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.
