Clare, first you have to make sure that your air vents are all clean and not obstructed. Then check your fuses. There should be two fuses for the dryer in your fuse panel if you are in north America and running on 110V. If those are okay it can get a bit tricky. This dryer model has a blower assembly that is belt driven. Check this video to show you how to replace that. Part number 29 in the diagram, and it is available at places like this . If the belt should be good, or a new belt does not fix it, you may have issues with the heating coil as well as problems with the thermostat and cut-off temp sensor. Let us know how well you are with a multimeter when you get there. Hope this helps, good luck.
