D. Thermistor Check
The cabinet thermistor (NTC type) is used for cabinet temperature control; the thermistor
resistance varies depending on temperature. The controller monitors the thermistors to
control system operation. No adjustment is required; the controller has the adjustment from
factory.
In the event the cabinet thermistor reading is out of range (E0 alarm), the compressor
operates on a fixed time basis of 20-min. on and 15-min. off.
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.
4) Check the resistance between the wires at the thermistor. Normal reading is within 10
kΩ at 77°F of ambient.
6) Reconnect and replace the thermistor in its correct position. See "IV.B. Important Notes
for Component Replacement".
7) Plug the appliance back in. Move the power switch to the "ON" position.
