Replaced dryer gas valve coil. This didn't solve the problem. Most videos showed opening the back panel, this was not the case for our dryer. Opened the front, removed top, took out the drum and vacuumed. So much lint, yikes. Took a while to find the part, not in locations as diagrams showed but finally found it. Replaced fuse, could have done it without removing the drum. Put everything back and Voila! Working. Saved ourselves repairman costs or new dryer. Now we know how a dryer works. Thanks.
