In one paragraph
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: what feeds a machine changes when the machine changes rooms, so on a recent installation the taps, drains, vents and outlets are the first suspects. Power cycling, mode checks and door switches are owner work; sensors, wiring and the board are not. The order below is written for a unit that is new, newly installed or recently moved; a machine that has run in the same spot for years ranks differently.
What you can see and hear
- 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.
- The display is blank but the cabinet still cools — A display or panel fault rather than a control failure.
- NEAR MISS — The display dims after a while — Many cabinets dim to save energy; that is by design.
Likely causes in order
- A supply interruption leaving the control latched — First on this brand: what feeds a machine changes when the machine changes rooms, so on a recent installation the taps, drains, vents and outlets are the first suspects. 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: 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, and the last to suspect: Where some buttons work and others never do, the fault is in the panel rather than in the control behind it. The drivetrain is simple, which makes it durable — it is a real cause but rarely the first one.
Where to start and what follows
- 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 on a recently installed or recently moved unit this is what the move breaks, and it costs nothing to rule out.
- 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.
Owner-side steps
- 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 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. Refrigerant is licensed work: oil or a hiss at the compressor means stop and call, and two people move a cabinet this size.
When this becomes a service call
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.

The limits of this page
This page covers Criterion refrigerators as a class, not one family or model line. 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.
