page sat 104gt which is 100kOhm once, i noticed my headbed on idle shows now 24C and my hotend 14C , room temp 22C on wall so i guess 24C is ok but no way 14C

measured resitance was like 300KOhm, i have other cermatic core i swaped to that restance was 150k and i adjsuted B value to 4390 so now measurmet is 22.8C which is better i think but thats on another modue.... whats a chnce that 1st one that was reading 14c is burned out?
does not look like i can swap termistor on that thing

@alexus it's not a 4930.
You need to use M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8
Obviously with the correct pin name and sensor number
