I do not have a volt meter. This laundry set up is about five years old and has been reliable. The reset button is like a rubber grommet on the back of the machine - I assume that it is for overheat protection although it did not pop out on this occasion (it did earlier in the day). There are two 15amp fuses that are solid and graphite in color(not glass) - Where can i find these? All ducting in and out of the dryer have been cleaned. This was a heavy laundry day so i'm hoping it is the fuses - How long do they usually last?
