My dryer does not get hot was fine last time used
Check continuity for the thermal fuse, hi limit thermostat, cycling thermostat. If they check out, check the heating element for continuity, resistance and make sure it is not grounded.
If these check out, look at the wiring diagram, see link, and you will see what else to check out.
