Description
Replacement Heater & Thermistor for Elegoo Neptune 4 Plus & Max
This 24V 80W ceramic heater and NTC 100K thermistor kit is a direct replacement for the heating and temperature sensing components in the Elegoo Neptune 4 Plus and Neptune 4 Max hotend. The 80W heater delivers rapid heat-up and stable temperature control up to 300°C, with integrated terminal connectors for quick plug-and-play installation.
If your Neptune 4 Plus or Max is showing temperature errors, slow heat-up, fluctuating nozzle readings, or thermistor faults, this kit restores reliable thermal performance in minutes.
When to Replace
Temperature error codes on the printer screen, nozzle temperature fluctuating during printing, slow or inconsistent heat-up, thermistor readings showing abnormal values, and the printer halting due to thermal safety faults.
Compatibility
This kit fits the Elegoo Neptune 4 Plus and Neptune 4 Max. It is not compatible with the Neptune 4 or Neptune 4 Pro — those models use a different heater configuration. See our separate listing for the Neptune 4 / Neptune 4 Pro heater kit.
Installation
Power off the printer and allow the hotend to cool completely. Disconnect the old heater/thermistor via the terminal connectors, remove from the hotend, install the new kit, and reconnect. No soldering required. Run a PID auto-tune after installation for optimal temperature stability.
