Our Whirlpool Cabrio dryer stopped working and we had a Sears tech look at it. He plugged in his little computer and determined the thermal fuse had blown. He replaced it and the dryer worked for 2 days and did the same thing. We put in another thermal fuse, the dryer worked for 3 loads, then stopped again. What is the root of the problem??? Can I fix it? The Sears work is under warranty (we won't tell them we put in another fuse ;) ) but the techs suck and won't come out again until mid-December.
