whirlpool dryer just stopped heating

[KRO]

I just replaced a thermofuse and got my dryer back working again but after a few loads now its stopped heating…I’ve checked the breakers and the lint screen and vent but where else can I check? How do I know if its the heating element or not? Would the timer have anything to do with it? I’m asking this because I just put a new one in before the thermfuse was replaced…my old one is still good…thanks:(
