Are you talking a fuse, or circuit breaker?

What I need to know is what is the fuse, is it a round screw in fuse, a buss type fuse, or a breaker that you can turn off and on?

ok. If you visually inspected the dryer and made sure the heating element coils are not touching, or close to touching any part of the dryer, indications point to the fuse panel. You can use simple ohms law to determin if the heater is ok. take a resistance reading of the heater and divide that by the voltage at the wall. This will tell you the amp draw the heater is pulling, it should be around 21-26 amps.

No. When I run into these problems, it is always the house wiring or fuse/breaker box.

Look for burnt wiring, blackened wire, corrosion, anything out of the ordinary, even a loose wire will cause this. I'm not to sure about a slo-blow fuse for it, usually those are buss type fuses. I run into microwaves that do this quite a bit on circuit breakers where the magnetic draw on the wire will trip the breaker, not beacause there is too much of an amp draw, simply because the magnetic energy pulled on that leg of the breaker will trip it. But in your case inspect the connection at the panel.
