Owners who spot a blinking icon on their control panel often go searching for a code table, but the asko temperature alarm symbol is not that kind of indicator. On the RFN31831EI, a combined fridge-freezer sold through Asko’s European lineup, the manual documents a flashing “Symbol D” on the control display specifically as a temperature alarm – a warning icon, not an alphanumeric error code, and there is no separate table anywhere in that manual assigning further sub-meanings to it.
What the asko temperature alarm symbol is actually telling you
The symbol’s entire job is to flag that the interior temperature has drifted outside the range the appliance considers safe for stored food – nothing more granular than that. It does not distinguish between a door left ajar, a blocked vent, a failing compressor, or a genuine sealed-system problem; all of those conditions can trigger the same warning icon because they all produce the same underlying symptom of rising interior temperature.
Why this is different from a dishwasher or washer error code
Asko’s dishwasher and washer platforms display specific alphanumeric codes such as F12 or E23 tied to documented meanings in their own service manuals. Refrigeration is built differently: Asko publishes no error-code system for refrigerators or freezers at all, confirmed across the problem tables in the RFN31831EI, RFN22831S, and FN31842I manuals, which contain only symptom, cause, and remedy rows – never a code. The asko temperature alarm symbol fits that same pattern; it is a visual cue layered on top of a symptom-based system, not the entry point into a hidden code system.
What to check when the symbol appears
Because the symbol does not narrow the cause on its own, the useful next step is the same troubleshooting sequence used for any warm-running symptom: check that the door is closing fully and the gasket is sealing, confirm nothing is blocking the interior air vents, verify the plinth or rear ventilation is clear if the unit is built-in, and give the cabinet time to recover if the door has recently been open for an extended period, such as after unloading groceries. If the symbol clears once the temperature returns to range, the alarm did exactly what it was designed to do.
When the symbol keeps returning
A temperature alarm that clears and then reappears repeatedly, especially with no obvious external cause like a long door-open event, is worth having checked rather than dismissed, since it can point toward a slower mechanical or sealed-system issue building underneath a symptom that looks minor on the surface. A technician reading the same symbol in context – alongside compressor sound, frost pattern, and door-seal condition – can usually narrow the cause well beyond what the icon alone tells you.
Other Asko control panel symbols that work the same way as the temperature alarm symbol
The temperature alarm symbol is not the only visual indicator on an Asko refrigeration control panel that works this way – door-open reminders, filter-service reminders on models that use one, and general problem indicators generally follow the same pattern of a symbol or icon rather than an alphanumeric code, consistent with Asko’s symptom-based approach to refrigeration diagnostics rather than a code-lookup system. Recognizing this pattern helps set the right expectation before searching online for a meaning table that simply does not exist for these indicators, and it is a genuinely useful piece of context to share with a technician when describing what the panel is showing.
Where the asko temperature alarm symbol sits on the control panel
On the RFN31831EI and similar Asko refrigeration control panels, the temperature alarm symbol typically sits among a small cluster of status icons near the main digital temperature readout rather than being the only thing displayed, which is part of why it can be easy to miss at a glance if you are not used to checking the panel regularly. Getting familiar with where this indicator normally sits – and what the panel looks like when nothing is wrong – makes it much easier to notice the asko temperature alarm symbol the moment it actually activates, rather than discovering it days later during an unrelated check.
Whether the alarm can be tested deliberately
Opening the door for an extended period on purpose is a reasonable, low-risk way to confirm the alarm indicator is functioning at all, since it reliably triggers the same rising-temperature condition the alarm is designed to catch. If the indicator does not activate even after a genuinely extended door-open period, that itself is worth mentioning to a technician, since a warning system that fails to trigger when it should is its own kind of problem.
Getting it checked properly
If your Asko fridge is showing this alarm and the usual quick checks have not cleared it, our experienced, independent technicians can diagnose the underlying cause rather than guess from the symbol alone. See our guide on the door seal test, browse refrigerator symptom pages for related conditions, or book a visit through /schedule/. Asko’s own product documentation is at global.asko.com.
