The short answer
Most control complaints on a European refrigerator are not board failures. A door switch that has stuck closed leaves the lamp burning inside a sealed cabinet, which warms it and, on models with a display, raises an alarm. Beyond that, the numbered dial on this platform is a setting range rather than a temperature, and it is very commonly read the wrong way round.
What you are seeing
- The interior lamp stays on with the door shut — Note: A stuck door switch. It heats the cabinet and it is the top-ranked cause on this page.
- A temperature alarm that will not clear after a door was left open — Note: A stored alarm state rather than a fault. It clears once the cabinet has pulled back down.
- Turning the dial makes no audible click anywhere across its range — Note: On a mechanical control that click is the contacts closing. No click means the thermostat is not switching.
- The cabinet is far colder or far warmer than expected at a sensible setting — Note: The dial is being read as a temperature when it is a setting range.
- The display is blank and nothing runs — Note: A supply question rather than a control question. Read the will-not-start page.
- The display shows a code — Note: The code set differs by generation, so read it against the documentation matching your rating plate rather than any general list.
Ranked causes on this brand
- Door switch stuck closed, lamp burning inside the cabinet — Why this rank: First because it is common on a platform where the lamp and switch sit in the ceiling of the liner, because it directly warms the cabinet, and because it produces both a temperature complaint and an alarm at once.
- A stored alarm from a door left open or a power interruption — Why this rank: Second because it is not a fault at all: the control is reporting something that already happened, and it clears once the cabinet recovers.
- The setting dial misread as a temperature — Why this rank: Third because the numbers on a mechanical European control are a setting range, not degrees, and reading them backwards produces both far too cold and far too warm as complaints.
- Mechanical thermostat contacts failed open or welded closed — Why this rank: Fourth: it is a real failure with a clear test by ear, and it is the whole of the control system on the direct-cool half of this platform.
- Temperature sensor out of range on models with an electronic control — Why this rank: Fifth because it produces a cabinet that runs at the wrong temperature with no other symptom, which is hard to distinguish without measuring.
- Control board failure — Why this rank: Last because everything above it is more common, and because on this platform a board is cross-referenced to a group-sibling machine rather than ordered by badge.
What to check, in order
- Close the door slowly on a phone recording video, or press the door switch by hand and watch the lamp — Why: A lamp that stays on with the door shut is both the top cause and the easiest thing in the cabinet to check.
- Establish which control you have: a numbered mechanical dial or an electronic display — Why: They share no diagnostics at all, and this decides which half of the page applies to you.
- Turn a mechanical dial slowly across its full range and listen for the contacts to click — Why: A control that never clicks is not switching the compressor, whatever the dial says.
- Measure the actual temperature in each compartment overnight rather than trusting the setting — Why: A number on a dial is a request, not a report, and the two diverge.
- Ask whether a door was left open or the power was interrupted before the alarm appeared — Why: That question resolves a large share of alarm complaints without any work at all.
Checks you can do safely
- Press the door switch in the ceiling of the liner with a finger and confirm the lamp goes out. Release it and confirm it comes back on. — Tools: none — Time: five minutes
- If the lamp stays on when pressed, unplug the cabinet and remove the lamp bulb to stop it heating the cabinet while you arrange a repair. — Tools: none — Time: ten minutes
- Stand a thermometer in a glass of water on a middle fridge shelf and another in the freezer, and read both overnight before opening the doors. — Tools: two thermometers — Time: overnight
- On a mechanical control, turn the dial slowly from its lowest setting to its highest and listen for an audible click, then set it mid-range. — Tools: none — Time: five minutes
- Switch the cabinet off at the outlet for several minutes, restore power and see whether a stored alarm clears once the temperature recovers. — Tools: none — Time: a day
- Note the exact code or indication shown and look it up against documentation that matches the rating plate on your cabinet. — Tools: the rating plate details — Time: a quarter of an hour
Before you open anything
Safety
Unplug the refrigerator before removing a lamp, a lamp cover or any panel. The start relay and overload sit on the compressor pins at mains potential whenever the unit is plugged in, and a capacitor can hold a charge after the plug is out. Never tape or wedge a door switch closed to keep a lamp working, and never defeat it to test something: a lamp burning inside a sealed cabinet is a heat source and, on older fittings, a fire risk. Discard food that has been above a safe temperature while an alarm was active. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service A refrigerator holds food safely at 40 °F (4 °C) or below. — Id: fridge-40f
Where the service line falls
The lamp stays lit with the switch pressed, which means the switch has failed closed and needs replacing rather than adjusting. A mechanical dial makes no click anywhere across its range, which means the thermostat is not switching and has to be metered. The measured temperature is wrong at every setting on a cabinet with an electronic control, which points at the sensor or the board. An alarm persists after the cabinet has been running at a correct measured temperature for a full day. A board is diagnosed as failed, in which case ask for the group-sibling cross-reference before agreeing, because sourcing determines both cost and timescale here.

What this page does not cover
This page is generalized across families and models and covers both mechanical-dial and electronic-display cabinets sold under this badge. It prints no fault codes, because the indication scheme differs by generation and no code table for this brand exists in this reference. It does not describe any one model family. For parts sourcing and for telling one production generation from another, work from the manufacturer-entity page rather than this one: the same platform was sold under several group badges, and a parts desk cross-references by platform rather than by the name on the door.
