My hotpoint TCN65A tumble dryer doesn't heat up?

Hello again, more assistance is required please Regarding my TCM65A, i have replaced the heating element as only the 1 coil was heating up (to about half way along the 1 coil), the new element is no different, still only heating up only half way on 1 coil (there are 4 coils) is this correct? I assumed that all 4 coils should get hot? I then replaced the 2 thermostats, still no change.
Thanks

Thanks for that, the one with the green dot has reset itself by dropping it onto the floor, and only half, of one of the heating elements appears to be working. Hopefully save a visit by an engineer, much appreciated.
