TRAINING MANUAL
THERMISTOR ASSEMBLY
Each heater includes a thermistor to regulate the heat and to power down the heater in
the event of a failure. The sensors can be tested at their location or at their connectors
on the main board.
Use an ohmmeter to check the resistance of the sensor when it is disconnected from the
circuit.
