What this usually is
Controls fail loudly and sensors fail quietly. On a Candor refrigerator the useful first move is deciding which of those you have, because a drifted sensor keeps everything running while making the machine wrong. That puts a lock, demo or showroom mode at the top of the list here and a temperature sensor that has drifted at the bottom.
What owners actually report
- The display is dark but the cabinet is cold — A display fault on a working machine. Annoying, and much cheaper than the alternative.
- Settings reset themselves — Values that move on their own point at a supply problem or a board fault rather than at a user error.
- NEAR MISS — the panel is completely dead and nothing runs — That is a no-power fault, and the supply is checked before anything else.
What causes this, in order of likelihood here
- A lock, demo or showroom mode — Every modern cabinet has at least one. Electronics are checked here because a mode or a lock imitates a dead machine and costs nothing to clear.
- A damper motor that has lost position — One compartment then runs to its own rules regardless of what the panel is set to. It sits at this point because the control reports conditions truthfully far more often than it fails.
- A supply event — a surge, a sag or a brownout — Control boards are the part that remembers a power event. Settings that reset themselves, or a panel that behaves differently after an outage, point straight here. Supply is proved before anything is condemned, because a dead outlet and a dead appliance look identical.
- A temperature sensor that has drifted — A sensor that reads warm makes the unit run forever; one that reads cold makes it stop early.
What to check first, second, third
- Ask whether the symptom started after a power event — An outage, a storm or a generator switchover in the days before the fault is genuine diagnostic evidence.
- Cycle the door open and closed with the alarm sounding — Many alarms need a door cycle to clear once the condition has gone.
- Compare both compartments against thermometers — A single compartment disagreeing points at its damper or its sensor.
- Note whether the code appears at the same time each day — A code tied to the defrost cycle names the system before anyone opens anything.
The checks you can do without a meter
- Verify the actual temperature independently — A refrigerator is safe at 40 °F (4 °C) or below.
Tools: thermometer
- Record the code and what the machine physically does — Runs constantly, never runs, runs and stops — that behaviour paired with the code is most of the diagnosis.
- STOP before opening the control housing — Sensors and boards are tested with a meter on live terminals behind a panel. That is where an owner check ends.

Safety
Unplug the unit before any panel or control housing is opened — a capacitor can hold a charge after the power is off. Do not silence a temperature alarm and walk away: the alarm is usually right, and the food is the thing at risk.
The line between a fix and a service call
A cabinet that is both complaining and warm is a food-safety problem before it is a repair problem: move the food, then call. A cabinet that is complaining and cold can wait for a scheduled visit.
