REPLACING PRESSURE CONTROLS WITHOUT
REMOVING REFRIGERANT CHARGE
This procedure reduces repair time and cost. Use it when
any of the following components require replacement, and
the refrigeration system is operational and leak-free.
• Fan cycle control
• High pressure cut-out control
• Low pressure control
• High side service valve
• Low side service valve
Important
This is a required in-warranty repair procedure.
1. Disconnect power to the ice machine.
2. 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.

Warning
Do not unsolder a defective component. Cut it out of
the system. Do not remove the pinch-off tool until the
new component is securely in place.
3. Cut the tubing of the defective component with a
small tubing cutter.
4. Solder the replacement component in place. Allow
the solder joint to cool.
5. Remove the pinch-off tool.
