The short version
When the BBBF line warms up while the compressor is clearly working, the defrost cycle is the first suspect. The platform uses one evaporator for both compartments, which means a stalled defrost frosts the coil, airflow stops, and the fresh-food side warms first while the freezer stays acceptable for days. That order of symptoms is the family signature.
What you will notice
- Air from the fresh-food vents feels still — For the models in the table on this page, hold a hand at the upper vent: moving air means the fan is working and the fault is elsewhere, still air names the cause.
- Ice cream softens while the freezer still looks frozen — An early freezer symptom that arrives well after the fresh-food side has warmed, which dates the fault.
- The cabinet sounds quieter than it used to — A missing evaporator fan removes a layer from the running noise, and owners often notice the change before they notice the temperature. That holds across every model this page covers.
- 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.
What is usually behind it
- A frosted evaporator from a stalled defrost cycle — First on the BBBF 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 does not vary across the models listed 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 is the same on all the models in the table 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 failed compressor start component — Last because it is uncommon and because it presents as a compressor that hums briefly and stops rather than as one that runs continuously, which is the opposite of the usual pattern.
How to narrow it down
- Listen at the freezer for the evaporator fan — First because it separates the two likeliest causes on the BBBF line before any tool comes out, and because the fan is audible with the freezer door open and the switch held. The same is true of each model covered here.
- 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 — Across the whole of this line, moving air means circulation is intact and the fault is elsewhere; still air with a running compressor names the fault immediately.
- Watch whether cooling returns after the cabinet is emptied and defrosted — Cooling that returns and then fails again after a few weeks is a defrost control fault rather than a one-off ice build.
Working safely
Safety
Isolate the cabinet at the socket or the breaker before the freezer rear panel comes off, and leave it isolated while you work. Never use a sharp tool or a heat gun to clear ice from an evaporator: the tubing is thin-walled and a puncture ends the appliance.

When to book a visit
The line on these models is the freezer rear panel: everything in front of it is an owner check, and everything behind it is service work. Call immediately if you smell burning or see oil at the compressor, because oil outside the tubing means the system is open. The models in the table behave the same way here.
