The short answer
The two models in the Criterion WF family carry designations outside the scheme the other Criterion refrigerator families share, and nothing in the matrix ties them to those platforms. The practical consequence is that this page does not assume a layout: on these units, look at how your cabinet is actually built before working through causes, then start with the conditions around it, because ambient and installation explain more cooling complaints on small, standalone units than components do.
What you observe
- Never reaches temperature in warm weather, recovers when the room cools — Ambient and clearance rather than a fault: the machine cannot reject heat fast enough.
- Runs continuously and cools unevenly, with frost at one spot — Airflow or coil frosting, depending on whether the cabinet has a fan.
- Cools normally with the door shut but warms quickly whenever it is opened — Seal, latch or door alignment.
- Steadily warmer over days regardless of the room — Points at the sealed system or the compressor.
- NEAR MISS — no hum and no light — Power, cord or control, covered by the page for a cabinet that will not start.
Causes, most likely first on this family
- Ambient temperature and clearance where the unit stands — First on this family, and above where any paired-designation page would put it, because these two models are not established as kitchen-cabinet machines and are most often found in tighter, warmer places.
- Coil frosting or airflow blocked inside the cabinet — Second. On a convection-cooled unit this is frost on the cooling plate; on a fan-cooled one it is frost over the evaporator.
- Condenser dirt at the back or base — Third, and it makes the ambient problem worse rather than acting alone.
- Door seal, latch or alignment — Fourth, and quick to test with a sheet of paper.
- Sealed system or compressor — Last, least common, and the only cause here that needs licensed equipment.
Check in this order, and why
- Establish what your cabinet actually has — fan, coil, drain — This family is not tied to the other Criterion platforms, so the layout is something to observe rather than to assume.
- Check the room and the clearance around the unit — A hot, enclosed position explains more of these complaints than any part.
- Look for frost, and where it sits — Frost at one spot is an airflow story; frost everywhere is normal cooling.
- Paper-test the seal, then clean the condenser — Both are free, both are quick, and both are commonly the whole answer.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A rear evaporator panel comes off over live tubing and a defrost heater, so let ice melt rather than forcing the panel. Never open the sealed system or vent refrigerant — that is licensed work, and oil outside the tubing means the system is already open.

When to call a technician
Improving clearance, cleaning a condenser, testing a seal and defrosting manually are owner work. Call a technician when the cabinet warms steadily regardless of the room, when frost returns within days of a manual defrost, or when you cannot establish how the cabinet is built. Call at once if oil is visible outside the tubing.
