Re: hub flex zone not cooling

  1. Verify the door has not been left open.
  2. Verify the seals around the door are not dirty. Dirty seals can cause gaps large enough to let in warm air, which affects cooling.
    • If the seals are dirty, clean them and allow 24 hours to regain temp.  
    • If the seals are damaged, service is required.
  3. Cut the power to the refrigerator for 2 minutes (unplug it or flip the circuit breaker), and then restore power. If after 3 hours, the fridge is still not cooling, service is required.

Make sure that the unit is leveled. A properly leveled unit can prevent potential cooling issues, noises, or leaks, your refrigerator needs to be level. This link below will show you how to level your fridge and make minor leveling adjustments 


If the unit does not appear to have any power at all (the control panel is also blank and none of the lights come on when the door is opened), this is a different issue and needs to be brought up in its own thread.


Make sure the Cooling Off Mode is turned OFF. (see instructions below)


  • Navigate to and open Fridge Manager.
  • Touch Fridge Settings.
  • Touch Cooling Off.
  • Touch Activate.
  • Touch Proceed.
  • When Cooling Off mode is turned on, all the cooling functions will stop. Touch Close.
  • To disable Cooling Off mode, touch Deactivate and then touch Proceed.


If the refrigerator is not in Cooling Off mode, has power, and is still not cooling at all, unplug the refrigerator (or flip the circuit breaker) for 5 minutes, then plug it back in. Wait about 2 hours and if the refrigerator still does not cool, service is required.




If all of this has been completed then service repairs are what is needed. You may message us with the model code and serial number in order to verify the warranty term.
