Measure the resistance between the appropriate connection points of the
thermistor.
5
Check that the measured resistance value matches the resistance determined
through the measured temperature (earlier step in the procedure). E.g. R11T
thermistor:
▪
Measured temperature with contact thermometer: 23.1°C,
▪
Resistance value determined through temperature (using the thermistor
table A):
Resistance at 20°C: 24.3 kΩ,
Resistance at 25°C: 19.4 kΩ,
▪
Measure resistance between X111A pin 1‑2:
Measured resistance: 21.86 kΩ,
▪
Measured resistance value is inside the range. R11T thermistor passes the
check.
INFORMATION
All thermistors have a resistance tolerance of 3%.
Does the measured resistance of the
thermistor match with the
temperature determined resistance?
Action
Yes
Thermistor is OK. Return to the
troubleshooting of the specific error
and continue with the next procedure.
No
Replace the specific PCB, see
