re: Whirlpool dryer fuses keep blowing - Update in OP

call a chimney sweep or a vent cleaner to clean your vent all the way out to the exit. Nothing else will cause the thermal to thrip except restrictions and to much heat.

Neither of what you posted are the actual thermal fuses.

The thermal fuse is the white thing with the two blue wires.

You posted the hi-limit cut off and the hi limit cycling thermostat.

Those too can fail due to lack of air flow. A lot of times when those fail it's crap in the dryer itself between the fan and then vent screen.


Do the dollar bill test.

Open your dryer door.
Hold the door switch/button
Start dryer on no heat cycle.
Place dollar bill (or any paper) on vent (not the part the heat enters)
If it sucks to the vent, you have airflow, if not you have an airflow restriction and that is causing your fuse failure.

Also, did you change all the fuses when the first one broke?
You can buy all three for around $20, so it's best to change them. In fact that looks like the electric dryer cut-off for the Whirlpool alpha platform, so it's electric then that definitely comes in a pack with both fuses. (gas uses different temps, different parts)

It's possible it could have just been normal component failure. Those are the most likely to fail components on a dryer. They are pretty much sacrificial components, their failure prohibits other problems.
