Quick answer
E03 — commonly associated with a temperature-sensor issue on a Bertazzoni refrigerator. Meaning can vary by model; verify before relying on it.
Model compatibility: Bertazzoni reuses codes across series and model years, so E03 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
On many Bertazzoni refrigerator models, E03 is commonly tied to a possible temperature-sensing problem. Series and control generations differ — confirm the wording in your model documentation before acting. Treat this as independent homeowner guidance from Bertazzoni Appliance Repair, not a substitute for model-specific service literature.
Signs

A temperature sensor reading out of range

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Confirm nothing is blocking internal vents or airflow
Note the actual behavior or temperatures if measurable
Perform a manufacturer-approved restart
Keep notes on any recent power outages, filter changes, or installs before the visit
Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. 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.
Please avoid
What not to attempt
Do not open internal panels or access high-voltage components
Do not open or attempt to recharge the sealed refrigerant system
Do not bypass door locks, safety switches or interlocks
Do not keep running the appliance if there is water near electrical parts, a burning smell or sparks
