Product review (5 stars): These Fuses Are Always Needed For Overheating Of Your Dryer
I have a Whirlpool Senseon Dryer which I love. It senses when the clothes are dry and automatically shuts down, saving energy. While I clean my lint screen after every load, little did I know that there is a good size lint holder in the bottom of the dryer. I found this out, when my dryer wouldn't start.

These Dryer Thermal Fuses blow out when the dryer overheats, keeping more expensive parts from being burned out. Having that lint holder full, made my dryer overheat, but luckily the thermal fuse blew preventing any damage. I've also had the fuse blow when I use the dryer too much, making the dryer very hot, overheating and blowing the fuse.

It's a great idea to keep at least a couple of these fuses around, as you never know when your dryer will overheat. Also, you just never know how long these fuses will last, as I've had duds that lasted less than a year and other fuses lasted over 3 years. The prices are better when you can get them cheaper buying them in pairs like on this 2 pack deal.  Just make sure the Whirlpool name brand is on the description, like here. I accidentally bought a generic one and it didn't last 2 months.
