This reading is real time and does not involvethe temperature control algorithm.This reading should be very close to the actual temperatureof the freezer thermistor. If the reading is drasticallydifferent than the reading from a known good andcalibrated digital thermometer, consider replacement of thethermistor.Service Test 22 – Ambient Thermistor ValueThis test will provide the current reading for the ambientthermistor. This reading is real time and does not involvethe temperature control algorithm.This reading should be very close to the actual temperatureof the ambient thermistor. If the reading is drasticallydifferent than the reading from a known good andcalibrated digital thermometer, consider replacement of thethermistor.Service Test 23 – Evaporator ThermistorValueThis test will provide the current reading for the evaporatorthermistor. This reading is real time and does not involvethe temperature control algorithm.This reading should be very close to the actual temperatureof the evaporator. If the reading is drastically differentthan the reading from a known good and calibrated digitalthermometer, consider replacement of the thermistor.SERVICESERVICESERVICE
