No heat at all.

Hello Friend, Your problem is very simple to fix. You need a thermal fuse and or heater element, both very simple and affordable to replace. Try replacing the thermal fuse first to see if that's the problem. To replace the thermal fuse just remove back cover of dryer and look down where the air blows out. Now, just to the left where all the wires are you will see a white plastic part with two wires plugged into it. This part is called a thermal fuse. Just remove these wires and replace the thermal fuse. If this don't solve your problem you will need to replace the heater element. To replace the heater element, with the back cover off of your dryer just look down and to the right of were the air blows out. You will see the electric heating unit with two fat red wires plugged into it. Unplug these wires and you will see on the sheetmetal housing two screws that hold it on, one on each side. On older elctric dryers there is only one screw that holds element in place, it is on the bottom center of element screwed in from behind. Remove screw(s) and remove old heater element. Now, lay the new element next to the old one and take notice that there is a heat sensor attached to the old element where one of the red wires unplugged from. Gently remove this sensor and install it onto the new element in the same location as the old one. If you have an older electric dryer, the old heater element doesn't have the heat sensor on it, just skip this step. Now, plug in your two red wires and re-install your heater element. Your dryer will run like new. Happy to help, Tim.

Check the following to address this issue.

Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced. A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective. Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.
