If the display or lights of the GE Profile PVD28BYNFS look wrong, GE's own article for a refrigerator that is not running starts with Demo Mode: if 0F 0F appears on a pushbutton display, or dE no or Showroom Mode appears on an LCD display, or the ice dispenser does not work, the refrigerator is in demo mode, and the article lists the key combinations to clear it (for example holding Lock Controls and Precise Fill for 5 seconds). The manual adds that the controls ship covered by a protective film, the LED lights need an authorized technician to replace, and Sabbath mode dims and suspends features until it exits.

How to confirm Hold Settings, Water and Light for 3 seconds to exit; it exits automatically after 96 hours
- 3
Protective film left on the controls
What separates it The buttons respond poorly on a new installation because protective film was left on the controls
How to confirm Remove the protective film over the controls, and try again

How to confirm An authorized technician must replace the LED assembly
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact text on the display, such as 0F 0F or dE no
- Whether the refrigerator is cooling and the fan running
- Whether Sabbath mode was set recently

0 of 5 completedRead the display
Reversible0F 0F on a pushbutton display or dE no or Showroom Mode on an LCD display means Demo Mode. Note which appears.
Clear demo mode
ReversibleTry the combination for your model: hold Lock Controls and Precise Fill for 5 seconds and press Yes when asked; or Freezer, Refrigerator and Crushed for 5 seconds; or Freezer, Refrigerator and Auto Fill for 5 seconds; or Refrigerator, Smart Heating and Ice for 5 seconds.
Set the temperatures
ReversibleWhen demo mode is off you hear a beep and the demo text goes. Adjust the refrigerator and freezer temperatures and allow 24 hours to stabilize.
Check Sabbath mode
ReversibleHold the Settings, Water and Light buttons for three seconds to enter and exit Sabbath mode. The display shows a Fixed Screen with an Exit Sabbath mode button when the Shabbos Keeper is connected.
Use the dispenser light control
ReversibleUse the dispenser light control, since the Light button controls the dispenser lighting and a chime accompanies each press.
Model-specific
What is true of this model and not of its siblings
- Lighting and display notes
- There is LED lighting in the refrigerator compartment, at the bottom of the left-hand refrigerator door and at the bottom of the convertible drawer. If an assembly needs replacing GE directs owners to its service line. The controls ship with a protective film that must be removed, and software updates mean the latest functions are in the owner's manual online.
