The short answer
A AVG RDTM cabinet that runs and stays warm is telling you that the cold is either not being made or not getting to the load, and on this family those two possibilities are separated in the first two minutes. Heat leaves at the condenser behind or beneath the cabinet, close enough to the floor that carpet and dust matter.
What you observe on these models
- The cabinet is warm and the machine is plainly running — A unit that is working and never arriving is the presentation this page is about, and it is not the same fault as a cabinet that is silent.
- One part of the interior is right and another is not — A temperature that varies across the cabinet is an airflow report.
- The cabinet recovers overnight and drifts by day — That pattern points at the room rather than the machine, and it is the single most useful thing an owner can notice.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a power, start-relay or control fault rather than a cooling fault, and it belongs on a different page.
Causes, most likely first on RDTM
- A stalled defrost cycle — Defrost stops before it fails outright: ice builds slowly across the evaporator, airflow closes down week by week, and the owner notices the warmth long before the ice. Ice at the coil above cuts the supply to the space below, which is why the lower compartment is reported first. Ranked first on AVG RDTM, which is a compact top-mount refrigerator: that construction moves this cause ahead of where the generic ordering puts it.
- Blocked airflow inside the cabinet — Cold that is made correctly and then cannot circulate produces exactly the same complaint as cold that was never made: a warm cabinet with a machine that is plainly working.
- A dirty or obstructed condenser — The condenser is where the heat leaves. Once it is blanketed in dust or fed its own warm exhaust, the circuit cannot reject heat and the cabinet warms no matter how long the compressor runs.
- A failed circulation or condenser fan — A fan that has seized, slowed or lost its supply removes the moving air the design depends on, and the fault appears as a cabinet that is cold in one place and warm everywhere else. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Start at the heat path: check the upper compartment first: on this layout it is the source, and a fault above always reads as a fault below — The freezer rear panel from inside the upper compartment, and the base bay from behind with the cabinet drawn forward.
- Read the set point and then read a thermometer — Put a thermometer in a glass of water in the cabinet overnight rather than measuring air.
- Look at how the cabinet is loaded and where the air returns — Owners report the lower compartment because that is where the food spoils, but the fault is usually decided in the compartment above it, so pull the load a hand-width off the rear wall and give it a day before concluding anything.
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.

When to call a technician
Call when the upper compartment is cold, the vent between compartments is clear, and the lower space still will not hold temperature. Call immediately if you can smell burning, if the machine trips protection repeatedly, or if there is oil rather than water in the machine bay — oil outside the tubing means the circuit is open, and every hour it runs after that costs more to put right. One more thing that is specific to this family: the RDTM variant table on this page is the whole of what is covered here — these 2 model numbers and nothing else. If the plate on your machine is not one of them, the ranking above was not written for it.
