Maytag Centennial Dryer, Model # MEDC400VW0, firstly replaced just the thermal fuse (part#3392519) and cleared all venting, fuse blew again. Secondly, replaced Internal bias operating thermostat(Part#3387134), High-limit thermostat(3977767) and used Thermal cut-off fuse kit(3977393) and again thermal fuse (3392519). Dryer ran about 15 minutes and fuse blew again. Other information for diagnosis, dryer runs same heat in all cycles including fluff or no heat cycle. At a loss as to what is causing the heat to run constant, causing the overheat and fuse to blow.

Thank you Denman, the coil was touching the case as one of the ceramic holders had broken. In the past I have had broken heater coils, but they just stopped producing heat. This was the opposite, it was producing too much heat.
