Question about Dryers
In most dryers there are two thermal fuses and two thermostats. If the vent hose was restricted it is most likely that the thermal fuse on the heater assembly has failed . The fuse and thermostat come as a set in that in most cases the thermal fuse blows as a result of the thermostat failing.
The second set of a thermal fuse and thermostat is located on the air exiting the drum closest to the vent and control the drum air temperature. A qualified repair person can easily with power disconnected check these for devices and the one that is open at room temperature needs to be replaced.
Hope this helps?
Components in blue box are the thermal cutoff fuses
Parts below are used in the heater assembly to control the heater maximum temperature. If the thermal cutoff fails the thermostat is also replaced. These parts come as a set.

You may have a bad timer: Also, there may be a separate thermal fuse for the motor, usually an inch long white plastic one attached to the blower housing.

there are several issues that can cause this most common is the vent restricted backing up heat in the dryer if its as old as you say you need to check the whole vent system it has to be 4inches dia all the way if its mashed or drooping under the house its restricted if its folded over or mashed behind the dryer its restricted the thermal limiter is a safety thermostat it opens about 300 degrees to prevent fire the dryer has three thermostats an operating thermostat a safety thermostat and the thermal limiter if the operating thermostat fails then the safety thermostat takes over and cycles on about 165 on and off if both thermostats fail then the thermal limiter opens about 220-300 depending and it doesn't reset and cuts all the power to the dryer till a tech can check everything i just told you about so if your vent is clear and the best way to vent is 4inch pvc drain pipe 90 it up behind the drier then connect with a short peice of metel vent then just replace all three thermostats

I had the same problem last month. My heater element broke in two places. This created an electrical open that prevented the heater from functioning. I replaced the heater element and my problem was solved.
In order to check your heater element: With the machine unplugged, disconnect one wire to the heater element and then use an ohm meter or multimeter across the heater element lugs to read resistance. Infinite ohms = open circuit.
