Thermal fuse blown repeatedly

Samsung dryer. Blowing cold air. Tested to learn thermal fuse (DC47-00016A) blown. Replaced and reassembled. Worked great for 5 minutes, now blowing cold air again. Thoughts? Do I just replace entire heater duct assembly? Is there a short somewhere? I don’t even know how to diagnose that…

Any assistance would be greatly appreciated!
