Bertazzoni Freezers ERROR CODE... Error: Internal fault — check code

What Does Error Code… Mean? The Error Code… message on a Bertazzoni freezer column — including Professional Series and Master Series built-in models — indicates the control board has detected and stored a specific internal electronic fault. The three dots are intentional: the actual fault identifier is one button-press away. Hold the Alarm button and […]

Quick Assessment

Answer to continue safely

Is it safe to keep using?

No. Move frozen food to a secondary freezer until the numeric fault code has been assessed by a technician. Some codes indicate the freezer has stopped cooling entirely; others allow short-term continued use. Without knowing the specific code, treat the situation as a stop-use fault.

Can I reset the code?

No. A power-cycle may temporarily clear the display, but the fault will return unless the underlying component is repaired or replaced by a service technician.

When to stop immediately?

Stop if you notice: Frozen goods begin to soften within 2 hours of the alarm appearing, Any burning smell or unusual noise from the compressor or fan area.

Symptoms You May Notice

Alarm indicator light on the control panel flashes at a steady rate

The Alarm button begins flashing rhythmically — the visual signal that draws attention before you read the display message. The steady cadence distinguishes this from a door-open or temperature alarm, both of which have different flash patterns.

Freezer may continue running but temperature control becomes unreliable

Depending on the fault type, the freezer column may continue operating in degraded mode — maintaining an approximate temperature but unable to hold it precisely — or may cease freezing entirely. Frozen goods should be monitored closely.

Holding the Alarm button reveals a numeric fault code

Pressing and holding the Alarm button cycles the display to show the stored fault code (e.g., F1, F2). Write this number down — it is the key piece of information for your service call.

Possible Causes

1

Temperature probe open or short circuit

An NTC thermistor monitoring the freezer zone or evaporator has failed in an open- or short-circuit state, causing the control board to log a probe fault and potentially lose accurate temperature control.

Requires Professional
2

Communication fault between main board and display module

A connector in the wiring harness linking the main control board to the display has come loose, or a component on either board has failed, breaking the internal communication bus.

Requires Professional
3

Compressor or evaporator fan motor fault

The compressor overload protector tripped due to overheating or a refrigerant fault, or the evaporator fan motor logged a failure event. Either condition is recorded as a fault code on the control board.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Record the numeric fault code from the display

    Press and hold the Alarm button until the display switches to show the numeric fault code. Write it down exactly and photograph the display. This code determines the repair needed and must be communicated when booking service.

    Do not press any other buttons while reading the code — on some models additional presses cycle through secondary codes.

  2. 2

    Perform a single power-cycle

    Turn the dedicated circuit breaker off for 2 minutes, then restore power. Wait 15 minutes and check whether the Error Code message returns. If the code does not reappear and freezer temperature is stable, monitor for 24 hours.

    If the code returns within an hour, stop power-cycling. Repeated resets will not fix an electronic fault and may mask secondary issues.

When to Call a Professional

Contact a qualified technician if:

  • Any Error Code... alarm that returns after a single power-cycle requires manufacturer diagnostic software and certified parts to resolve
  • Numeric fault code pointing to a compressor, sealed-system, or board fault cannot be addressed by the owner
