The short answer
The URLC roster records a single model, so nothing on this page has to be hedged across variants, and it is the only entry on that roster, so the rating plate confirms your cabinet in a single step. A refrigerator in this roster that runs without cooling is usually reporting an airflow restriction rather than a dead compressor. A refrigerator holds food safely at 40 °F (4 °C) or below, and a cabinet that has drifted above that while still running is telling you the cold is being made and not delivered.
What you observe on these models
- The cabinet is warm but clearly running — The compressor hum is there and the air inside is not cold.
- The freezer side is cold and the fresh-food side is not — Cold is made in one place and moved to the other.
- Frost building as a sheet on the rear interior wall — A layer rather than the usual light dusting.
- The compressor never cycles off — The cabinet is no longer reaching its set point, so the control never tells it to stop.
Causes, most likely first on the URLC line
- Frosted evaporator blocking the air path — Ranked first on this roster: the evaporator sits behind the rear interior panel and a frost sheet on it stops airflow before it stops heat transfer, so the cabinet warms while the compressor keeps running normally.
- Vents blocked by stored food or an overfilled shelf — It ranks second here because it is free to correct, extremely common after a big shop, and produces exactly the one-compartment-warm pattern owners describe.
- Door seal not closing, or a door left ajar — Ranked third on this roster: seals fail gradually, which is why the cabinet seems to have been fine until it suddenly was not.
- Start components or the sealed system — Ranked last on this roster: a compressor that will not come up, or a circuit that has lost charge, produces a cabinet that is not cold at all rather than one that is not cold enough.
- Body: The ranking here keeps the brand-generic order, and what the URLC line changes is the order of the checks beneath it: this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
Check in this order, and why
- Look at the rear interior wall for a frost sheet — A layer thick enough to hide the surface underneath explains the complaint on its own, and it means the defrost side is worth investigating.
- Clear the back of every shelf and find the vents — Leave a hand's width clear at the rear of each shelf, then give the cabinet a day before judging.
- Close the door on a strip of paper at several points and pull — Anywhere the paper slides out freely is admitting air. Check the whole perimeter, not just the handle side.
- Have the circuit assessed rather than guessed at — This needs gauges and a licence. Oil on the tubing at the back means the circuit is already open and it should stop running.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat the space behind it as live until proved otherwise. Defrost with the doors open and the power off, never with a heat gun or an open flame, and never by chipping at the surface. Keep meltwater away from the supply cord.

When to call a technician
Call when a full defrost, a cleared condenser and a clean paper test have all failed to hold the cabinet for a day, because that pattern eliminates everything an owner can reach. Call sooner if only one compartment is affected and the vents are already clear, because a damper or an interior fan needs a panel off. Either way, move the perishable load first: it will not survive the diagnosis.
