The short answer
A unit from the RMRS family that runs without holding temperature has lost the ability to move heat out, not the ability to work, and the distinction decides everything below. When one of these units stops holding temperature the machine usually keeps running, and that is the single most useful clue on the page: a unit that runs and stays warm has a heat-removal problem, not a power problem.
What you observe on these models
- The compressor runs and never cycles off — A unit that never reaches its setpoint never satisfies its control, so it simply keeps going. Long run times are a symptom of the fault, not a second fault.
- The interior light is on and the fan is silent — Where a model has a fan behind the rear panel, silence from it with the door held open is a strong pointer, though door switches complicate the test on some cabinets.
- It cools better when it is nearly empty — A unit that copes until it is loaded is running out of capacity rather than failing outright, and that points at airflow and at the seal before it points at the compressor.
- NEAR MISS - it cools everywhere except the ice compartment — That is an ice production complaint rather than a cooling one, and the page for that fault takes it from the other end.
Causes, most likely first on this platform
- Frost closing off the airflow — Cold has to be made at one surface and then carried everywhere else. Let frost bridge that surface and the air stops passing through it, so the cabinet warms while the machine works harder than it ever has. Every entry here sits on one base, so the cold system is common to all of them and the fault that leads is the one that system produces on its own.
- Heat that cannot get out of the cabinet — Second on this platform. A blanketed condenser costs capacity rather than killing it outright, which is why it tends to show up as a cabinet that copes in winter and gives up in summer.
- A gasket that is no longer sealing — Third here. A hardened gasket or a door that no longer closes under its own weight will hold a cabinet several degrees warm indefinitely, which keeps it in the running whatever else is suspected.
- A stalled fan or a control that has drifted — Fourth. A dead fan or a control that has drifted stays on the list, but it is worth reaching only once the free checks are clean, since confirming either needs a panel off.
- The sealed system or the compressor — Last. Bottom of the list on purpose: the tools are not owner tools, the work is licensed, and the four causes above account for most cabinets arriving with this complaint.
Check in this order, and why
- Put a thermometer in and leave it — A dial reading is a request, not a measurement. Give it several hours with the door left alone and you will know whether you have a fault at all and how far off it is. All 7 entries in the table below sit on one base, so what this check tells you holds for every one of them.
- Close the door on a sheet of paper and pull — Do it at several points around the frame. Anywhere the paper slides out without resistance is a gap, and a gap anywhere is a permanent load on the cold system.
- Listen for the fan with the door held open — Where the model has one, the fan should be audible once the door switch is defeated by the handle rather than by you. Silence with the compressor running narrows it hard.
Before you open anything
Safety
Isolate the machine at the plug or the breaker before any panel comes off, and expect a capacitor to hold a charge after the power has gone. Do not chip frost off a cold surface with a knife or a screwdriver: the tubing behind it is thin, and a puncture turns a cheap fault into a scrapped cabinet. Refrigerant work is licensed work and the tools for it are not owner tools.

When to call a technician
Call once the free checks are clean: a thermometer confirming the cabinet is warm, a seal that passes the paper test, a clean condenser with air around it and no frost skin on the cold surface together rule out everything an owner can reach. Call immediately, without further testing, if you find oil outside the tubing or smell burning, because both mean the system is open and every further hour of running costs more to put right.
