The answer first
A refrigerator display that is blank, flashing, or showing a code is usually reporting a sensor or a door it cannot reconcile, and much of what looks like a control fault is a demonstration mode or a power interruption. The reason a supply interruption leaving the control latched heads the ranking on a Criterion is simple: these units are frequently owner-installed in a closet, a garage or a basement corner, so what feeds the machine is as suspect as the machine. Power cycling, mode checks and door switches are owner work; sensors, wiring and the board are not.
What you observe
- A code appears and the cabinet stops cooling — A sensor or a system fault the control cannot work around.
- Temperature settings change on their own or will not save — A latched control or a panel with a stuck button.
- Everything lights up but nothing ever runs — Demonstration or showroom mode, which does exactly this.
- NEAR MISS — The cabinet is warm with a perfectly normal display — That is the cooling page — the control is reporting nothing wrong because it sees nothing wrong.
Causes, most likely first
- A supply interruption leaving the control latched — Most likely here: these units are frequently owner-installed in a closet, a garage or a basement corner, so what feeds the machine is as suspect as the machine. A brief outage can leave the board in an error state that persists until the cabinet is properly powered down.
- A door switch stuck or misread — Second on the list: The control uses door switches for lights, fans and alarms; a stuck switch produces alarms, an unlit interior, or fans that never run.
- A membrane panel with failed buttons — Third on the list: Where some buttons work and others never do, the fault is in the panel rather than in the control behind it. It sits here rather than higher because the drivetrain is simple, which makes it durable — it is a real cause but rarely the first one.
- A temperature sensor out of range — Fourth on the list, and the least likely: A sensor reading impossibly high or low makes the control behave strangely — running continuously, not running at all, or displaying a code. There is very little board in these machines, so a control failure is the last thing to suspect, not the first.
The sequence that saves time
- Unplug the cabinet for a few minutes and restore power — A control that then behaves normally was latched rather than damaged. It goes first because it is the cheapest thing to rule out and it decides which half of this list you are in.
- Press each door switch by hand and watch the light and listen for the fan — A light that stays on or off regardless of the switch is a direct finding.
- Map which buttons respond — A pattern to the dead buttons makes it a panel fault rather than an electronic one.
The checks you can do yourself
- Unplug for several minutes, plug back in and allow the compressor delay to expire — Do not judge it for at least ten minutes; most controls hold the compressor off after a restart.
About 15 min
- Clean around the door switches and check they move freely — Spills and sticky residue are the usual reason a switch stops returning.
Tools: clothAbout 15 min
- Stop here if the next move needs a meter on live terminals — That is where an owner check ends and a service call begins.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Refrigerant is licensed work: oil or a hiss at the compressor means stop and call, and two people move a cabinet this size.
What needs a technician
Call with the code recorded, once demonstration mode has been ruled out, the cabinet has been power cycled and the door switches proven — sensor and board work needs a meter and the panel opened. One line to keep in mind while you wait: A refrigerator holds food safely at 40 °F (4 °C) or below.

How specific this page is
Everything above is generalized across the Criterion refrigerator range rather than tied to a model. No family- or model-specific page exists beneath it yet; when one is published it will be linked here and it will outrank this page for a named model. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
