C. Thermistor Check
In the event the cabinet thermistor reading is out of range (E1 alarm), the compressor
operates on a fixed time basis of 5-minutes on and 5-minutes off.
In the event the refrigerator defrost thermistor reading is out of range (E2 alarm), defrost
initiation occurs every 4-hours of cumulative compressor run time and terminates on
20-minute minimum defrost timer.
In the event the freezer defrost thermistor reading is out of range (E2 alarm), defrost
initiation occurs every 4-hours of cumulative compressor run time and terminates based
on cabinet thermistor temperature.
To check thermistor resistance, follow the steps below.
1) Move the power switch to the "OFF" position, then unplug the appliance.
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 minutes.
5) Check the resistance between the wires at the thermistor connector. Normal reading is
within 16.0 to 16.7 kΩ. If outside the normal reading, replace the thermistor.
6) Reconnect and replace the thermistor in its correct position. See "V.B. Important Notes
for Component Replacement."
7) Plug the appliance back in. Move the power switch to the "ON" position.
