- D
  dmooreAug 18, 2025
  If the barrel status is OFF on your Cornelius Beverage Dispenser, it may be because it is not activated. Turn it to ON, DFRST, or SPIN. An error might have shut off the motors, so correct the error and then turn it to ON, DFRST, or SPIN. The unit could be in diagnostics, so exit diagnostics and turn it to ON, DFRST, or SPIN. A defective touch switch could also be the problem, in which case you should replace it.

Why is the barrel frozen in my Cornelius Beverage Dispenser?
- J
  James HobbsAug 23, 2025
  If you have a frozen barrel in your Cornelius Beverage Dispenser, it may be due to low Brix. Correct the cause and reset the Brix. A broken beater bar or a broken drive coupler could also be the issue; replace these parts if broken. If there is no defrost, program defrosts in the unit, ensuring defrosts are programmed for all days by reprogramming if necessary.
