The short answer
On a Black+Decker refrigerator, a displayed fault with the cabinet still cold is almost always reporting a sensor or a stored state, not a dead board. A proper power cycle and a sensor comparison are both free and both come before any part is considered.
What you actually see
- The display shows a code and the cabinet still cools — A code with intact cooling is a sensor or a communication complaint, not a cooling failure.
- The panel is dark but the light inside works — Two different supplies: the lamp can be live while the control is not.
- Buttons do nothing, or one button does nothing — A single dead button is a membrane failure; a whole dead panel is a supply or board failure.
Causes, ranked for this refrigerator
- Power interruption left the control in a bad state — Ranks first because a brief outage or a switched outlet can leave a simple controller mid-cycle, and it is the single most common reason a panel behaves strangely on these units. A clean result here does not just remove one part; it removes everything that depends on it.
- Control lock or demo mode switched on — Second because a machine in a showroom mode lights its panel and does not cool, which reads to an owner as a broken board. It is worth being sure about this one rather than half-sure, since everything after it assumes a verdict.
- Temperature sensor open or shorted — Third because a thermistor is the part most likely to fail on a simple control, and its failure is what most displayed codes are actually reporting. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
What to check, in order
- First — a power cycle — Note whether the fault returns immediately or takes days. An immediate return rules the power cycle out cleanly.
- Second — the control lock and any showroom mode — Hold each panel button in turn for several seconds and watch for a lock icon or a mode change. The manual sequence usually uses two buttons together.
Checks an owner can do safely
- Step 1. Power-cycle the unit properly — Unplug it, wait several minutes until the panel is fully dead, then plug it back in. A quick pull and push does not clear a stored state.
Tools: noneAbout 10 min
- Step 2. Check for a control lock or a display mode — Hold each button for several seconds and watch for a lock symbol or a mode indicator. Two buttons pressed together is the usual unlock sequence.
Tools: noneAbout 10 min
- Step 3. Test the door switch by hand — With the door open, press and release the plunger. It must move freely and the interior lamp must follow it exactly.
Tools: noneAbout 5 min
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, so treat a stored charge as live even when the cord is in your hand. Do not run the machine with a panel off to watch what happens, and do not defeat any switch that cuts power when a door opens.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. Call when the sensor reads correctly, the connectors are clean, the door switch works and a proper power cycle changes nothing — what is left is measured, not inspected.

It does not cover a specific family, a specific model number or a control board revision, and where a family or model page exists it will be more precise than this one — start here to understand the fault, then follow the more specific page for the part numbers and the board layout.
