My electric dryer is blowing the fuse after running only 2-3 minutes. The clothes are getting warm - so the heating element seems to be working. After the fuse blows I can reset it right away - The switch won't snap back into place until a few minutes have passed. Vent is not clogged - I checked. Today to test things further I ran the dryer on "air" dry & it worked fine - no blown fuses - ran about 15-20 minutes without a problem. What do you think - dryer problem or fuse box issue?
