Thermistor Field Testing
Use the guide below to test if a thermistor (temperature probe) is functioning properly. See the replacement parts list for
part number information. Table 2 is valid for all thermistors listed on table 1.

Establish Thermistor Temperature
 Check the display’s temperature reading.
 If a thermometer is available, use it to confirm the display’s
temperature reading by taking the temperature at the
thermistor.
 If the previously stated tasks are unavailable, then use any
reasonable means to estimate the thermistors temperature.
See form M164 for ice bath method. (ice water is 32
°
F)

Multimeter Set-up
 Use a multimeter and set it to the resistance (Ω) setting. See
Figure 1.
 Disconnect the thermistor from the controller, then connect the
multimeter to the thermistor. See Figure 1.
 Check and compare the multimeter’s reading to Table 1.

Analyze Results
 If the resistance and temperature are similar, then the
thermistor is working properly and does not need to be
replaced.
 If the resistance and temperature are not similar or the
resistance’s value is not on Table 1, then the thermistor is not
working properly and needs to be replaced.
 If the resistance reads over-limit, then the thermistor is not
working properly and needs to be replaced.
