set Multimeter to 20k Ohm's and remove CN2 wire harness from Main PCB to verify ohm's.
Unplug dryer then remove wires from Door Switch to verify continuity/ohm's between COM & NO and COM & NC (if no continuity on either set of terminal pin's then press door switch to check again - see page 5 of Tech Sheet): Must set meter to lowest Ohm setting to test terminal pin's on Door Switch.
Also, see if your getting power to the Door Switch on either COM & NC or COM & NO (power shuts off when door is open on one set of wires).
Look for any burnt marks on both Boards (either near the connector or on the wire harness).
