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.
