Dryer would not start.

On line advice said 40% of the time the problem was a one- time use thermal fuse. Next choice was a door switch assembly. Both parts were inexpensive so I ordered 1 of each. I tried the fuse first. It wasn't clear from the diagram exactly how to get to the fuse. I removed the back panel using a rechargeable nut driver and saw what looked like it could be the fuse. It was held on the same size hex screws as the back panel. I removed the screw and saw it was the fuse. I removed the wires with needlenosed pliers. I replaced the fuse and tested the machine. It worked fine. I'll still replace the door switch but it was the fuse that caused the initial problem. I appreciate the online service, I feel like it saved me considerable time and money.
