Samsung dryer no power

Many dryers have something called a "thermal fuse" which shuts off the power if the unit overheats. Check your dryer manual or seach online to find out where it is located. You can buy these at most appliance repair shops. They are usually easy to change. Just unplug the dryer before working on it. Also you should remove and vacuum out your dryer vent hose. If it is clogged with lint from years of use that could cause the dryer to overheat and blow the thermal fuse.
