## Long description

Thermistor Creality SERMOON D3 3103020149 – temperature sensor for 3D printer hotend is a replacement thermistor designed to measure the temperature of the hotend and provide feedback to the printer controller. It is intended for use in compatible Creality SERMOON D3 models and other printers that accept the same thermistor type. The component helps maintain accurate temperature readings to support consistent filament extrusion and stable print quality during operation.
Advantages
The thermistor offers accurate temperature measurement for the hotend, enabling the printer firmware to perform precise temperature control. Its compact form factor is suitable for integration into the hotend assembly without significant modifications. As a direct-replacement part, it supports routine maintenance and repair workflows, helping to restore proper temperature sensing when the original sensor is damaged or degraded. The part is compatible with common wiring and mounting methods used in Creality SERMOON D3 hotends.
Suitable for
Repairing or replacing a faulty hotend temperature sensor on compatible Creality SERMOON D3 printers
Routine maintenance to restore accurate temperature feedback in the hotend
Use in other 3D printers that accept the same thermistor type and wiring
Testing and calibration of hotend temperature control systems during setup
Key specifications
Function: hotend temperature sensing
Sensor type: thermistor (negative temperature coefficient)
Form factor: compact cartridge-style sensor suitable for hotend insertion or mounting
Connection: insulated lead wires compatible with standard hotend wiring harnesses
Operating role: provides resistance change with temperature for controller measurement
How to use
Power off the printer and allow the hotend to cool before replacing the thermistor. Remove the hotend cover or heater block access according to the printer service manual, disconnect the old thermistor leads from the controller or connector, and gently extract the sensor from its mounting point. Insert the replacement thermistor into the same position and secure any retaining hardware or insulation. Reconnect the sensor leads to the controller, verifying proper polarity if applicable, then power on the printer and confirm temperature readings in the firmware or control software. Perform a temperature test and, if needed, update firmware configuration or PID settings to match the new sensor characteristics.
Usage recommendations
Use only when the printer is powered off and the hotend is cool to avoid burns or damage. Verify compatibility with the printer firmware and wiring before installation. After replacement, monitor the hotend temperature during the first heat-up and adjust firmware settings if temperature readings differ from expected values.
