Marta,
The fuse is in a fuse holder which is in an attached metal box on the right hand top back area. There are two. The fuses can be removed from the right hand back side. A short stubby screwdriver or possibly a dime is required to screw the cap of the fuse holder off. The fuse may be 'burnt' into the holder. Asco apparently has been recommending bypassing the fuse as this is a common problem - american wiring circuit breakers supposedly provide adequate protection. I have had three fuses burn out and it is now bypassed.
There is also a reset switch (button) on the back center which may just need to be pushed in and the fuses may be OK. My fuse always blew and the reset on the back never tripped.
