Ariston Refrigerator Error Code F1

F1 on an Ariston refrigerator indicates that the freezer temperature probe has been detected as either open circuit or short circuit by the control board. This means the board cannot read the freezer temperature accurately. When this fault is active, the compressor runs on a timed cycle based on room temperature rather than actual freezer conditions. If the probe recovers on its own, the error clears automatically.

The refrigerator will continue operating in a fallback timed compressor mode when F1 is active, so it is not completely without cooling. However, because the control board cannot monitor actual freezer temperatures, it cannot guarantee proper food safety temperatures are being maintained. It is advisable to check freezer contents and use a standalone thermometer to verify temperatures, and to have the probe repaired as soon as practical.

Repair costs vary depending on the failed component and labor rates in your area. A replacement freezer thermistor probe is typically an affordable part, often in the range of $15 to $50, and a DIY repair is possible if the wiring is accessible. If a technician is needed for diagnosis and replacement, total costs including labor could range from $80 to $200 or more. A control board replacement, if required, would be at the higher end of that range or beyond.

A manual reset will not reliably clear the F1 error if the underlying probe fault is still present. The error is designed to clear automatically once the freezer probe returns to normal operation. If the probe or its wiring is genuinely faulty, the code will return shortly after any reset. Fixing the root cause, either replacing the probe or repairing the wiring, is required for a permanent resolution.

Start by checking the wiring and connector between the freezer probe and the control board for damage, looseness, or corrosion, and reseat the connector firmly. If wiring looks intact, disconnect the probe and test its resistance with a multimeter to determine if it has failed open or short. A faulty probe will need to be replaced with a compatible part. If the probe tests correctly but the error persists, a control board issue may be the cause.
