Troubleshooting guides for electric dryer repairs are found online at The Family Handyman and PartSelect. At both sites, problems are placed in categories based on issues, including the dryer's inability to start and a lack of heat.
At The Family Handyman, a possible cause is identified for each problem. For instance, if the dryer is not heating properly, a part such as the thermal fuse or radiant sensor is probably broken. Each potential problem has a step-by-step slide show displaying how to perform the repair.
PartSelect shows a list of common dryer troubles. Clicking on the title connects to another page with solution ideas. For each problem, a repair video is available, as are links to replacement parts.
