The short answer
A refrigerator that runs without getting cold has usually lost airflow, not refrigerant. The compressor keeps working, the cabinet keeps warming, and the fault is nearly always upstream of the sealed system — which is the good news, because that part of the machine is where an owner can look. The URBCD key on the rating plate groups models that share their airflow layout, so the access route below holds across the family even where capacities differ.
How this shows up
- The compressor runs and never cycles off — Continuous running is the control asking for cold it never receives. Note how long it has been doing it, because weeks of it is hard on the compressor.
- Warm air blowing from the grille at the bottom or back — The condenser is dumping heat, which is normal — what is not normal is the cabinet staying warm while it does.
- Condensation or sweating on the inside walls — Beads of water on the inner walls mean humid air is getting in and not being removed, which usually rides along with one of the causes below.
- NEAR MISS — The unit is silent and nothing is cold at all — A completely dead cabinet is a supply, relay or control story. It is a short list and none of it is on this page.
What is behind it, ranked
- A failed or blocked evaporator fan — The evaporator fan is what pushes cold air out of the freezer and into the fresh-food side. When it stops, the freezer can stay near temperature while the rest of the cabinet warms up. This ranks first on the URBCD models because the rest of the order only makes sense once it has been cleared. The brand-wide page puts a door that is not sealing, or is being opened too often first; on the URBCD models a failed or blocked evaporator fan takes that place, because the platform gives you a way to confirm it without opening anything.
- A dirty condenser coil or a stopped condenser fan — This is the cause that punishes a refrigerator in a tight cabinet or against a wall: restricted airflow at the coil means the compressor runs long and the cabinet never catches up.
- A stalled defrost cycle icing over the evaporator — The defrost system fails quietly: the heater, the thermostat or the control stops doing its job and nothing tells the owner. Weeks later the evaporator is a block of ice and the cabinet is warm.
The order the checks belong in
- First — listen at the open freezer for the evaporator fan — With the freezer open, press the door switch in and listen for air movement. Hearing the fan removes this in a second; hearing nothing where there should be a rush of air is the answer.
- Second — look at the condenser coil and feel the airflow — The coil is where heat is supposed to leave. If you cannot see metal through the dust, nothing else on this list is worth checking until it is clean.
- Third — look at the freezer rear panel for a frost sheet — The rear wall of the freezer is where the evidence lives. A solid build of ice there explains a warm cabinet completely and makes every check below it redundant.
Before you open anything
Safety
Disconnect the power before you open anything. Leave the door switch wired as it is; it cuts the fan for a reason, and holding it closed with tape while you reach inside is how fingers meet a moving blade. Melt frost with time or a hairdryer on a low setting held well back, never with a sharp tool.
When this stops being a homeowner job
Call once the owner checks above are clean, or as soon as the evidence points at the sealed system: refrigerant work is licensed work and the equipment for it is not owner equipment. Call immediately if you see oil around the compressor or smell burning — oil outside the tubing means the circuit is open, and every hour the machine runs after that adds to the bill.
