648PRO Manual Zone Disable


  • Turn off one section of PRO48
  • Turn off the refrigerator or freezer only in a 648PRO


Model 648PRO allows for disabling the upper refrigerator, lower refrigerator and freezer all separately.

  • Always check set points after restoring normal function.
  • It is normal for zone 2 to be missing.
  • Manual Zone Disable Mode allows the user to switch one zone, or compartment OFF for interior cleaning, defrosting, or diagnostic purposes, while allowing the other zones to continue cooling.

To initiate Manual Zone Disable Mode:

  1. With the unit ON, press and hold the WARMER key for the zone being disabled.
  2. While holding the WARMER key, press the POWER key and release both keys.
  3. Double dashes will appear on the user display in place of zone temperatures, indicating all cooling functions for that zone are disabled.
  4. Repeat procedure to restore normal function.

Normal function can also be restored by touching the unit OFF, then back ON.
