I watched several YouTube videos to find out how to test electrical components for the dryer, then I watched the videos associated with the parts that were needed from Appliance Parts Pros.com. This is a great web site because they listed the parts associated with the dryer, showed a video for how to install each part, then checked for the compatibility of each part for my specific dryer. I ordered the parts, then happily received them in two days! Running the diagnostics for the parts and disassembling the cabinet was the most challenging part of the repair. Once the parts were received and installed, reassembling the cabinet was easier. A couple of thoughts here: one, I was impressed with the quality of my old dryer (manufactured in the late 1970's or early 1980's); and, two; how impressed I was with Appliance Parts Pros because they stocked the parts and had an incredibly integrated method to identify the correct parts and ship them in two days! My wife thinks that I'm a genius, but it was really attributed to the help and ease of Appliance Parts Pros and YouTube.
