## Long description

Replacement thermistor for the Prusa MK3 and MK3S hotend provides accurate temperature sensing for the nozzle assembly. Designed to function as a direct spare or repair component, this thermistor restores reliable thermal feedback to the printer’s control system, ensuring consistent extrusion and temperature regulation during printing operations.
Advantages
The thermistor offers precise and stable temperature measurement tailored for Prusa MK3/MK3S hotends, maintaining compatibility with the printer firmware and connector layout. Its compact design allows straightforward installation in the hotend block, and the component is suitable for long-term use as part of routine maintenance or after a malfunction of the original sensor. Using a dedicated Prusa-compatible thermistor reduces the risk of temperature-related print defects and supports accurate PID control.

Restoring correct thermal feedback after hotend servicing or nozzle replacement
Key specifications
Type: NTC thermistor optimized for 3D printer hotend temperature measurement
Compatibility: Designed for Prusa MK3 and MK3S hotend assemblies
Form factor: Small, insulated sensor element suitable for insertion into the hotend block
Connection: Wire lead matching Prusa hotend connector and wiring layout
Function: Provides feedback for temperature control and PID regulation during printing
How to use
Turn off and unplug the printer before starting any repair. Remove the hotend assembly according to the manufacturer’s service instructions and access the thermistor pocket in the hotend block.
