NTC Thermistor 100K 3950
The thermistor's glass bead is highly sensitive to mechanical stress. On the Ender 3 V2, the retention screw often compromises the insulation of the lead wires, causing an intermittent short-circuit that reports a sudden temperature drop to the firmware. When the firmware sees a drop while applying power to the heater, it triggers a 'Thermal Runaway' halt to prevent a potential fire.

24V 40W Ceramic Heater Cartridge
Internal fracture of the resistive heating coil within the ceramic core can cause inconsistent heating. If the heater cannot reach the target temperature within the firmware's 'WATCH_TEMP_PERIOD', the safety algorithm terminates the process to prevent a situation where the heater is on but the sensor is not recording a rise.

Hotend Assembly (Complete)
A full hotend assembly is recommended if the mounting threads for the thermistor screw are stripped or if the heater block is heavily encrusted with leaked filament (plastic creep), which can insulate the thermistor from the actual heat source and cause thermal lag.
