The resistance value of the NTC corresponds to a temperature below -66°F (-55°C) or
above 140°F (60°C).

Do not replace the icemaker without first checking for the following faults:
1. Voltage fluctuations. If the fault code remains after switching the appliance off and
on, proceed to Step 2.
2. Faulty water inlet. (Check the water inlet.)
3. Water pressure too low. (Check the water pressure.)
4. Ice cube dispenser (output flap) is blocked. (Check the output flap.)
5. Faulty ice crusher. (Check the ice crusher.)
Only replace the icemaker after the above 5 possible causes have been ruled out.

In the compressor area, a temperature above 135°F (57°C) was detected 3 times, for
at least 5 minutes each time. The temperature readings occurred over a span of 127
minutes. During the 127 minutes the compressor is shut off so that the compressor
area can cool down. When this fault occurs, all components are shut off to avoid
damaging them from the too-high temperatures.
