The thermal fuse opens from sensing overheating in its area only-not overcurrrent. Make sure the spade terminals grip it tightly as any looseness will cause failure. If that is fine then replace the sensor that fits into the sump assembly as it is probably not sensing correctly and that will cause overheating of the unit as the water gets too hot and that heat is of course picked up by the fuse. I have never had a control at fault for this issue.
