Bypassing safety devices like fuses and overheat thermostats is about the dumbest thing you could do to your appliance. Those devices are there for safety. If something were to go wrong, those devices will save your life!
This is another dryer with a grounded out heating element. It got hot enough to blow the high temp safety thermostat. Somebody (not sure who) decided to just bypass the thermostat and keep using the dryer. They are lucky they did not have a house fire with this one!
