Product review (4 stars): Thermal fuse kit is for both gas and electric dryers.
The only reason I did not give it five stars, is because the description is incomplete. The package (and picture) contains parts for BOTH an electric and gas dryer. We have a gas dryer, and I looked all over inside the dryer to no avail (prior to ordering) for the location of the third fuse,  part 53-0771 (the blue one) which is for an electric dryer.

Fortunately the instructions are clear.
