Testing the thermistor resistance

Before you install your thermeristor, you should double check that you both purchased and received the working before installing. Apply the multimeter probes to both legs, and the multimeter should display the resistance. Below is some common themeristor temperature table. If it reading room temperature, if not or resistance is jumping you may have faulty thermeristor. If so, please contact us for RMA.

FAQ:

Average life of the be slinger thermistor wiring ~500-850 hours, we recommended replacing the wiring of the thermistor every 750 hours as preventative measure

The life the toolhead thermistor, depend if wiring is strain relief but usually last bit longer at 850-1250 hours but usually recommend replacing the wiring every 1000 hours for the thermistor in Ender 3/MK3 printer for instance. If the printer is using a toolhead printer, and the module is minimal wire strain, it should last the life of expected life of the each specific module but in our testing and experience most common failure point is wiring not the actual thermistor due to wire or connector fatigue, so please ensure those are constraint and not moving during printer motion. 

Please note that the above listing indicates the average print time. The module may last longer; however, based on our experience and feedback from print farms, this represents medium data results. Your experience may vary depending on your printer and application, as using the thermistor at its rated thermal limit can also reduce its lifespan.
