I have replaced the thermal fuse 3 times in a month. First time I replaced it, I replaced the vent hose also and cleaned the outside vent, plus the venting inside the dryer. The dryer still runs extra hot even when the setting is on low. I can turn on the air dry and it runs fine, but anytime I'm on a regular dry setting it runs extremely hot, which keeps blowing my thermal fuse. I've checked everything else I can think of and it all has checked out fine. I even decided to replace the t-stat just incase it was faulty and it still runs hot.....not sure what else to try...HELP
