The short answer
On the MCD family a cabinet that runs without cooling is far more often an airflow or defrost problem than a dead compressor. That puts the evaporator and its fan above the sealed system in the order, which is the opposite end of the brand-generic list.
What you observe
- Freezer side still cold, fresh-food side warm — Near-diagnostic on a shared-evaporator cabinet, and it points at the air path rather than the system.
- The unit never cycles off — A machine that cannot reach its target runs continuously and works its compressor far harder than normal.
- Cooling recovers for a day after the doors are left open — Near-diagnostic for a defrost fault: melting the ice restores the air path temporarily.
- The compartment is colder at the bottom than the top — An air-distribution problem rather than a failure to make cold.
- NEAR MISS - silent and not cold — That is a no-power or start-relay fault and belongs on a different page.
Causes, most likely first on MCD
- Blocked airflow from a frosted evaporator — Ranked first on the MCD family: a compact cabinet has a single small evaporator and almost no air reserve, so frost stops the cooling almost at once. These codes share an evaporator arrangement and a defrost scheme, so a finding on one is worth assuming on the rest. What moves against the brand-generic order is lower down: condenser coil choked or its fan stalled sits above door seals, door alignment and loading here, because the family spans several sizes on one platform and it is the shared parts that wear.
- Evaporator or circulation fan not running — Second: a single small fan does all the work here, so it stops the cooling completely when it fails.
- Condenser coil choked or its fan stalled — Third: the coil is often a bare rear grid on this class of unit and needs clearance behind it to work at all.
- Door seals, door alignment and loading — Fourth: the free check, and a genuine finding on any cabinet that has started running without stopping: a seal that no longer meets loads the machine continuously.
- Sealed-system or compressor fault — Last: last, and on a compact unit it frequently costs more than the unit is worth.
Check in this order, and why
- Listen at the cabinet for the circulation fan — It separates the two likeliest causes before any panel comes off.
- Pull the unit out and check the condenser and its fan — Worth doing early because it needs no tools and no panel removed.
- Look behind the rear panel for a frost sheet — A solid sheet rather than a light dusting confirms a defrost fault.
- Test each door seal with a sheet of paper — Last, because it explains a struggling cabinet rather than a warm one.
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. A loaded cabinet is heavy and top-heavy once the doors are open, so empty it before moving it, and leave the sealed system alone entirely.
When to call a technician
Call once the fan runs, the coil is clean and the seals are good but the cabinet is still warm: what is left is the defrost circuit or the sealed system, and neither is owner work on this family.
