  • How to disable a compartment


For over-and-under and side-by-side models, it is possible to turn off one section of a combination unit for an extended period without disrupting the other. 

To turn section off:

  1. Turn the unit off by pressing the POWER key.
  2. Press and hold the WARMER key of the section you want to disable. You should hear a beep indicating that the button has sensed your finger.
  3. While still holding the WARMER key, press the POWER key.
  4. Release both keys.
  5. The disabled section shows a double dash "--" in the control center display panel.

To turn section back on:

  1. Repeat the process above in the same order to turn the section back on.

If the section will not turn off or back on again:

If the steps above fail to enable or disable the desired zone, try again. Make sure the unit is being turned off first.

  • A beep indicates the button sensed the touch input.
  • Lights function in the disabled section.
  • Note: On all series, disabling a zone will have no effect on the light terminator. The lights still go out if the door is left open.
    • If the lights go out due to the light terminator, the door will need to be closed without opening for 45 minutes before the disabled section can be turned back on.
    • Bypass the 45 minute wait by resetting the circuit breaker. The disabled zone can then be turned on.
    • Refer to Sub-Zero Light Terminators for more information.
