Control board (kart) failure stopped cooling on Beko 678551 ESC
Owner of a 3-year-old 678551 ESC reports sudden loss of cooling; Beko service diagnosed a card (kart) fault, fitted a replacement card that did not fix it, then ordered a compressor. The fridge was unusable for days and the food spoiled. This is a model-specific electrical failure on the exact subject code.
What to check. The control board is a known failure point on this model; a card fault can take the whole fridge down and may not be resolved by the first card swap, and parts can take days to arrive.
An owner of the 678551 ESC reports the front dampered glass door broke shortly after purchase and the claim became a warranty dispute. The glass front is a fragile, expensive part on this model.
What to check. The 678551 ESC has a dampered glass front that an owner reports breaking, leading to a warranty fight; the glass door is a costly part to replace out of warranty.
A separate complaint on a 678551 no-frost unit (the 'edi' variant of the same base model) reports the control card failed and the replacement had to be sourced from production, causing a long wait. This corroborates the control-card failure pattern across the 678551 no-frost family.
What to check. Control-card failure appears across the 678551 no-frost family, and replacement cards may be slow to source, leaving the fridge down for days.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
