Heater over-temperature

E63 is a fire safety condition. Do not use the dryer until resolved.
A safety limit has caught the heater running too hot, and the overwhelming first cause is trapped heat from poor airflow, so clear the screen and the whole vent run before suspecting a part
With the airway open, test the cycling thermostat that is supposed to click the heat off and on: stuck closed it never lets go, and the box climbs until the limit trips
Look inside the heater can for an element coil that has sagged and is touching the sheet-metal shell, which dumps heat straight into the frame and spikes the temperature
Confirm the high-limit itself still reads closed cold and opens above its rating, since a lazy limit both causes the trip and fails to protect on the next runaway
Pro Diagnostic Tip
If E63 keeps coming back even after you have cleaned the vent, the repeated overheats have usually cooked the cycling thermostat until it no longer modulates, so it now lets the box run hot on its own. Renew both thermostats together as a set — leaving the tired one in invites an immediate repeat.
