Bosch dryers can be a bear to work on, without the proper tools and knowledge this dryer may get the best of you. After many years in the appliance repair field I have become one with this dryer, I have replaced just about every thinkable part on this dryer. A dryer has to be one of the simplest appliances to work on, a dryer is made up of several components, a motor, a drum and a belt, they are pretty simple appliances to learn to repair yourself.
Bosch dryers can be tough to diagnose, often the noise complaint that are associated with them is what is difficult to narrow down, a no heat issue can be simple or easy to figure out, most times the thermal needs to be reset.
This fuse is located on the dryers heater canister, the canister is accessed from the rear of the dryer, there are a bunch of T-20 screws that hold the back panel on. using a drill will speed up the process of this repair, once the dryers back panel is off you will see the heater canister located on the back right of the appliance.
On the heater assembly there is a small circular thermostat with a little red button in the center, if you depress this button and hear a click you found the problem. Often times this thermostat will trip due to a venting issue, if you noticed that your appliance is taking longer than normal to dry before the fuse tripped the vent may need to be cleaned.
Also note that a kinked hose behind the dryer can cause this same issue, lack of hot air being exhausted will create hotter than normal temperature tripping the fuse on the heater canister.
