What you are looking at
A freezer control that shows nothing, alarms constantly, or has stopped responding is usually reporting a door, a sensor or a power event — and on a cabinet in a garage, power events are common. The reason an alarm that is telling the truth heads the ranking on a Criterion is simple: a machine that has just been installed or moved is far more likely to be reporting its setup than its age, and setup faults appear immediately rather than gradually. Power cycling, alarm causes and door switches are owner work; sensors and boards 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.
Signs that fit this page
- A blank display on a cabinet that still runs — A display fault rather than a control failure.
- The setting will not change or does not hold — A latched control or a stuck button.
- It lights up and never runs at all — A demonstration mode or a control that is not calling for cooling.
- NEAR MISS — A cabinet that is warm with a perfectly happy display — That is the cooling page — the control sees nothing wrong because nothing it monitors is wrong.
Why it happens, in order
- An alarm that is telling the truth — Most likely here: a machine that has just been installed or moved is far more likely to be reporting its setup than its age, and setup faults appear immediately rather than gradually. A door left ajar, a big warm restock or a hot day will all push a cabinet above its set point, and the alarm is doing its job rather than failing.
- A power interruption leaving the control latched — Second on the list: Garages and outbuildings are on circuits that trip, and an interruption often leaves the control in an alarm state that outlives the event.
- A door or lid switch stuck — Third on the list, and the least likely: The switch drives the light, the fan and the door alarm; stuck, it produces a permanent alarm or an interior light that never goes out. The door hardware is light, so it goes out of adjustment before anything electrical does.
Check in this order, and why
- Put a thermometer in the cabinet and compare it with the alarm — If the cabinet really is warm, the alarm is correct and the fault is elsewhere. First, because a unit that has just been connected is far more likely to be reporting its installation than its age.
- Unplug the cabinet for a few minutes and restore power — A control that then behaves normally was latched rather than damaged.
- Press the switch by hand and watch the light — A light that ignores the switch is a direct finding and takes seconds to establish.
The checks you can do yourself
- Close the lid properly, stop opening it, and give the cabinet several hours to recover — Do not add more warm food while it is recovering; that is what caused it in most cases.

- Unplug for several minutes, restore power and allow the compressor delay to expire — Most controls hold the compressor off for a few minutes after a restart; that is normal.
About 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.
What to do before a panel comes off
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.
Where an owner fix ends
Call once the thermometer confirms whether the cabinet is genuinely warm, the control has been power cycled and the door switch is proven — sensor and board work needs a meter. One line to keep in mind while you wait: A freezer holds food safely at 0 °F (−18 °C) or below.

How specific this page is
This page covers Criterion freezers as a class, not one family or model line. Nothing more specific exists to send you to at the moment; a model-level page, once written, is linked here and is the better answer. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
