Product review (4 stars): Works but needs a little engineering for some models.
This kit worked well, but there are no instructions, and I had to do a little engineering to get it to work on our dryer.  I replaced both parts, because if the fuse is blown, its probably because the other part is 'bad'. Replacing just the fuse might cause it to re-blow in a short time.  One problem is that the original part had different size connectors, so you have to use all the parts in the kit, which causes one of the exposed connectors to come dangerously close to the metal chassis.  I had to bend the connector out of the way, and I didn't think using electrical tape would be safe, since its right next to the heater coil (didn't want it melting/smoking the tape).  Also, the original part did not use the screws to hold the part in place, but this needed screws. I used two unimportant screws off the back panel to do this.
