In short
When the display and the cabinet disagree, believe the cabinet. A control reading a drifted thermistor will show a confident, wrong number and run a cycle to match it, which is why temperature readings are the last thing to trust here. Work from the cheapest check to the most expensive one and the sealed system stays where it belongs, at the end. The first two steps cost nothing at all.
What you actually see
- The panel does not respond to touch — Either the user interface has failed or it has lost its low-voltage supply from the main board.
- A setting reverts on its own — The control is resetting, or a lock or demonstration mode is active.
- The display shows a temperature the cabinet clearly is not — A sensor reading the control trusts more than it should.
- NEAR MISS: nothing lights at all and nothing runs — That is a power or start problem, not a control fault.
The causes in order of likelihood
- Control lock, demonstration or showroom mode active — Most likely here. It leads here because these cabinets ship with a showroom mode that runs the lights and the display and never runs the compressor. The cheapest of all possible answers and genuinely common. The panel behaves normally but refuses every change, or the lights run and the cooling never does.
- Thermistor or temperature sensor drift — Next most likely. A sensor that reads plausibly and wrongly is worse than one that fails outright, because the control keeps running a cycle that matches the bad reading.
- User interface board or ribbon connection failure — Third in the order. Membrane panels fail at the connector and at the flex tail, particularly where they cross a door hinge.
- Moisture in the panel or behind the fascia — Then this one. Condensation in a door-mounted panel produces intermittent, wandering faults that come and go with the weather in the kitchen.
- Body: The order below is what makes this page worth reading. It is a ranking rather than a measurement, and it carries no numbers because no fact bundle supports any.
The diagnostic order
- Look for a lock indicator and try the documented unlock gesture — It is free and it resolves a real share of unresponsive panels.
- Power the cabinet down fully for several minutes and back up — A genuine power cycle clears a latched state that a quick unplug does not.
- Put a separate thermometer in the cabinet and compare it with the display — This is the test that proves whether the control is lying, and nothing else does.
- Body: The order below assumes a supervised cabinet, so it starts with the modes the supervisor may be sitting in.
What you can do now
- Check for an active lock, sabbath, holiday or demonstration mode — Each of these makes a working cabinet look broken in a different way.
- Place an independent thermometer on a middle shelf — Read it after several hours with the door kept shut, and compare it against the display.
Tools: thermometer
- Dry the panel area and watch for the fault to change — Wipe the fascia, leave the door open briefly and see whether behaviour improves.
Tools: cloth
- STOP before opening the door skin or the fascia to reach a ribbon connector — That is a service task and the flex tails damage very easily.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not attempt to dry a control board with heat, and do not keep resetting a cabinet that trips its breaker when you do.
When this becomes a service call
Call once a lock or demonstration mode is ruled out and an independent thermometer proves the display wrong, or when the panel is dead while the cabinet still cools. Those are sensor and board repairs, both of which need parts and a diagnosis rather than a reset. Move perishable food somewhere cold first, then deal with the appliance.

Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
