My maytag dryer is not heating properly. It is not a vent problem. It heats but not very hot and takes clothers forever to dry. The thermal fuse kit L248 looks dark and worn but I thought if that was the problem the dryer wouldn't come on. Is that correct ? What else can I check? I hate to spend money on different parts and that not be the problem.

That's exactly what happened to mine and replaced it and worked great, try it the part is not that much.
