Product review (5 stars): Just a fuse ... recommend replacing all heat regulation devices/sensors (kit).
DRYER
Whirlpool Duet GEW9250P(color code)

PROBLEM
Pushing the dryer "On" button brought up the indicator lights, but pushing "Start" button wouldn't start the dryer.

IMPORTANT NOTE
Replacing just this part, the Thermal  Fuse, is likely a temporary fix, as there is some other issue causing the dryer to overheat (and tripping the fuse), possibilities include:  clogged/dirty dryer vent run; sticking thermostat; failing thermister, etc.  I would recommend replacing ALL the heat regulation sensors/devices, which are available as a kit for less than $25, and then cleaning your dryer vent:

3392519  Thermal Fuse
3976615  Thermister
3391914  Thermostat 295 F
8318314  Thermal Cut-Off

I learned the hard way, initially just replacing the Thermal Fuse and Thermister, after which the dryer functioned; then cleaned the dryer vent run thoroughly (but there wasn't really a lot of debris, probably because this is something we do each year anyway) and verified good air flow.  Dryer ran normally for about a month, then failed again.  I happened to be present when the dryer failed and it was extremely hot, almost to the point of melting some clothing made of synthetics.

FIX
Unplugged the dryer and replaced all 4 parts above; access via removal of just the bottom front panel of dryer and the blower motor cover.

TOOLS
1/4" Drive SAE socket set (1/4" socket, specifically), flashlight, and needle nose pliers (helpful disengaging wire connectors)

Dryer running great now, and hopefully it will keep running!
