We have replaced the thermal fuse on our dryer more times than I can count. We thought there was a clog underneath our house, so we vented the dryer inside for a while. I had covered the end of the hose with tights (all I had on hand). It would run and dry, but would take 3-4 hours to dry one load of towels and usually 2 hours for any other kinds of clothing. Today, I bought a cheap pair of pantyhose to put on the end of the vent, to see if that could speed up the drying time. After drying a small load of t-shirts for about 15 minutes, the thermal fuse blew again. So, obviously, the problem isn't the venting system under our house.

We have replaced the heating element and also thermostat in the past 4 months or so (in addition to multiple thermal fuses). Is there something we are missing? What else could be causing the thermal fuse to blow?

Well, when we replaced 3 parts back in December, I feel like we gave the inside a pretty good cleaning. I haven't checked the blower wheel though. The model number is TEDS74OPQ0. The dryer's about 10 years old and 4 months ago was the first time we've ever taken it apart and cleaned it like that. Now, it seems like since we replaced the parts, it's been nothing but trouble. I really have liked the washer/dryer that we have and I'm not too impressed with the new models out there, so I'm putting off getting a new one as long as possible, but there comes a time when it's not cost efficient to do so. I'm wondering if this can be fixed or just throw in the towel.
