Quick answer
F03 · a sensor issue · Bertazzoni freezer — independent summary for homeowners.
Model compatibility: Bertazzoni reuses codes across series and model years, so F03 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Homeowners usually see F03 on a Bertazzoni freezer in connection with a possible sensor-related problem. Independent technicians still match the code to your serial family before ordering parts. Two Bertazzoni units can share a display string yet mean different subsystems; verify for your serial family.

Never open the sealed cooling or refrigerant system — this must be handled by a certified technician. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
