The dryer runs when activated, the element starts to heat up and then shuts off after a while due to overheating. There is no flow of air exhausting from the dryer and there is very little hot air inside the drum itself. I have checked the filter,.the filter tube to the drum and its not plugged up, the air vent to the outside is not plugged up either. So what gives if all the tubes inside are clear why does the air not circulate in the dryer and exist through the exhaust tube?? The drum turns and the belts are tight. Trying to fix this for a friend. Any suggestions would be appreciated. PPB
No air flow correlates to the Blower not turning on..With power disabled, can you gain access to the blower and make sure it doesn't have anything inside it that would keep it from rotating to move air? If the blower is able to spin freely, then I would reapply power to see if the blower is getting AC to it ( Use extreme caution while working inside the dryer when you have AC applied to it) You may have a defective blower/motor assembly.

DRYER OVERHEATING: Heating Element
A defective heating element can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.
Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.
Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.
Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.
Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

Bad motor windings
Either a motor with bad windings,. or an over heating problem?

a thermal limiter is a safety switch designed to keep a dryer from overheating, by either shutting off the heating element or the dryer itself if activated. They don't normally need replacing (unless you know your dryer overheated and activated it). If you have no heat in your dryer, chances are you have a bad heating element--the most common dryer problem
Overheating is most probably caused by low air flow past the heating element. High air flow would not allow the air to overheat. Check to be sure the fan is rotatingn freely and then check the heating element/wires for dirt or other obstructions. We were having "burning" problems that were revealed to be an errant latex glove that excaped from my wife's pants pocket during an earlier drying cycle. When it hit the elements, it began to cause a scortching smell and partially melted. In this instance, the air flow about the element was restricted and the reamining air overheated and the sensor sounded. When the sensor sounds, heating ceases and you will get non-uniform drying. I picked off the pieces of the glove from the wires and except for an unrelated drive belt breaking, we have not had problems.
Electric dryers usually have a motor with a switch that prevents the heating element from being powered until the motor is spinning. In series with this are limit switches to prevent overheating if there is too much lint or too little air flow around the heating element. Also, the motors are induction or brushless. So the smell is coming from the heating element burning off some lint nearby as it reaches the high limit temperature and shuts off. This can be due to two conditions if we can assume the motor is running (has a switch that is closing to power the heating element). The most likely condition is that the drive belt is off the pulley or broken and the drum is not turning. You will be able to tell this easily by sounds or by opening the door to see the drum slowing down. If that's not it, examine the blower which forces air through the drum. There are a lot of variations, so look for air intake and drum exhaust ports that can be clogged with a sock, lint, etc.
Probably restricted air flow caused by lint build up. Clean out dryer and all vent pipes, check damper outside and see if it opens. After you clean out everything run dryer on aif fluff/no heat cycle and see if there is good air flow outside. If it is electric it could be that the heating element is burned out and shorting out against the frame. This can cause overheating.
Is there power to the Dryer? If so then Dryer most likely shut off due to a air flow blockage. This could be a clogged Lint Filter, or a Clogged Air Duct Exhaust (the hose that goes from your Dryer to the outsideof your house). If there is no air flow over the Heating Element the Heating Element will OVERHEAT and the Thermal Safety Fuse will Open cutting off the power. Some Thermals will re-set after cooling down. Others have to be replaced.
