The short answer
Half the cabinets under this badge have no electronic control of any kind. On the earlier generation the entire control system is a mechanical thermostat with a numbered dial, so there is no display, no memory and no code, and a control fault means the contacts. On the later generation there is a sensor and a board. Establish which you own before looking for anything to read.
What you are seeing
- A numbered dial and no display anywhere on the cabinet — Note: The earlier generation. There is no code to look up because there is nothing to generate one.
- Turning the dial produces no audible click across its whole range — Note: On a mechanical control that click is the contacts closing. No click means the thermostat is not switching the compressor.
- The interior lamp stays lit with the door closed — Note: A stuck door switch, which heats the cabinet continuously on either generation.
- A display showing a code or a flashing indicator — Note: The later generation. The scheme differs by production run, so read it against documentation matching your own rating plate.
- An alarm that will not clear after a door was left open — Note: A stored report of a past excursion rather than a live fault.
- The display is blank and nothing runs — Note: A supply question rather than a control question. Read the will-not-start page.
Ranked causes on this brand
- Mechanical thermostat contacts failed, earlier generation — Why this rank: First because on that generation the thermostat is the entire control system: it either closes and passes power to the compressor or it does not, and there is nothing else that could be called a control fault.
- Door switch stuck closed, both generations — Why this rank: Second because it applies to every cabinet under this badge, it warms the box continuously by leaving the lamp burning inside it, and on a later cabinet it eventually raises an alarm that looks unrelated.
- A stored alarm from a door left open or a power interruption, later generation — Why this rank: Third because it is not a fault at all: the control is reporting something that already happened, and it clears once the cabinet has held temperature again.
- Temperature sensor drifted out of range, later generation — Why this rank: Fourth because it produces a cabinet running at the wrong temperature with no other symptom, which cannot be told from a correct cabinet without measuring.
- Connector or harness corrosion at the door hinge on an aged cabinet — Why this rank: Fifth because the loom crossing the hinge is the only wiring that moves, and on cabinets of this vintage it has flexed for a very long time.
- Control board failure, later generation — Why this rank: Last because everything above it is more common, and because on this badge a board is the single hardest part to source and is identified by platform rather than ordered by name.
What to check, in order
- Look at the front of the cabinet and establish whether you have a numbered dial or a display — Why: This decides which half of the page applies, and the two share no diagnostics whatsoever.
- Press the door switch in the ceiling of the liner and watch the lamp — Why: A lamp that stays lit is the one cause common to both generations and the easiest thing here to check.
- On a mechanical control, turn the dial slowly across its full range and listen for a click — Why: A control that never clicks is not switching, whatever the dial reads.
- Measure the temperature in each compartment overnight rather than trusting the setting — Why: A dial number is a request, not a report, and on this platform the higher number is usually the colder setting.
- Ask what happened before an alarm appeared — Why: A door left open or a power cut resolves a large share of alarm complaints with no work at all.
Checks you can do safely
- Photograph the rating plate inside the liner and note whether the cabinet has a mechanical dial or an electronic display. — Tools: a phone camera — Time: ten minutes
- Press the door switch in the ceiling of the liner with a finger and confirm the lamp goes out, then release it and confirm it comes back on. — Tools: none — Time: five minutes
- If the lamp stays lit when the switch is pressed, unplug the cabinet and remove the bulb to stop it heating the box while you arrange a repair. — Tools: none — Time: ten minutes
- On a mechanical control, turn the dial slowly from its warmest setting to its coldest and listen for the contacts to click, then leave it mid-range. — Tools: none — Time: five 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
- Note the exact indication shown and look it up only against documentation matching the platform on your rating plate. — 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 cabinet is plugged in, and a capacitor can hold a charge after the plug is out. Never tape or wedge a door switch closed: a lamp burning inside a sealed insulated box is a heat source and, on older fittings, a fire risk. Do not attempt to bypass a thermostat to make a cabinet run. 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
A mechanical dial makes no click anywhere across its range, which means the thermostat has to be metered and replaced. The lamp stays lit with the door switch pressed, which means the switch has failed closed and needs replacing rather than adjusting. 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 held a correct measured temperature for a full day. A board or a sensor is needed. Take the rating plate photograph, because on this badge these are identified by platform against the group-sibling machines and sourcing determines both the cost and the timescale.

What this page does not cover
This page covers both production generations and prints no fault codes, because the indication scheme differs by production run and no code table for this brand exists in this reference. It describes no one model family. For the everyday symptom-first version of this diagnosis, use the brand page rather than this manufacturer-entity one. This page is addressed to the manufacturer entity rather than to a single cabinet, so it covers both production generations and describes no one model family. Everything here depends on the rating plate inside the liner, which names the platform and is what a parts desk cross-references against the group-sibling badges that shared it.
