Help: I just used a multimeter to measure a thermal resistor, and one of the readings was 0.6 kΩ

I just used a multimeter to measure the thermal resistor, and one of the readings was 0.6 kΩ; the control panel showed a red indicator. Is it possible that this resistor is damaged? All other resistances are 117 ohms
Right, normally it’s over a hundred euros
The resistance value of the thermistor you measured is 600 ohms; it’s possible that this thermistor is of the Pt500 type. You can verify this by yourself: check the resistance value table to find out what it is at room temperature, or place it in hot water and measure the change in resistance value, then compare it with the values listed in the table. Of course, it’s also possible that this resistance value is actually damaged. Fun fact: The calibration numbers for thermal resistors mainly include platinum resistors such as Pt100, Pt1000, Pt10, Pt800, and Pt500 ； Copper resistances such as Cu50, Cu100, Cu10, etc ； Nickel resistors such as NI120, NI500, NI1000, etc., as well as the less commonly used BA1, BA2, G53. Among them, the commonly used ones are platinum resistors, whose temperature measurement range is -200~850°C, and copper resistors, whose temperature measurement range is -50~150°C.
