The short answer
On the MCR family, a cabinet that keeps running while the inside stays warm is a heat-removal fault rather than a power fault, and that is a different list of causes from a machine that has gone silent. 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 outside of the cabinet is unusually warm to the touch — Warmth along the sides or the back can be normal where the condenser is built into the skin, but hot with no clearance behind it is not.
- 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.
- NEAR MISS - the unit is silent and nothing is cold — No hum at all is a supply, start-relay or control fault rather than a cooling one, and it belongs on the noise page or with a technician.
Causes, most likely first on this platform
- A gasket that is no longer sealing — A seal that no longer seals is a heat load that never goes away, and a cabinet fighting one will run forever without arriving. Gaskets go hard, hinges drop, and a cabinet standing out of level stops pulling its own door shut. One catalogued model means one cabinet and one door, so the variable is not which version you own but how the door sits after the machine has been moved.
- Dust on the coil and a wall too close behind — 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.
- The part that decides when to run, or the one that moves the air — Third here. A failed fan or a drifted cold control belongs on the list, but it is worth reaching only after the free checks are clean, because both need a panel off to confirm.
- Frost closing off the airflow — Fourth. Ice that has closed the airflow path produces exactly this complaint, and it stays on the list until somebody has looked at the cold surface instead of at the dial.
- The sealed system or the compressor — Last. Last, and last for a reason: refrigerant work is licensed work, the tools are not owner tools, and the four causes above account for most cabinets that arrive with this complaint.
Check in this order, and why
- Feel the condenser and the space around it — Warm is right; too hot to keep a hand on, or airless because the cabinet is jammed against a wall, is the cause rather than a side effect. With one catalogued entry behind this page, whatever you find here is the answer for every owner of the model.
- Look at the cold surface for frost — You are looking for the difference between a dusting and a skin. A skin means airflow, and airflow explains a warm cabinet with a working compressor better than anything else does.
- 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.
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
Bring someone in when the cabinet is measurably warm and the seal, the clearance and the frost pattern are all clean, because at that point the remaining causes all need a panel off and a meter. Go straight to a call, skipping the rest, if the unit trips protection on starting or if there is a burning smell, and isolate it while you wait rather than leaving it trying.
