What is happening, in three sentences
A warm MCCF refrigerator with the compressor running is a cooling-path fault, not a power fault, and that narrows the list to four candidates. Two of them are conditions rather than broken parts — where the cabinet sits and how the door closes — and both are free to exclude. A refrigerator holds food safely at 40 °F (4 °C) or below, so use that as the target rather than a guess about how cold the box feels.
How the fault presents
- The compressor runs and never cycles off — A unit that cannot reach its set point never gets the signal to stop, so it runs continuously and the same fault is visible from the other side.
- The top shelf is noticeably warmer than the bottom one — Cold air is not being circulated, so it settles instead of mixing.
- The freezer section still works but the fresh-food section does not — Cold is being made and not distributed, which points at the air path rather than the sealed system.
- NEAR MISS — the cabinet is warm and the unit is completely silent — That is a no-power or start-relay fault rather than a cooling fault, and it is a different article: check the socket, the cord and the breaker first.
Causes in likelihood order on this model group
- Evaporator iced over, so the air path is blocked — Frost belongs on the evaporator; a solid sheet across it does not. On MCCF this is where to start, because the alternative first checks all need the cabinet moved or a panel off and this one does not.
- Door seal not sealing, or the door not pulling itself shut — A gasket that has taken a set, a door that has dropped on its hinge, or a shelf holding the door open by a fraction all let room air in faster than the machine can take heat out. Ranked second because it explains the cases the first cause does not, and because on this family the two are checked from the same side of the cabinet.
- Thermostat, sensor or control set wrong or reading wrong — A dial knocked to its warmest position, or a sensor reading colder than the cabinet really is, both stop the machine asking for cold. Third: common enough on refrigeration generally, but on a cabinet of this size the two above it account for most of what walks in the door.
What to check first, second, third
- Before the first step — Give the machine an uninterrupted hour with the door shut and then judge it, because a cabinet that has been open while you looked at it will read warm for reasons that are not the fault.
- Look for a frost sheet on the freezer rear wall — A solid layer rather than a dusting confirms the airflow cause before anything is dismantled.
- Close the door on a strip of paper and pull — Do it at four points around the frame. A strip that slides out without resistance is the leak.
- Check the setting, then watch whether the machine cycles — Set it to the middle of the range and see whether the compressor responds within a few minutes.
Safety before diagnosis
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Nothing on this page requires the sealed system to be opened, and nothing on it should be read as permission to do so: the tubing is under pressure, and cutting or unbrazing it is licensed work with licensed tools.

Where the owner fix stops
Call once the owner-side checks above are clean and the cabinet is still wrong. Call without finishing the list if the fault is on the sealed system — if you can see oil at the compressor or at a tubing joint, or you smell burning — because oil outside the tubing means the system is open, and every hour the unit runs after that costs more to put right.
