Manitowoc Ice Machine IB0696YC

Ensure the area around the ice machine is clear of obstacles

Gather cleaning materials (damp cloth, mild dish soap, clean soft cloth)

Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt

If greasy residue persists, use a damp cloth rinsed in a mild dish soap and water solution

Wipe dry with a clean, soft cloth

Soak probes in cleaning solution

Reinstallation and Sanitization

Sanitize ice machine and bin/dispenser interior surfaces

Disconnect power to the ice machine

Follow all manufacturer’s instructions supplied with the pinch-off tool

Position the pinch-off tool around the tubing as far from the pressure control as feasible

Clamp down on the tubing until the pinch-off is complete

Cut the tubing of the defective component with a small tubing cutter

Solder the replacement component in place

Cycle ice machine with the on/off button

Run the system to see if the control trips at the rated pressure

Enter the pressure at which HPCO opens

Is the HPCO opening at a pressure significantly lower or higher than 450 psig?

If the control opens at the correct pressure, find the root cause (Fan motor, dirty condenser, refrigeration system issue, etc.)

Leave all wiring connectors attached and perform testing within the 60 minute time delay period

Visually inspect the PTCR for signs of physical damage

Wait at least 10 minutes for the PTCR to cool to room temperature

Remove the PTCR from the ice machine

Measure the resistance of the PTCR

Enter the resistance reading for Two Terminal PTCR Black

Enter the resistance reading for Two Terminal PTCR Blue

Enter the resistance reading for Three Terminal PTCR Tan

Check if the resistance readings are within the specified range
