Heating element in my dryer not turning off

Device: Dryer

Two days ago after running a load in the dryer, my daughter tried putting in a new load, but the dryer wouldn’t start back up. The cabinet was also very hot to the touch. It got so hot that it blew the thermal fuse, likely preventing a fire.

Checking the device power-meter in the Sense app, I noticed the dryer’s heating element (about 5000 watts), had been on for about 45 minutes. From historical Sense data, the “normal” for this dryer it to turn the heating element on for about 1 minute, then off for about 1 minute. So 45 minutes of continual on-time was very uncharacteristic for the heating element to run.
