· Max Error Temp Error in Build Plate Sensor
Can you explain please: is the 192C the goal temp or the reported temp?
If it's the reported temp then the resistance is a bit high. The resistance should be around 110 ohms at room temp.
192C would imply about 173 ohms. These parts don't fail but the connection to the pt100 fails easily. Most likely the problem is where the wiring connects to the print bed. Check that the two smaller wires are screwed in tight and if so maybe take the bed completely apart (it's not hard - start with removing the 3 leveling screws) and resolder the connections of the terminal block to the circuit board inside the print bed.
Also check the wiring as shown in your photo.
