Yeah, hi-limit was kicking off the heat circuit.
Yes, but as you can see the flames still managed to get outside of the containment can. The lint in that area had ignited, and burnt lint was found in other areas of that dryer. With proper venting and proper dryer placement in the home, you can reduce needed maintenance. Best case scenario, the laundry room would be built on an outside wall of the home, with the vent exiting said wall.
