Not Heating / Temperature Problems
Heating failures fall into two categories: the appliance doesn't heat at all, or it heats but not to the right temperature. No heat usually means a failed heating element, blown thermal fuse, or broken thermostat. Wrong temperature typically points to a calibration issue or a failing temperature sensor. Both are usually fixable.
