Error code
Refrigerator signal Symbol D
Asko refrigerator — reported by blinking lights rather than by a code. The one visual indicator on this make's refrigeration, and it is a symbol rather than a string: the RFN31831EI manual shows it flashing as a temperature alarm and gives it no meaning table of its own.

What we can confirm
Signal Symbol D, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.
The signal
Symbol D
The one visual indicator on this make's refrigeration, and it is a symbol rather than a string: the RFN31831EI manual shows it flashing as a temperature alarm and gives it no meaning table of its own. It says the cabinet has been warmer than it should be for long enough to matter — after a door left ajar, after a power cut, or because something has genuinely changed. It does not say which.

What it narrows down to

About Refrigerator signal Symbol D
What the appliance is actually reporting
The one visual indicator on this make's refrigeration, and it is a symbol rather than a string: the RFN31831EI manual shows it flashing as a temperature alarm and gives it no meaning table of its own. It says the cabinet has been warmer than it should be for long enough to matter — after a door left ajar, after a power cut, or because something has genuinely changed. It does not say which.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
RFN31831EI. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 8 of the appliance types this site publishes — cooktop, dishwasher, dryer, microwave, oven, range, refrigerator and washer — and publishes none at all for commercial line, freezer, microwave, oven, range, range hood and refrigerator. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Check the door has been closing properly, and whether the power has been off.
- Give the cabinet twenty-four undisturbed hours and see whether it clears on its own.
- If it returns with the door behaving, treat it as a cooling complaint rather than an alarm and have the condenser and air path checked.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-1406 and describe what the panel is doing before booking anything.
