D. Thermistor Check
The cabinet thermistor is used for cabinet temperature control. The Control Module monitors
the thermistor to control system operation. No adjustment is required.
In the event the cabinet thermistor reading is out of range (E0 alarm).
The defrost initiation occurs every 4-hrs. of cumulative compressor run time for 25-min. To
check thermistor resistance, follow the steps below:
1. Unplug the appliance from the electrical outlet.
2. Remove the control box cover.
3. Disconnect and remove the thermistor in question.
4. Immerse the thermistor sensor portion in a glass containing ice and water for 2 to 3 min.
5. Check the resistance between the wires at the thermistor connector. Normal reading is
within 27.0 to 27.9 kΩ. If outside the normal reading, replace the thermistor.
6. Reconnect and replace the thermistor in its correct position.
7. Plug the appliance back into the electrical outlet.
