What is the most common problem with a GE electric dryer?

What is the most common problem with a GE electric dryer is not heating or taking too long to dry clothes, often due to thermal fuse blown or heating element burned out. For GE electric dryers like GTD42EASJWW, GTD42GASJWW, GTD65EBMRWS, and GFD65ESSNWW front-load, top failure is thermal fuse blown due to overheating from clogged lint filter that was not cleaned after each load or blocked vent hose behind dryer and outside vent cap clogged with lint, thermal fuse is safety device on blower housing that cuts power to heating element to prevent fire, costing 10 to 25 dollars, and causes dryer to run but not heat or not start at all, accounting for about 25 percent of service calls. Second most common is heating element burned out after 5 to 8 years due to lint buildup causing overheating, heating element coil breaks and shows no continuity on multimeter, costing 30 to 80 dollars for part plus labor at 150 to 300 dollars total, causing dryer to tumble with no heat and clothes still wet after cycle. Third is high-limit thermostat failed at 15 to 30 dollars that also cuts heat if overheating. Fourth is broken belt at 15 to 30 dollars causing drum not turning. Fifth is door switch failure at 15 to 30 dollars causing not starting. To prevent most GE electric dryer problems, clean lint screen after each load, clean vent hose yearly, and do not overload beyond 3/4 full.
