Service Test 21 – Freezer Thermistor Value
This test will provide the current reading for the freezer
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 freezer thermistor. If the reading is drastically
different than the reading from a known good and
calibrated digital thermometer, consider replacement of the
thermistor.
Service Test 22 – Ambient Thermistor Value
This test will provide the current reading for the ambient
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 ambient thermistor. If the reading is drastically
different than the reading from a known good and
calibrated digital thermometer, consider replacement of the
thermistor.
Service Test 23 – Evaporator Thermistor
Value
This test will provide the current reading for the evaporator
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 evaporator. If the reading is drastically different
than the reading from a known good and calibrated digital
thermometer, consider replacement of the thermistor.
