The RDTM answer in short
Warm inside and clearly running is the classic airflow complaint on an AVG RDTM refrigerator. The compressor is doing its job and the cold is not reaching the shelves — frost on the evaporator, dust on the condenser, or a fan that has stopped turning. Start with the two you can see and hear before anyone quotes you a sealed system.
What owners describe
- Condensation or sweating on the outside of the cabinet — On every RDTM model in the table, a door that no longer seals lets humid room air in continuously and the unit cannot win against it.
- The compressor runs and never stops — Looking at RDTM models specifically, a unit that cannot reach temperature never satisfies its thermostat, so it simply keeps going.
- Food safety is already marginal — A refrigerator holds food safely at 40 °F (4 °C) or below; above that the clock has started.
- Warm air blows from the vents instead of cold — Across the RDTM line, air movement without chill means the cold side of the loop is iced or starved.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power, start-relay or control fault, and it is a different page. If you hear nothing at all, go there instead.
What actually fails on RDTM models, in order
- A stalled defrost cycle icing the evaporator — Ranked here because adaptive defrost stalls quietly long before it fails outright: the ice sheet grows over weeks and the owner notices warmth, never frost.
- A door gasket that no longer seals — It earns this rank because a gasket leak is continuous: the machine never stops fighting the room, so it never cycles off. That is the position it takes on this family.
- A thermostat or thermistor reading the cabinet wrongly — A sensor that reads cold when the box is warm stops the compressor early and the cabinet coasts upward.
- A sealed-system or compressor fault — It comes last because everything above it is cheaper, more likely and checkable without a gauge set — and because this one needs a licensed technician. The RDTM models in the table below are no exception.
Where to start, and what follows
- Open the door and listen for the circulating fan — On an RDTM model, hold the door switch in if you must — the fan should be audible within a second or two, and silence narrows the list immediately.
- Look at the rear panel for a frost sheet — A light dusting is normal; a crust you can tap with a fingernail is the airflow blocker itself.
- Listen for whether the compressor ever stops — On an RDTM model, a unit that cycles is reaching its setpoint; one that runs continuously is not.
Before you take any panel off
Safety
Pull the plug or trip the breaker first — a capacitor can hold a charge after the power is off. Two people move a loaded cabinet, not one: these machines are top-heavy with the door open, and a dropped cabinet flattens the condenser tubing. Keep the door switch and its harness intact throughout.

When this stops being an owner job
The line is simple: anything you can reach without a meter is yours, and everything behind the evaporator panel is not. A fan motor, a defrost heater or a thermistor is a bench job with live terminals; a gauge on the sealed system is a licensed job. Bring someone in as soon as the cabinet will not hold 40 °F (4 °C) after a full defrost and a clean coil.
