Service Test 20 – Fresh Food Thermistor
Value
This test will provide the current reading for the fresh
food thermistor. This reading is real time and does not
involve the temperature control algorithm.
This reading should be very close to the actual
temperature of the fresh food thermistor. If the
reading is drastically different than the reading from
a known good and calibrated digital thermometer,
consider replacement of the thermistor. Consider any
reading within 5 degrees of a known good calibrated
thermocouple acceptable.
This display would indicate a reading of 37 degrees.
