Works but won't heat

Hi. I have and older model Hotpoint electric dryer… It’s been a good one over the years but it gradually stoped putting out hot air…Still works fine…just no hot air…I’d like to be able to repair it if I could…Any help would be much appreciated… I was told it was probably either the "heating element" or the "thermal fuse"…I don’t know where either one is located…Is there an exploided diagram I could download to show me where there located?..Thanks again…:slight_smile: …Pete
