The air blows but there is no heat. damn thing is only year and half old and samsung will not help

If there is no heat when dryer comes on you need a new heating element.

Unplug the dryer. Remove the control panel on the top. Look inside for a sheet of paper with the wiring diagram or service instructions. If you don't find one there, look on the back cover panel. (Every US appliance maker provides this, but I've never looked inside a Samsung dryer so I don't know about their practice.)

If you find the wiring diagram, you can use it to identify the wires going to the thermostats and heating elements. Now you can use an ohmmeter to check which part is open; the wiring colors marked on the diagram will let you find the terminals in the control panel going to the thermostats and heaters so you don't have to take everything apart for diagnosis. Note: in a typical dryer, if you get no heat on Medium, but you get heat on the Low setting, you already know the Medium heat element is burned out. High heat uses both elements.

If you don't find a wiring diagram, you will have to look for the thermostats and heater terminals. Usually there is a thermostat mounted on the door frame at or near the top of the opening to the drum. There will be a second thermostat mounted on the top of the heater pan or box. Usually these are supposed to be closed (you get continuity) when they are closed. The heaters should show some resistance, but should not be open.

If you find an open circuit from the control panel, it doesn't mean the part itself is bad; it could be a problem with the wiring terminal connecting the part. This is often obvious when you see it; the insulation at the terminal will show signs of overheating.
