Product review (5 stars): Direct replacement for my Whirlpool duet dryer
I bought this large pack because my Whirlpool duet dryer kept on blowing the fuse. My dryer vents through my roof and it turns out that a bird decided to build a nest in my vent and it blocked the dryer. This could have been very bad if it caused a fire and I'm glad I figured it out before it was too late. The first sign that I had a blocked vent was that my clothes would be very hot coming out of the dryer. They'd also take a long time to dry.

If you're having to replace these thermal fuses I'd recommend either calling a professional or checking to make sure it is vented properly.
