Even though the you might have a new dryer the vent line could be blocked with lint,or there are other parts that could go on a gas dryer,bad thermal fuse,gas coils,ignitor,sensor one of the thermostats,the only way to tell is to get in there with a meter,unplug the dryer remove at least one of the wires on the part you're checking and check the parts for continuity.that's a neptune those are the machines that put maytag out of bussiness a few years ago,i don't think it's new.you can go here and look up the parts i told you to check,if you need anymore help let me know.
