The short answer for these models
A refrigerator that hums away without getting cold has almost always stopped delivering cold air rather than stopped making it. Frost over the evaporator, a door that is no longer sealing and a condenser smothered in dust account for most of these, and all three are visible without a meter. The sealed system is the expensive answer and also the least likely one. The BD models take the same faults in a different order: a plumbed cabinet has a second source of water and a second thing to fail, and a page that ignores which one you have sends you looking in the wrong place, and the water-path checks therefore come before anything else.
How this shows up
- Before the list: which of the BD forms is in front of you — See whether the unit is plumbed. A supply line adds a whole class of fault that a manual-fill cabinet simply cannot have.
- The cabinet is warm but you can hear it running — The hum is steady and the air inside is no colder than the room after several hours.
- The sides or the back of the cabinet are hot to the touch — Warmth at the flanks is normal; heat you cannot keep your hand on is the condenser struggling.
- NEAR MISS — nothing at all: no hum, no light, no fan — That is a supply or start-relay fault, not a cooling one, and it belongs on a page about a unit that will not run.
Causes, most likely first on this family
- A condenser that cannot shed its heat — It sits at this rank because the cabinet cannot cool below what it can throw away, and a smothered coil throws away very little. This is where the order departs from the brand-level page: on the BD models the construction settles it, so the water-path checks come before the checks that lead anywhere else.
- The sealed system or the compressor — It comes last because every cheap cause above has to be excluded before anyone opens a refrigerant circuit, which is licensed work.
What to check first, and why that order
- First — shut the door on a strip of paper and pull — Do it at several points around the frame. Anywhere the paper slides out without resistance is a leak, and it takes a minute to find. On these models this is the step the construction changes: the answer only tells you something once you know which form the unit is.
- Second — feel the condenser and the air around it — Put a hand behind or underneath. The coil should be warm and the air near it should be moving; neither happens under a blanket of dust.
Before you open anything
Safety
Cut the power before a panel is disturbed, because a capacitor can hold a charge after the power is off. Defrosting with heat is how liners crack and coils get punctured; time and an open door are the only safe method. Empty the cabinet before moving it and get a second pair of hands for the weight.
Where the owner job ends
Call once the door, the frost and the condenser checks are all clean, because what is left is not an owner job. Call sooner if the cabinet never cools at all despite a compressor that runs continuously, or if you can see oil around the tubing at the back — oil outside the circuit means the system is open, and every hour it runs after that costs more to put right.
