What OF OF means on this model
Not a fault. The cabinet is in its showroom or demonstration mode, which holds the temperature display at a fixed value and stops the compressor running. It is one of the most frequently misdiagnosed situations on a display refrigerator.
Symptoms you will notice
- Panel lights up but nothing cools and the compressor never runs
- Temperature display is static or scrolling
- Fan works in showroom mode while the cabinet is not cold
- Code appears on a recently delivered or serviced unit
Common causes
The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:
- Cooling off or demonstration mode enabled in the factory
- Mode left on after a showroom display or a delivery test
- Mode turned on accidentally during a control reset
What you can safely check
These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.
- Look for the cooling off indicator or the demo message on the panel.
- Follow the manual procedure for your model to exit cooling off mode, which is usually a held button combination for a few seconds.
Do not do these
- ×Do not call a technician before confirming cooling off mode is not active. This is one of the most frequently misdiagnosed situations on display fridges.
When to call a technician
Worth scheduling, and worth your own checks first
You can usually keep living with this for a short while, but it will not fix itself. Do the safe checks below first, because a tripped switch or a blocked airflow is a five-minute fix that would otherwise cost you a service call.
- If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.
