Diagnosed the problem on appliancepartspros website. Watched the video. Opened the back and tested the fuse and thermostat with my multimeter. Ordered the parts and would of received the next day except for FedEx forgot to put them on the truck. Replaced the two parts and and put the back,back on the dryer. Now have heated air! All in total including removing the back and testing and then replacing the parts and reinstalling the back I would cay was less then 30 minutes.
