Product review (5 stars): This kit was exactly what I needed, it was ...
This kit was exactly what I needed, it was priced far lower than elsewhere, and it was delivered on time.  The kit contained the thermal fuse as well as high-limit thermostats for both gas and electric dryers.  The instruction sheet included in the kit explains which piece is which and why the high-limit thermostat needed to be replaced at the same time as the thermal fuse.
