3. With the ice machine running, verify that the

temperature of the refrigeration line (step 2)

corresponds to the thermistor resistance reading

(step 1) as stated in the temperature/resistance

chart.

Temperature/Resistance Chart

As the temperature rises at the thermistor block, the

resistance drops.

Important

If the ohmmeter reads “OL,” check the scale setting

on the meter before assuming the thermistor is bad.
