Ptcr Operation Check - Manitowoc S300 Technician's Handbook

PTCR Operation Check

1. Visually inspect the PTCR. Check for signs of
physical damage.
The PTCR case temperature may reach
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.
