SOURCE: Hotpoint NVL333EY Electric dryer blows thermal fuse
I had the same thing happen, I replaced the thermal cutoff and made sure no lint build up. It lasted a week then blew again. I then replaced it again and got to thinking why it would blow. I then took apart the exaust inside the dryer running fron the drum to the motor and right before the motor was a build up of lint ane particals that was almost like compressed sawdust which was blocking half of the line. I cleaned this out and it seemed to work much better.

Based on the information that you provided, if you open the door in mid-cycle and the motor shuts off, but the element stays on, this will stop the air flow through the dryer and the element. The element temperature will rise drastically because it is not being cooled. Subsequently, to prevent a fire, the thermal fuse will open, shutting the element, and in some cases the motor, down.
A heating element gets its power from the timer, through the cycling thermostat(s),and to 1 side of the element.
When the motor starts, power is passed through the centrifugal switch in the motor, through the hi-limit thermostat and the thermal fuse to the other side of the element.
There is no ground wiring involved in the heat side of the dryer.
1. An element can stay on because it has broken and fell against the metal tube where it picks up a ground. Solution is to replace the element.
2. The centrifugal switch mounted on or in the motor can fail to open when the motor stops and allow current to flow through it
until the points in the timer open up, breaking the circuit.

SOURCE: thermal fuse keeps blowing
they will blow if the heat dont get out of the dryer and builds up inside / check and see if vent hose behind dryer is kinked or vent going outside is open / it will be one of those two.
SOURCE: keep blowing fuses
hi, make sure you are using a time delay fuse and not a regular fuse. this may be the reason why the fuse keeps blowing out on your dryer.
SOURCE: Have replaced heat element, thermostat, thermal
I'd like you to try something easy. Set the dryer to Air Fluff and see if the dryer still puts
out Heat let it run for about 2 full minutes If you dryer is still putting out Heat get back to me

I can understand how important it is to have your dryer working properly. However, without the model number, I can only provide some general information on the issue. There are several components that can cause a dryer to stop heating. These depend on the source of power that the dryer uses. If the dryer is electric the problem could be caused by a failed thermal fuse, hi limit thermostat, control thermostat, thermal cut-off, or heating element. This could also be cause by a blown household breaker (there are two for this type of dryer, and one can blow or pop without the other one), or a failed timer. Some of these will also cause a gas dryer to stop heating, such as the thermostats, the thermal fuse and the thermal cut-off depending on your model. However, there is also the ignitor, the burner, the safety valve, or the coils that can cause it as well. In order to determine which part is causing the problem you will need to test the different components. If you could reply with your model number and any additional details about this, I can then provide a more detailed answer.
