What is the most common problem with a GE dryer?

What is the most common problem with a GE dryer is not heating or not drying clothes completely, followed by not starting at all. For GE electric dryers like GTD42EASJWW and GTD65EBMRWS, top failure is thermal fuse blown due to overheating from clogged lint filter or blocked vent hose, causing dryer to not start or no heat, fuse costs 10 to 25 dollars and is safety device on blower housing that cuts power to prevent fire, 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, costing 30 to 80 dollars for part and causing dryer to run but not heat, clothes still wet after cycle. For GE gas dryers like GTD65GBMRWS, most common is gas valve coils or igniter failure causing dryer to not heat. Third is dryer not starting at all due to blown thermal fuse or door switch failure at 15 to 30 dollars. Fourth is drum not turning but motor running, due to broken belt at 15 to 30 dollars that snaps after 6 to 9 years. Fifth is loud squealing or grinding noise during operation due to worn drum rollers or idler pulley at 20 to 50 dollars. To prevent most GE dryer problems, clean lint screen after each load, clean vent hose and outside cap yearly, do not overload beyond 3/4 full, and avoid excessive dryer sheets.
