NOTE:
210°F (100°C) while the compressor is running. This is
normal. Do not change a PTCR just because it is hot.
2. Wait at least 10 minutes for the PTCR to cool to
room temperature.
3. Remove the PTCR from the ice machine.
4. Measure the resistance of the PTCR as shown.
The resistance reading must be between:
•
S600/S850/S1000 =18 to 40 ohms
•
S1200/S1400/S1600/S1800 = 8 to 22 ohms.
