When the vent does not exhaust air properly, your dryer will feel very hot to the touch at the end of a normal cycle..
Similarly, you may ask, how hot do dryer vents get?
The exhaust temperature of a dryer typically cycles from 50 to 71°C (120 to 160°F), though there is a potential if the dryer is broken it could be higher (any dryer made since the 1980's has a thermal fuse in it, hard to find info but it sounds like these often blow at 198 or 185°F).
Additionally, what does it mean when your dryer gets really hot? It could be due to a blocked vent. A restriction in the exhaust vent reduces air flow. The rising temperature inside the dryer will make the top of the dryer feel hot and it will also usually trip the high limit thermostat.
Similarly one may ask, how do I know if my dryer is too hot?
When this happens, the dryer gets too hot. To determine if the heating element is at fault, use a multimeter to test each terminal for continuity to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.
