## Summary description

Replacement hotend thermistor compatible with Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers. The thermistor measures the nozzle temperature for hotend temperature control and printing reliability. Intended as a spare part for hotend assemblies to restore accurate temperature sensing and stable extrusion during FDM printing.

## Long description

Replacement hotend thermistor compatible with Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers. This component measures the nozzle temperature and provides feedback to the printer control board to maintain accurate hotend temperature for consistent filament melting and extrusion. Designed as a spare part for hotend assemblies, the thermistor helps restore reliable temperature sensing after wear or damage to the original sensor.
Advantages
The thermistor offers precise temperature measurement in the hotend area, enabling stable thermal control and consistent extrusion during FDM printing. Its compact design suits direct installation in standard hotend cartridges and heater blocks used on the specified Elegoo models. As a dedicated replacement part, it reduces downtime by allowing quick restoration of temperature feedback without replacing larger assemblies.
Suitable for
Repairing or replacing a faulty nozzle temperature sensor on Elegoo Neptune 4 Plus
Repairing or replacing a faulty nozzle temperature sensor on Elegoo Neptune 4 Max
Maintaining accurate temperature control for PLA, ABS and other common filaments
Use in service kits for hotend maintenance and troubleshooting
Key specifications
Function: measures hotend/nozzle temperature for printer control
Compatibility: designed for Elegoo Neptune 4 Plus and Neptune 4 Max hotend assemblies
Form factor: compact thermistor element with leads suitable for hotend cartridge installation
Operating role: temperature feedback sensor for FDM extrusion control
Material characteristics: temperature-sensitive semiconductor element and insulated leads designed for thermal environments in hotends
How to use
Power off the printer and allow the hotend to cool before beginning replacement. Access the hotend assembly according to the Neptune 4 Plus / Neptune 4 Max service instructions, remove the existing sensor from the heater block or cartridge, and install the replacement thermistor in the same position. Secure leads and connectors to the control board using the original connectors or compatible terminals, then perform a temperature calibration or PID tuning if required by the firmware to ensure accurate readings.
Usage recommendations
Handle the thermistor element and leads carefully to avoid kinks or damage to insulation. Verify wiring polarity and secure mechanical fixation in the heater block to maintain good thermal contact. After installation, monitor reported nozzle temperature during initial heating and run a test print to confirm stable extrusion and correct temperature control.
