The answer first
Loss of cooling on the BFBD line with the unit still running points at air, not refrigerant. Listen for the evaporator fan before anything else: on these models it sits behind the freezer rear panel and it is the single component whose silence separates the two most likely causes. A refrigerator holds food safely at 40 °F (4 °C) or below.
What this looks like
- The fresh-food compartment is warm while the freezer still feels cold — Across the models this page covers, the family signature for an airflow fault, because the fresh-food side is fed by air from the freezer evaporator and loses that supply first.
- The compressor runs continuously and never cycles off — A unit that never reaches its target keeps running, so continuous operation is a symptom of the fault and not a cause of it.
- A sheet of frost on the freezer rear wall — Not the usual light dusting but a solid layer, which is what a stalled defrost cycle builds over several weeks. That is true of every model this family spans.
- The kitchen itself has been unusually warm — Ambient temperature changes how hard the system has to work, and a marginal cabinet fails first in a heatwave.
- NEAR MISS: water is pooling under the crisper drawers — A drain fault, covered on the water-leak page for this family, although a heavy frost build can cause both.
Most likely causes first
- A frosted evaporator from a stalled defrost cycle — First on the BFBD line because the adaptive defrost on this platform degrades before it fails: the ice builds quietly over weeks, airflow falls away, and the owner notices the warmth long before they notice the frost. It is the same on all the models in the table on this page.
- A failed evaporator fan motor — Second because the fan sits behind the freezer rear panel and is the part that wears on these cabinets. It produces the same warm fresh-food compartment with no frost sheet to show for it, which is how the two are told apart. It does not vary across the models listed on this page.
- A damper or duct held open or closed — The path between the evaporator and the fresh-food compartment is regulated, and a damper stuck either way produces a compartment that is far too warm or unexpectedly freezing.
- High ambient temperature around the cabinet — A unit boxed into a warm alcove, or standing beside an oven, loses its margin entirely. Nothing is faulty and the cabinet still will not hold temperature.
- A sealed-system or compressor fault — Last, and the reason the order matters: it is the least common cause on this platform and the only one that is not an owner check. Refrigerant work is licensed work and the tools for it are not owner tools.
Where to start, and why
- Listen at the freezer for the evaporator fan — First because it separates the two likeliest causes on the BFBD line before any tool comes out, and because the fan is audible with the freezer door open and the switch held. This applies to the whole line rather than to one model.
- Look at the freezer rear panel for a frost sheet — Second: a solid layer confirms the airflow cause when the fan is running, and its thickness tells you how long the defrost has been stalled.
- Hold a hand at the fresh-food vents — On the models this family spans, moving air means circulation is intact and the fault is elsewhere; still air with a running compressor names the fault immediately.

Safety
Power the appliance down before any panel is removed; stored charge can remain after the supply is cut. The cabinet is heavy and top-loaded, so if it has to be pulled out from the wall, walk it out on its feet with a second person rather than dragging it.

When to stop and call
Book service when cooling returns after a manual defrost and then fails again within a few weeks, which is the signature of a defrost control fault rather than a one-off ice build, or when both compartments warm together. Every model in this family behaves this way.
